The Pioneer SX-850 is a high power AM/FM stereo receiver with super-quiet phono equalizer and outstanding FM selectivity/sensitivity.
How do you know when to trust a stereo receiver to fill your musical needs? Power output by itself is not much help, because unless your listening room is the size of a concert hall, a receiver with far less than concert-hall-sized output will do nicely. The answer, obviously, is to put your trust in the circuitry the kind that you’ll enjoy in the pioneer SX-850. It delivers a continuous power output of 65 watts per channel, min RMS at 8 ohms, from 20 to 20,000 Hertz, with no more than 0.1% total harmonic distortion. But even more importantly, it has the strength and finesse to handle that power with a healthy respect for musicality. The SX-850 has a super-quiet phono equalizer in a 3-stage direct-coupled design to achieve wide dynamic range and +- 0.2dB RIAA equalization accuracy. A FET in the Tone Control section, plus a 2-step frequency turnover switch for Bass and another for Treble, 2-deck monitor/dubbing, 2-system speaker drive, separable pre/main and more, mean further control versatility. The superb FM/ AM section uses a dual-gate MOS FET and a 4-gang variable capacitor to boost sensitivity and selectivity, a PLL IC in the multiplex to improve stereo separation, and a special Integrated Circuit in the AM for still better reception and less noise. It’s the Pioneer SX-850 - the one you can trust to keep faith with your musical needs.
