Solid State Stereo Integrated Amplifier (1971-72)
The Pioneer SA-800 combines a modern control panel with luxurious cabinet styling in natural wood. Used together with other Pioneer Hi-Fi components, it presents an appearance of perfectly matched, systemized elegance.
The equalizer/head amplifier consists of three direct coupled stages, possessing high gain and, therefore, a wide dynamic range. Emitter to emitter feedback results in high stability and extremely accurate equalizing characteristics.
The power amplifier stage is a quasi complementary design with direct coupling, ie without coupling capacitors between the individual stages. This results in a super wide frequency response curve ranging from near DC to well above the audible sound range.
To maintain high output power with good stability, a positive negative symmetrical power supply unit is employed. These design features make the SA-800 power amp stage one of the world’s most advanced Hi-Fi amplifiers.
The SA-800 is equipped with terminals for a full range of program sources including two turntables, a tuner, two tape decks, microphone plus two auxiliary sources such as a cartridge tape player or TV sound track.
With two tape decks connected, duplicating and editing of recorded tapes becomes extremely easy.
The SA-800 incorporates a wide range of extra features which mark it as a truly advanced, versatile amplifier. These include a speaker selector which enables two sets of speakers to be used separately or together, a Pre and Main switch permitting independent use of the pre and power amplifier sections in a multi amp installation, an audio muting switch, a mode switch and a loudness switch.
