From Pioneer:

Not all high fidelity situations require high powered equipment.

If your listening room is of average size, and what you really want is more efficiency and more sophisticated versatility in a medium-powered model, Pioneer's new SX-636 will be a good choice.

It incorporates the latest state-of-the-art advantages for superior high fidelity performance. But it saves you money and doesn't waste watts.

The FM tuner employs a low-noise FET and a frequency-linear 3-gang variable capacitor in the front end. The FM IF section features a 5-stage limiter of high-performance IC and phase-linear ceramic filters. And to ensure stability under all operating conditions, the FM MPX circuit is the advanced PLL (Phase-Lock-Loop) type with an IC.

FM results are impressive: 1.9pV (IHF) sensitivity, capture ratio of 1.0dB (IHF), 60dB selectivity (IHF), signal-to-noise ratio of 70dB and wide separation of more than 30dB over the 50 to 10,000Hz range.

Accurate high fidelity reproduction is achieved with a particularly precise phono equalizer in the Pioneer SX-636. It keeps RIAA deviation within +- 0.5dB.

And as for power, the advanced direct-coupled OCL power amplifier provides continuous power output of 25 watts per channel, min RMS at 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.5% total harmonic distortion.

This is enough to drive up to two pairs of stereo speaker systems independently or simultaneously with brilliant, high fidelity results.

As a stereo control center the SX-636 is up to the minute - there are two stereo pairs of tape terminals (deck 1 to deck 2 tape duplication is possible), a function switch to handle FM, AM PHONO, MIC and AUX. An FM-linear dial scale with dual meter tuning system, illuminated program indicators, a stereo headphone jack and other conveniences add to the versatility.

The efficient Pioneer SX-636 puts stereo power in its place - with no wasted watts or wasted money for your stereo pleasure.
