NO OTHER RECEIVER OFFERS ALL THESE FEATURES. AND ONLY PIONEER OFFERS A WHOLE NEW ENGINEERING CONCEPT ON TOP OF ALL THESE FEATURES.
You'd expect a new receiver from the leading manufacturer of stereo receivers to be packed with exciting features. As you can see, it is But Pioneer didn't get to be No. 1 in receivers by doing the expected and stopping.
So we developed the SX-7 using a unique engineering concept we call High Fidelity for Humans. It makes the SX-7 as superb to live with as it is to listen to.
At the heart of the receiver is a micro-computer that's been programmed to operate controls electronically. It affords the owner of the SX-7 operating convenience unlike any previously available in conventional receiver designs.
For example, the microcomputer’s prodigious memory allows you to preset up to eight FM and eight AM stations and recall them instantly. Once set, all stations are directly accessible via "Station Call" but tons. And you can even recall them at the preprogrammed volume level because the microcomputer electronically controls volume setting.
What's more, with just the touch of a button you can search out the next station up (or down) the AM or FM tuning band. Stations are brought in perfectly tuned every time. And you can select any station by tuning it manually or scanning the entire band automatically sampling five seconds of each station.
But these human engineering features aren't all that make the SX-7 such an extraordinary receiver. It also offers features that have won Pioneer acclaim throughout the high fidelity industry.
Pioneer's engineers have designed an exclusive ID MOS FET transistor for the front end of the SX-7's tuner. It allows you to tune in stations with weaker signals with out worrying about stronger stations causing distortion due to front end overload. That's what keeps the SX-7 virtually free of RF intermodulation.
But no matter how free a receiver is from all forms of distortion, c must be able to keep the stat on you select perfectly tuned for hours. Pioneer's quartz-PLL digital synthesized Lining does this by making drift virtually impossible.
Pioneer's exclusive Non-switching amp also eliminates distortion caused by output transistors switching on and off thousands of times a second in response to music signals. This is one of the reasons that the total harmonic distortion of the SX-7 is no mere than 0.009% (continuous average power output of 60 watts per channel mini mum at 8 ohms, from 20Hz to 20,000Hz).
And Pioneer's high-gain phono preamp section allows the use of either MM or low output. MC cartridges selectable by a front panel switch. There's even a Subsonic filter you can use to do away with very low frequency interference caused by record warps.
NOW if you think all these features sound great in print, listen to them in person at your nearby Pioneer dealer. He'll demonstrate the SX-7 and an entire new line of Pioneer receivers. And you'll quickly see that done everything humanly possible to give you more music for your money.
That's what made Pioneer No.1 in receivers. And that's what's going to keep us there.
PIONEER--We bring it back alive.
------
INTRODUCING THE PIONEER SX-7 RECEIVER.
Computerized Push Button Controls: Pioneer has programmed a microcomputer
to operate controls electronically for improved accuracy, reliability and convenience.
Quartz PLL Digital Synthesized Tuning: FM "Drift" is eliminated by this incredibly accurate tuner.
Station Scan: Touch this control and you'll hear five seconds of every station
strong enough to meet the mute threshold.
Station Search: Touch this control and move to the next station up, or down, the band.
Subsonic Filter: This control lets you do away with ultra low frequency distortion caused by record warps and such.
Volume Memory: The SX-7 will also remember the volume you select for each preset station.
Eight AM presets, eight FM presets: The SX-7 will memorize eight of your
favorite FM and eight of your favorite AM stations and retrieve them instantly.
Non-Switching Amp: Pioneer's patented amp design gets rid of transistor switching distortion once and for all.
High-Gain Phono Preamp: Allows the use of either MM or low-output MC cartridges.
ID MOS FET Front End: This exclusive transistor circuitry tunes in weak stations
as clearly and quickly as strong stations.
