In the following tests, recorded levels, frequencies, etc. have been controlled to laboratory tolerances-affording accurate numerical evaluation when used with oscilloscope, chart recorder, output meter, intermodulation-distortion meter and flutter meter.
1,000-Hz square waves to test transient and high-frequency response of phono pickups.
500 to 20,000 Hz frequency-response sweep.
Sine-wave tone-bursts to test transient response of pickup.
Intermodulation test using simultaneous 400-Hz and 4,000-Hz signals.
Intermodulation sweep to show distortion caused by excessive resonances in tune arm and cartridge.
1,000-Hz reference tones to determine groove velocity.
3,000-Hz tone for flutter and speed tests.
Sample waveforms-illustrating both accurate and faulty responses are provided in the Instruction Manual for comparison with the patterns appearing on your own oscilloscope screen.

STEREO DEMONSTRATION RECORD AND CASSETTE
This record (and cassette) is the result of 2 years of intensive research in the sound libraries of Deutsche Grammophon Gesellschaft, Connoisseur Society Westminster Recording Company and Cam bridge Records, Inc. The Editors of Stereo Review have selected and edited those excerpts that best demonstrate each of the many aspects of the stereo reproduction of music. The record and cassette offer you a greater variety of sound than has ever before been included on a single disc or tape. It is a series of independent demonstrations, each designed to show off one or more aspects of musical sound and its reproduction. Entirely music, the record and cassette have both been edited to provide self-sufficient capsule presentations of an enormous variety of music arranged in a contrasting and pleasing order. It includes all the basic musical and acoustical sounds that you hear when you listen to records and tapes, isolated and pointed up to give you a basis for future critical listening.
WIDE RANGE OF DEMONSTRATIONS
Techniques of separation and multiple sound sources Acoustic depth The ambiance of a con cert hall--Sharp contrasts of dynamics Crescendo and diminuendo Very high and very low pitched musical sounds Polyphony (two or more melodies going on at once) with both similar and contrasting instruments Tonal qualities of wind, string and percussion instruments Sounds of ancient instruments Sounds of oriental instruments Sound of the singing voice, both classically trained and un trained Plus a large sampling of finger snapping, hand clapping, foot stamping and other musical and percussive sounds.

BINAURAL DEMONSTRATION RECORD
This unique record presents sound of unsurpassed realism.
Binaural recording re-creates the directions, distances, end even the elevations of sounds better than any other recording method. The super-realism of binaural recording is accomplished by recording the acoustical input for each ear separately, and then playing it back through stereo headphones. Thus the sound intended for the left ear cannot mix with the sound for the right ear, and vice versa.
Binaural recording offers the listener the identical acoustical perspective and instrument spread of the original.
The sound reaching each ear is exactly the same as would have been heard at the live scene.
'MAX’-GENIE OF BINAURAL RECORDING. "Max," a specially constructed dummy head, cast in silicone rubber, duplicates the role of the human head as an acoustical absorber and reflector of sound. Super-precision capacitor microphones were installed in Max's ears so that each microphone would pick up exactly what each human ear would hear. The result is a demonstration of phenomenal recorded sound.
STARTLING REALITY. The Binaural Demonstration Record offers 45 minutes of sound and music of startling reality. You'll marvel at the eerie accuracy with which direction and elevation are re-created as you embark on a street tour in binaural sound-Sounds Of The City ...Trains, Planes & Ships ... a Basketball Game, a Street Parade, a Street Fabrication Plant. The Bird House at the Zoo-all demonstrating the incredible realism of binaural sound reproduction.
MUSIC IN BINAURAL. The musical performances presented on the Binaural Demonstration Record transport you to the concert hall for a demonstration of a wide variety of music. Selections total 23 minutes, and include examples of jazz, organ, and chamber music.
The Stereo Review Binaural Demonstration Record is the ultimate in sound reproduction. It has been made without compromise.
Although headphones are necessary to appreciate the near-total realism of binaural recording, the record can also be played and enjoyed on conventional stereo systems.
