Well, here it is September already, and summer is beginning to fail. So this month's column is going to have a lot of failings including some that are of the double-negative sort that come out positive. If summer fails, can fall be far behind? And without fail, year after year, autumn is the time when hi-fi falls into place again after the hot weather hiatus. We use that term "fail" too often, if you ask me. It's getting to be silly. Every single political opponent fails to do or say just about everything imaginable. I just got a snippy postcard concerning my musical broadcast in New York I "failed to identify" some of the performers. I didn't fail. I did it deliberately, because my subject was the music and its composer, and the performers were performing very well on their own, thanks. So often, you see, we are doing something positive when we "fail." Yes, this evening I failed to drink my usual martini before dinner, I had a manhattan instead. ![]() A year or so ago in this space you may well remember that I spoke of an honorable old AM-FM tuner, the Fisher Series 80, one of the first "miniaturized" hi-fi components using the then new miniature tubes and taking maximum advantage of their reduced space requirements. (My point, in case you forget, was that the enormously smaller transistor and its relatives plus the IC have led us not to smaller but to larger hi-fi units, a thought that failed to please me.) So shortly thereafter in a letter to Audio magazine (June, 1977) Burdick S. Trask of Sherman Oaks, Cal., wrote a fascinating account of his refurbished 1936 Spartan all-wave receiver, complete with bi-amped output into a 15-inch woofer and two tweeters via an electronic crossover -- for more details see the letter itself. However, before he got into that, Mr. Trask took a good humored sideswipe at me and my Fisher. It seems I "failed to mention" once again the broad and narrow band width i.f. switch on the Fisher front panel, the main use of which was to allow reasonable hi fi when an AM station came in wide, clear and, maybe, clear channel, yet in the narrow-band position reduce the hopeless AM interference, especially at night, when reception was weak and/or distant and the desired station overborne by its neighbors far and near. Selectivity. Well, with reluctance, the truth must now out. Yes, I failed to mention this useful Fisher feature, out of tact. On my Fisher the FM worked beautifully as I indicated, but the AM was dead. Well, not quite. It did produce several types of interesting hiss and the signal strength needle moved perceptibly now and then as I wheeled along the AM band. But that wasn't enough for my local weather summary, which was what I was after at the moment. On mature reflection, and since the rest of the tuner worked just fine, I decided to fail to mention the dead AM. After all, it was probably my fault. And time had indeed been passing for many a year so why not give Fisher the benefit of the advantage? And after all, too, Mr. Trask's Spartan was rebuilt by himself from the bottom upwards with new and revived parts and even some rather vital modernizations. My Fisher Series 80 was strictly on its own, never serviced in any way and still (mostly) operating. So there's one positive failure for you. I'll betcha one of you hounds could fix that Fisher in an hour or two if you got your hands on it. Just call me up and I won't charge you a thing. Historical Horrors And speaking of that, our friend Bert Whyte last year in his history of hi-fi shows missed out on (i.e. failed to mention) one of the prime marvels of the first Audio Fairs in the Hotel New Yorker over on 8th Avenue and 34th Street in the Big Apple. That august hotel, vaguely out of the art deco era (1930s?) was indeed furnished with 120 volts of electric potential in each and every room, since it wasn't nearly old enough to boast gas light. But thanks to dear old Thomas A. Edison and his latter day namesake utility, now nicknamed Con Ed, the New Yorker was provided with the very best available electricity in the mid-town area as we used to put it, 120 volts of d.c. current. And we picked that for a HiFi show! Maybe nobody realized it until the last minute. But the show must go on, and the Audio Fairs did indeed. Somebody with a proper electrical background had apparently foreseen the future and the lucrative possibilities in servicing Conventions at the hotel, electronic included. There was a modest local alternator, somewhere down in the basement, which fed a.c. to extra outlets (right among the d.c. outlets) in well, in some of the rooms. Our earliest hi-fi exhibitors, therefore, had to choose the right socket, and if they did they were rewarded with that splendid cacophony which we now find so familiar in hi-fi shows the world over. It was a brand-new sound, then, and not nearly as well appreciated as now. If the wrong socket was chosen, in haste or by unfortunate accident, then there was smoke and damage and silence except for that ominous crackling hiss. That alternator, if I remember correctly, was the handiest closing-time signal you can imagine. Right on the dot, six o'clock or whatever, the a.c. failed, whereupon the constant and excruciating blasts of nonintegrated fi from dozens of superior sources suddenly ceased penetrating every wall into four surrounding rooms and into corridors all over. And we were left in an instant with the loveliest silent d.c. illumination you can envision. The d.c. kept going it was from Con Ed. Conversations, continued, in low, hushed tones, and I'd guess there were more hi-fi deals made in those late moments of silence than in all the day's noise. All that goes back to one of T. Edison's greatest failures in the midst of his greatest triumph, the integrated electric light system as pioneered right there in New York at the famed Pearl Street power station and distribution system. That system was built on direct current, two-conductor. Very soon after, Edison worked out the three-conductor system but again via d.c. When this idea was applied to its ultimately right area, the a.c. distribution system, we had modern power but old Thomas would not go along. He stuck to d.c. and there were horrid stories perpetrated about people being fried via high-voltage a.c. in those newfangled arrangements. This was made even more gory by virtue of the new electric chair, which fried but did not quite kill one of its earliest occupants. Result was that the older Eastern cities, notably Boston and New York (and I would suppose Philadelphia) became entrenched in the d.c. system and stayed that way an astonishing number of years, right on through the 1930s. Of all the vicious impediments to fi, that of d.c. in the home was surely at that time the worst. Very nearly insurmountable. I should know; I was there. Yankee Ingenuity When I got out of college I moved to New York, right into a d.c. zone. There were plenty left, all over town. Ah, for today's ultra simple transverters, to make up a generic term! I could not exist without a record player, even then. I had a big collection of 78s, which travelled to New York from my college room with hardly more than 5 percent breakage, a near miracle, thanks to enormous care in the packing of it into my family's Ford . Naturally, I had rented my lodgings without a thought as to current and now it was too late. So I went out and bought a perfectly enormous motor-generator thing, which I could just barely lift. Installed in my modest rooming-house corner, it went on with a wham, as the d.c. lights went momentarily dim, and produced a roar of "live" noise that rivaled the sound of the (a.c.) portable phono that it fed. So, heaven protect me, I put it in the back of a deep, deep, old-fashioned clothes closet and covered the entire thing with layers of old blankets and such. The brashness of youth! Somehow, there was no fire. However, I failed to anticipate a failure to filter. There was a loud, insistent buzzing that came through my speaker whenever I played Beethoven. Was it square wave or sawtooth? I tend to think the latter. And Beethoven would have rolled over for good, because the pitch of everything, as you might guess if you are a Murphy's Law man, was about a half step too high. Most radios and phonos in those days where a.c./d.c. and these faults, even in commercial manufactured equipment, were all too common. Nasty buzzing. Wrong pitch. The very idea of fixed and stable playback speed, of course, was then relatively recent. The old acoustic machines had a loosely adjustable friction playback speed control, marked Fast and Slow, or just F and S, and you pitched things to taste, with the spring fully wound. As most of us know, the early acoustic 78s were of many speed variants in the original cutting. Fixed pitch only became really practicable in the electrical area of the 1920s, but it took many long years before the home player could match the large professional cutting table in this extremely vital respect. So-I was brought up on variable pitch, alternating with unstable pitch, as commonly found on virtually all the standard home equipment of the pre WW II period. That was a real failure, though nobody seemed to be bothered much except for a few of us musicians. With all of that, you can understand why each time hear of a new amplifier that is "flat to d.c." I give a cringe and fail to be properly impressed. In my book, d.c. is an element of hated memory. Is there any U.S. city still providing d.c. for public consumption? If there is, I don't want to hear about it, so please fail to tell me. Booming Bass One final item in the positive failure category. A few months back, I went to a fabulous "do" in a late-late New York disco-type place (it was mid-afternoon) to celebrate an ingenious new device for the disco trade (mostly) whereby a low bass portion of the musical signal is electronically transposed downwards an octave (transpose is the proper musical term) and then fed to the giant woofers via giant power amps. When this thing was operating via the house system, the bench on which I had sat down actually jumped up and down under me on every beat. Overpowering. Fantastic! The outfit behind this powerhouse bass is, of all people, dbx, a very imaginative firm if there ever was one. The only curious thing, as old readers may agree, is the title-Boom Box ! Now, not too many years ago, that term was generally derogatory and unfunny, referring to a mistuned home speaker system that produced a resonant, broken-up, false bass, not so much a thump as a thrrump. The sound had its place in the old commercial jukeboxes, which often had no highs above 2.5 kHz and made up for it by the famous basso, not so profundo, that would go right through walls. In a crowded "joint" that was all you got to hear. But when a haphazardly matched home bass-reflex system (speaker and cabinet bought separately) produced a similar thrrump, we spoke disparagingly and with disdain of the boom-box sound. We disapproved. Ask Paul Klipsch. Well, I suppose dbx really didn't know -- or failed to remember. Because they are dealing with superpower public nitery and disco-type equipment where the enormously enhanced and improved Big Boom is very much in place and in taste. I liked it! However-dbx did put on a small publicity for their Boom Box as a home device, usable even with systems of very modest power. I'd take that with some d.c. salt, if I were you. The small system won't really get much whomp out of the transposing down an octave. Not enough power and probably not enough bass range in the speakers. But if you have the prevailing super-watt big system, you may find your floor hopping and ditto for the ceiling below. But have a care with the overall level of the system. For while you may well love the effect of the Boom Box, your downstairs neighbors may fail to appreciate the unit quite so much as you do. (Source: Audio magazine, Sept. 1978; by Edward Tatnall Canby) ===== European Recordsby John Wright It is peculiar how when one new recording of a work appears, competitive versions are issued in rapid succession from other major record companies. At the moment this seems to be centered around Liszt's Sonata in B minor. Only a short while ago I had reason to enthuse about the outstanding performance by Berman on the Melodiya label (ASD 3228), which is comparatively unemotional but freely exploits the artist's dexterity. This has been swiftly followed by a performance of Vladimir Horowitz in his Golden Jubilee Recital disc on the RCA label (RL 12548). Considering his age, this is equally flamboyant but with many inexactitudes accompanied by an over-emphasis of contrasts. And now the latest release by Alicia De Larrocha recording on Decca (SXL 6756) provides a more romantic and whimsical interpretation of this rather formless sonata. It is played with a technical expertise, that in contrast to these other performances, makes it sound so easy. The piano tone is convincing, portrayed with an adequate sense of spaciousness, and the nearest comparison from my collection for such positive sentimentality and complimentary acoustics is the 1971 recording by Agustin Anievas (EMI HQS 1246) which still weathers well. However, with due consideration between these renditions, my first choice would now lie with this new Decca as the most tasteful musical/engineering balance. Albeit, perhaps, less spectacular, the record reincarnates my initial adolescent attraction to the work ... even after repeated playings. ------Alicia De Larrocha In my last record column I had cause to enthuse over Alfred Brendel's interpretation and Philips' recording of Schubert Impromptus. This month I give equally unreserved praise for Brendel's contribution to the Liszt catalogue this time with a selection of items including the well-known prelude and fugue on the name B-A-C-H. It is surely the sign of a great performer, be he actor or musician, if he can lend himself equally to a multitude of roles. The "organ-like" playing which Brendel brings to this work is in complete contrast to any other works that I have heard him play. From a technical viewpoint this release (9500 826) retains that uncanny naturalness that epitomizes the best of Philips and as such is the best recording of the Liszt discs mentioned in this issue. Also in the last column I recommended two Haydn Symphonies, The Philosopher and The Schoolmaster, played by Neville Marriner and The Academy of St. Martin-in-the-Fields (9500 198). Continuing the series, we have two more releases which are recorded in an equally luscious way, yet being clean and crisp. Haydn Symphonies 94 & 96, The Sunrise and The Miracle, are properly and frivolously performed on 9500 348 while Symphonies 44 & 49, The Mourning and La Passione, on 9500 199 are less immediately attractive but perhaps for this are longer lasting in their appeal. A quick mention of a great event is that in celebration of Vivaldi's birth 300 years ago, I Musici, celebrating their 25th Anniversary, are engaged in the recording of 10 volumes totaling nearly 50 LPs of his chamber works! Obviously at the expense involved nobody is going to purchase all or even part of this marathon on the basis of cursory remarks from me, but judging by a sampler (available at a reasonable price) I can concur that Philips have maintained their high standards of chamber music recording for which they are justifiably renowned. On 6833 247, this sampler at least is really too good to miss. Moving forward in time, musically speaking, works for two flutes by J.S., W.F., and C.P.E. Bach are played by Stephen Preston and Nicholas McGegan on DSLO 518. It is an "in-the-room" presentation being slightly dry and in need of a large listening area, allowing a good seating distance from the loudspeakers. The high cutting level results in low background noise, revealing breathy action sound of the instruments. The performance as such I would describe as "straight-laced." News from Enigma, which was started in June, 1976, by John Boyden and Peter Whiteside (being joined in December of that year by Tony Faulkner as recording manager), is of a recent takeover by WEA Records, a subsidiary of Warner Communications Inc. In less than two years Enigma has issued 45 records in addition to some 25 others already taped but not yet released. Initially it was the company's policy to concentrate on the British market but the future will involve more and more international artists. It is interesting that one of the most dynamic and modern pop record companies should have bought Enigma who are almost alone in making a classical product based upon simple microphone techniques, rejecting with scorn the widespread anti-musical multi microphone, multi-track techniques of the pop studio. Something magical generally happens when Sir Adrian Boult conducts while Parker & Bishop record for EMI. Their latest recording of Beethoven's Symphony No. 6 Pastoral with the London Philharmonic on ASD 456 is no exception. It is unashamedly warm and lyrical and is accompanied by subjectively unrestricted low frequencies, resulting in a sonic experience that can only rate as "superb." It is therefore slightly a pity that in the same period the same engineers should record the LSO conducted by Eugene Jochum performing Beethoven's Symphony No. 5 (ASD 3484) for which if there had been no direct comparison would have deserved a similar rating sound-wise. However, this just misses that higher echelon, being slightly brasher but perhaps correctly so? In complete contrast by way of balance, Brian Couzens provides a BBC type "seat-in-the-audience" perspective of the complete Sibelius Tone Poems played by the Scottish National Orchestra conducted by Sir Alexander Gibson (RCA RL 25136: 2 records). Apart from some minor pressing flaws, which are becoming more prevalent on this label of late, this whole rendition is likely to appeal mostly to the purists among us and reproduces well at low levels when listening in a quiet environment. Containing equally good distance effects, HMV's new recording of Bizet's The Pearl Fishers creates a highlight on the operatic scene (SLS 5113, 2 discs). It is rare for me to recommend opera records, and this is, regrettably, because they are usually too contrived for my tastes. While I acknowledge the dilemma presented to the engineers by this art form, I do object to "full frontal" soloists thrown before a receding orchestra. Not so in this box set, where the front-to back perspective is fine in every respect, with the orchestra (enjoyable to listen to on its own) is extended in both range and dynamics, yet with the soloists well positioned, even if synthetically, only just in front. Conceding the insuperable difficulties of opera recordings as a home entertainment medium, this version is difficult to fault and the Chorus and Orchestra of the Paris Opera, conducted by Georges Prêtre, provides an authenticity coupled to some of the loveliest music which has rightfully become very popular. Returning to music more suited to the home, Elly Ameling, accompanied by Dalton Baldwin (piano), sings Songs for Gretchen, Ellen and Suleika by Schubert on Philips 9500 169. Including the famous Ave Maria, this has similar qualities to their earlier discs of 16 Leider (6500 774), possessing a "single microphone" feeling about the balance. Equally it is emotional but unsentimental, conveying a depth of feeling yet without embarrassment. The ambience suggests a deceptive cutting level. In fact the record is not too easy to track, and I found it necessary to keep the stylus impeccably clean, but this is a small sacrifice for the satisfaction provided. It is coincidental that within the same quarter RCA should choose to issue a two-record set of Schumann Romantic Lieder sung by Peter Schreier, accompanied by Norman Shetler on RC 25126, which in its way is outstanding. It is a forward and onward going interpretation, if perhaps a little over-dedicated, but has similarities to the Schubert in the plushness of balance although comparatively sibilant in places. The market seems insatiable for records of Stravinsky's The Rite of Spring. Why this should be defeats me, since for my money if one had to extract the single Stravinsky ballet that stands repeated listening without the visual element, it would be Petrushka. However, I must be in the minority since the number of records in my collection alone disproves this. Maybe it is that, in short doses, parts of The Rite of Spring make ideal demonstration material for hi-fi enthusiasts. Following this line of thinking, and looking back through the most popular releases, there has been a distinctly "contrived" versus "purist" battle between engineers. Each strategy has succeeded within its own right, but only to a certain extent. One of the most successfully "contrived" discs with particularly impressive brass is that conducted by Sir Georges Solti on Decca SXL 6691, while a comparatively "purist" approach was taken by Philips and Haitink on 6500 482. Bridging the two approaches then came Lorin Maazel on Decca SXL 6735. And now we have yet another new disc which really does not fit into any of these categories. Conducting the Concertgebouw Orchestra, this time Colin Davis records for Philips (9500 323). It has that distinctive "laid-back" sound but with special crispness, detail, glistening transients, and differentiated timpani. So often where there is an extended bass drum, it results in a homogenous wedge. Not so here where every skin struck can be heard as a separate entity. I hesitate to call it natural but certainly it does possess that quality demanded by the pseudo-purist (despite Enigma's recent release). Containing impact, this is the very best "compromise" recording so far. Very little need be said about the playing except that it embodies a deliberately punctuated interpretation. Surprisingly for the extraordinary results achieved, there is no need to play this record loudly to maintain excitement and neither, despite the nature of the work, is it particularly tiring. To sum up I don't know how this record was made, but the results are so fine I don't even care. ========== Vintage magazine ADs:
The big difference between this cassette deck and Pioneer's new CTF1000 isn't sound. It's Value. For years, Nakamichi has enjoyed a reputation for building the world's finest cassette deck. Now Pioneer is introducing something Nakamichi won't enjoy at all: the Pioneer CT-F1000. A cassette deck that offers all the features and performance of Nakamichi's best cassette deck, at less than half the price. PIONEER VS. NAKAMICHI: THE HEAD TO HEAD COMPETITION. The $1,650 Nakamichi 100011 and the $600 Pioneer CT-F1000 are both honest three headed cassette decks that let you monitor right off the tape as you record. Both have separate Dolby systems for the playback and recording heads. So when you're making a recording with the Dolby on, you can monitor it exactly the same way. Both have two motors to insure accurate tape speed. Both feature solenoid logic controls that let you go from fast forward to reverse, or from play to record without punching the stop button, and without jamming the tape. And both are filled with convenient items like automatic memories for going back to a selected spot on a tape, multiplex filters for making cleaner FM recordings, separate bias and equalization switches for getting the most out of different kinds of tape, and even a pitch control adjustment that lets you match the pitch of a cassette to the tuning of your guitar or piano. A $1,000 GAP IN PRICE; NO GAP IN SOUND. When we built the CT-F1000, however, we did more than match the Nakamichi's renowned features. We also matched its renowned performance. Both machines boast totally inaudible total harmonic distortion levels of less than 1.5%. Both have all but conquered the problem of wow and flutter. (An identical 0.05% for each machine.) Both offer similarly impressive signal to noise ratios: 64 decibels Pioneer, 65 decibels Nakamichi. (At these levels we dare you to hear any noise at all, let alone any difference.) And finally, where the CT-F1000 delivers a frequency response of 30 to 17,000 hertz, the Nakamichi deck goes from 35 to 20,000 hertz. (We offer a little more at the bottom; they offer a little more at the top. Either way, the specifications are close enough to be called virtually identical.) A FEW PIONEER ADVANTAGES THAT AREN'T MONETARY. To prevent you from making distorted tapes, the CT-F1000 has a peak limiter that the Nakamichi machine lacks. Our tape heads are made out of a special single crystal ferrite material that's been proven to last longer than the Nakamichi's permalloy variety. And our Dolby system can be calibrated by hand while the Nakamichi 10001I requires a screwdriver. Admittedly, the Nakamichi 100011 does feature a fancy azimuth control for aligning your heads before every recording session. But we've developed a more accurate way to mount the heads in the first place. So you can spend your time recording, instead of aligning. A FEW CONCESSIONS TO NAKAMICHI. Obviously, at almost $1,000 more, the Nakamichi 100011 must offer some advantages over the CT-F1000. And we'd be remiss if we didn't point out that their VU meters extend slightly higher than ours. And that they have extra input for premixed program sources. ![]() And although their signal to noise ratio is hardly different than ours, the Nakamichi 100011 does feature an extra Nakamichi-invented noise reduction system. Considering the slimness of these advantages, the choice is clear-cut: You can buy a Nakamichi 1000II and get an incredibly expensive cassette deck. Or you can buy a CT-F1000. And get one that's simply incredible. PIONEER We bring it back alive. *Manufacturer's suggested retail price. Handles optional at extra cost.

Costly lubricants forestall drag, shedding, friction, edgewear, and annoying squeal. Checks channel loss and dropouts. Tapered, Flanged Rollers--direct the tape from the hubs and program it against any up and down movement on its path towards the heads. Stainless steel pins minimize friction and avert wow and flutter, channel loss. Resilient Pressure Pad and Holding System spring--mounted felt helps maintain tape contact at dead center on the head pap. Elegant interlocking pins moor the spring to the shell, and resist lateral slipping. Five-Screw Assembly--for practically guaranteed warp-free mating of the cassette halves. Then nothing-no dust or tape snags-can come between the tape and a perfect performance. Perfectly Circular Hubs and Double Clamp System--insures there is no deviation from circularity that could result in tape tension variation producing wow and flutter and dropouts. The clamp weds the tape to the hub with a curvature impeccably matched to the hub's perimeter.

Over the past few years numerous hi-fi companies have introduced an array of sophisticated FM tuners. All claim to make a remarkable advancement in FM reception and the claims are justified. Strong reception is an important factor in the reproduction of an FM signal. Unfortunately, the reception is only the beginning. As a matter of necessity, most FM stations compress the dynamic range of the musical material prior to transmission in order to make it easier to broadcast. All other tuners regardless of their sophistication simply decode this compressed signal and pass it along to the amplifier. The reception may be excellent, but the dynamic range of the material is still greatly compressed. That's what your amplifier will reproduce. As a result, FM reproduction is generally regarded as mediocre in comparison to records and tapes. Until now. The Phase Linear 5000-Series Two FM Tuner represents a significant sonic improvement in the reproduction of an FM signal. ![]() By incorporating a linear signal expansion circuit, the Phase 5000 Series Two successfully compensates for problems associated with signal compression, and is able to restore up to 9 dB of dynamic range.

INNOVATION - PRECISION – INTEGRITY AUDIO-TECHNICA U.S., INC., Dept. 98A, 33 Shiawassee Avenue, Fairlawn, Ohio 44313 In Canada: Superior Electronics, Inc. --------------------- Tandberg's New TD 20 A Tandberg Presents the Next Generation With The Exclusive ACTILINEAR Recording System Tape recorders can no longer be looked upon as independent units in today's extremely sophisticated sound systems, but rather as components within a total system with performance capability as technically advanced as all other components of that system. Drawing upon its unequalled 30 year tradition in magnetic recording technology. Tandberg has met this challenge by developing a completely new concept in tape recording known as ACTILINEAR Recording (Patent pending) for their new, advanced open reel and cassette machines. In conventional recording systems, the summation of record & bias currents in the recording head is done through passive components, leading to inherent compromise solutions. The new ACTILINEAR Recording System is totally free of these compromises, as the passive components have been replaced with an active Transconductance amplifier developed by Tandberg. Just a couple of its many benefits are: up to 20 dB more headroom over any recording system currently available, and the ability to handle the new high coercivity tapes. In fact, Tandberg's new ACTILINEAR Recording System, when used in conjunction with the soon-to-be-available metal particle tapes now under intense development in the U.S., Japan and Germany, offers performance parameters approaching those of experimental Pulse Code Modulation (PCM) technology, yet is fully compatible for playback on all existing tape recorders. It is literally a machine for the future, with no obsolescence factor, as it can be used with any type of recording tape, available now or in years to come. Tandberg engineers have mated this new recording system to a logic-controlled, four-motor, solenoid-less tape transport of advanced design, which, like the ACTILINEAR concept, is totally unique on the market today. Other superior features of the TD 20 A include: built-in Sel. Sync. front panel bias adjustment front panel 2-position microphone sensitivity switch frequency-corrected, peak reading VU meters, with new graphics designed for improved readability four line inputs + master gain control a "free" mode + Edit/Cue facilities for easier editing LED mode indicators separate power supplies for operational functions and audio functions rack mount capability optional wireless, PCM infrared remote control.

Every bit as revolutionary as they look, and then some. ![]() In our case, looks are never deceiving. Because all our new DC integrated stereo receivers combine unprecedentedly revolutionary styling with electronic design features that reflect JVC's more than 50 years' experience in audio development and innovation. DC POWER AMPLIFIER DESIGN Usually found only in costlier separates, JVC offers DC amplifier circuitry in all four of our new receivers. By eliminating distortion causing capacitors in our interconnecting circuit sections, JVC designers have created an amplifier that offers virtually distortion-free performance (0.03% THD) not only over the entire audio spectrum, but above and below it. As a result, all the sounds you hear are clearer, cleaner and crisper. Moreover, our DC design improves square wave performance and eliminates phase-shift-both factors being of paramount importance in distortion-free music reproduction. In addition, Triple Power Protection circuits and dual power meters give you safety and full indication of receiver operation. There are four new JVC DC integrated receivers, offering your choice of 120, 85, 60 and 35 watts/channel* respectively. S.E.A.-ALL THE WAY JVC was the first receiver manufacturer to offer a built-in S.E.A. Graphic Equalizer in a quality receiver, and we continue this tradition by incorporating this convenient feature in our entire new receiver line. Far superior to even triple tone controls, this JVC exclusive gives you complete control over the entire musical spectrum. You can attenuate or accentuate any of five separate bands, covering the entire audible range of music. And as an added feature, we've incorporated a special button so that the S.E.A. equalizer circuit can also be switched to your tape deck, so you record exactly what you hear. PUSHBUTTON SOURCE SELECTORS Unlike conventional receivers, ours incorporate an advanced pushbutton source selection panel. Color-keyed LEDs indicate the program source, and a full-function horizontal pushbutton panel provides total control over all receiver operations. Professional-type slider controls set volume and balance. SUPERIOR TUNER SECTION High sensitivity and tuning precision are featured in all four new JVC receivers. Multi-gang FM tuning capacitors, PLL MPX demodulators and other circuit refinements provide optimum frequency response and stereo separation for FM, with maximum sensitivity for AM reception—a feature often neglected in receiver designs. A thumb-control tuning wheel and accurate metering make station location and fine-tuning easy. Other features include Mode/Loudness/ Subsonic Filter switches and provision for connecting two sets of speakers. Features, styling, innovation and performance: the four main things to look for in a DC integrated stereo receiver. And you'll find them all in a JVC.

Take a look at what's taking the industry by storm. The Back Electret, another giant step forward from Sony. Never before has it been possible for thin polyester film to be used in electret condenser microphones. That's because polyester film, acknowledged as the best material for microphone diaphragms, just can't hold a static charge for a long duration. But Sony's engineers have made the impossible, possible. They've found a way to adhere the electret material directly to the back plate of the microphone. By thus putting the charge on the back plate, we are able to use polyester film in the diaphragm. The result will be obvious to your ears. Clearly superior sound quality, without particular coloration in the upper frequency range. The low mass diaphragm means better transient characteristics over the entire frequency range. DIAPHRAGM ELECTRET FILM BACK PLATE ACOUSTIC RESISTER RESISTER FRAME ACOUSTIC PHASE CIRCUIT OUTPUT TERMINAL CASE DIAPHRAGM RING SPACER LOCK RING You can find the Back Electret in four Sony microphones: ECM-56F $220; ECM-65F, $210; ECM-33F $165; and ECM-23F, $100. But you don't have to look at Back Electrets to see why Sony is ahead. NO MATTER WHAT KIND OF MIKE YOU NEED TO GET, WE'VE GOT IT. Sony's microphone line is thoroughly complete. It ranges from professional condenser to semi-professional to microphones for public address, vocalists, and outdoor use. There's omni and uni-directional. And we think it's big of us to make sophisticated miniatures. And all microphones are available with Phantom Power, battery operated, or both. So if you need something to talk into, it makes a lot of sense to talk to Sony. Write to Sony, 714 Fifth Avenue, Dept. TK, New York, N Y 10019. SONY © 1978 Sony Corp. of America.

With cassette hardware and software changing constantly, a lot of you have been waiting. Holding off for top technology. You've got it. Onkyo's TA-630D with our exclusive Accu-Bias is here. And it's the only cassette deck with adjustable bias in a two-head configuration. Which right there offers lower distortion, better low frequency response and little or no crosstalk. That's a lot, but there's more. You know how important it is to have optimum bias when you record. Too low a bias signal and you have distortion. Too high a bias signal and you lose high frequency response. Other cassette decks have adjustable bias and equalization, set at the factory for average conditions. Onkyo doesn't believe in playing averages. And gives you Accu-Bias. Accu-Bias is Onkyo's exclusive system. It works with a pair of reference signal generators built into the TA-630D. Feed these signals to your tape, and read the reproduction signal on the meters. If bias is off for that cassette tape, you compensate with continuous, variable settings until you get an absolutely flat frequency response. It's that simple...and you get the best high frequency response, least distortion and lowest signal to noise ratio. You get all that because the bias signal primes your tape as the recording is made, and every manufacturer's tape is different. Even when equalization is correct, if the bias is incorrect, it results in producing peak or losing the high frequency characteristic. Again, this depends on the tape used...al of which respond differently. Does it work? After all the effort Onkyo's gone to so you can have the only two head continuously variable bias control you might expect fantastic sound. You've got it. You've got-frequency response of 20-15,000 Hz on normal tape; 20-18,000 Hz with FeCr and CrO2. S/N ratio with FeCr is 58dB, going up to 68dB with built-in Dolby* NR System. Wow and Flutter are negligible at 0.055% WRMS by use of a DC servo motor for constant speed. There's still more, but you'll have to find out from your Onkyo dealer. Be prepared for a stunning cassette listening experience and features found only in higher priced decks. Listen for the difference Accu-Bias makes and find out what keeps Onkyo a step ahead of state-of-the-art. 'Dolby is a trademark of Dolby Laboratories, Inc. ------------------ Shure/SME new!
fact: the Shure/SME Series III is the state of the art in tone arms. Breakthroughs & Improvements. The Series Ill is the culmination of research and development extending over more than seven years. It embodies a number of significant breakthroughs as well as evolutionary improvements over its distinguished Shure/SME predecessor. Notable among these is an exotic nitrogen-hardened titanium tubing arm (with wall thickness only twice the diameter of the average human hair) providing a previously unattainable strength-to-weight ratio. The arm has a soft core annular cross-section with an internal fibrous lining which results in an efficient, natural damping of the vibration fed into the arm by the cartridge. Cartridge Carrier. The Series Ill "cartridge carrier," a combination tone arm and shell in one piece, is removable and interchangeable for multi-cartridge use. Coupling is close to the fulcrum so the carrying arm makes a minimum contribution to the Series Ill total effective mass (only 5.05 grams measured at 9 inch radius!). Fluid Damper. A built-in highly efficient F.D. 200 Fluid Damper gently but effectively resists spurious or potentially damaging stylus forces in both planes, yet does not interfere with normal arm motion. --"The best pickup arm in the world." THE SME SERIES III PRECISION PICKUP ARM WITH THE NEW SHURE V15 TYPE IV CARTRIDGE The combination of the Shure V15 Type IV cartridge and the SME Series III tonearm transcends previous tone arm-cartridge system performance, and sets dramatic new standards in connoisseur-class high fidelity reproduction. ...other features of the unique SHURE/SME Series III precision pickup arm: Unique balance system enables cartridges weighing 0 to 12 grams to be operated under conditions of minimum inertia. Interchangeable integral carrying arm replaces conventional tone arm and shell. Positive rack and pinion overhang adjustment. Main pillar hardened and ground. Low friction pivots, vertical axis: high precision fully protected ball races. Horizontal axis: knife edges. Less than .02 gram applied at the stylus will deflect the arm!

OURS LETS YOU RECORD PRECISELY WHAT YOU HEAR. Three-Head Design with Double Dolby* Not all three-head cassette decks are created equal. Some manufacturers have designed their decks with separate erase, record and playback heads primarily for convenience. So you can tape monitor as you record. But our new KX-1030 uses separate heads primarily for performance. Each designed with the optimum gap to record or play back sound more accurately. As a result, the KX-1030 has a frequency response of 35-18,000 Hz (±3 dB using CrO2 tape.) And to let you take full advantage of the separate record and playback heads, the KX-1030 has a Double Dolby system with separate circuits for the record amplifier and the playback preamplifier. That way, as you record with Dolby, you can also tape monitor with Dolby, so you hear the sound precisely as it's being recorded. The KX-1030 also has a Variable Bias Adjustment Control and a built-in oscillator, so you can adjust the exact bias for the type or brand of tape you use. We also built in a number of other features like MIC/LINE mixing, memory rewind and a peak indicator. But as good as all this sounds, wait until you hear the price. Because at $425.00, no other comparably priced cassette deck can match the performance and features of our new KX-1030. -----Variable Bias Adjust compensates for tape differences.

Here is truly a remarkable achievement in loudspeaker design and performance. The Koss CM/530 bookshelf loudspeaker sets an entirely new standard in extended bandwidth response, high efficiency, low distortion and perfect mirror-image for speakers in its size and price range and within today's technological capabilities. By designing a left and a right channel configuration for the passive radiator, the woofer and the tweeter, Koss engineers have created a perfectly matched set of bookshelf speakers that can be placed horizontally or vertically without losing the perfect right to left imaging, an incredible degree of dispersion and the beautiful Sound of Koss. To create the breathtaking depth and clarity in the CM/530, Koss engineers used an 8 inch passive radiator to radiate the sound energy over the lower two octaves. This allowed them to use an 8-inch woofer to reproduce the critical sounds in the midrange up to 3,000 Hz. In addition, the CM/530's 1-inch dome tweeter reproduces an exceptionally flat energy output and unusually low distortion that provides for a transparency and liveliness not found in other competitive speakers. Ask your Audio Dealer to give you a live demonstration of a matched pair of bookshelf speakers. You'll be amazed at their perfect mirror-image sound.
