The SQ-200 was part of Sony's approach to decoding quadraphonic audio formats using the SQ matrix system. DESCRIPTION: Welcome to the world of the quadraphonic four-channel stereo sound. Stereo Quadraphonic sound adds depth to stereophonic sound because the sound is reproduced over four widely separated speakers, giving an impression of surround sound. With SQ sound, a symphony orchestra is not only displayed over the two front speakers as in conventional stereo, but its reverberant sounds are provided over back speakers, bringing actual concert hall presence to the listener. Also with this SQ system individual performers can be recorded to create new musical effects with the listener being completely enveloped by 360° sound; or, a performer can freely move around as in theatre or show recordings left, right, front or back. Quadraphonic sound reproduction is now possible with your present high fidelity music system by using the Sony decoder amplifier Model SQA-200 (which has an amplifier and also two output connectors for the back speakers) and two additional back speakers. When playing 4-channel SQ records, the special decoder in the SQA-200 provides reproduction of the original program on four separate channels. With the SQA-200 you can play SQ records on a conventional stereophonic player, and record and play back the SQ sound on a two channel tape recorder. Conventional stereophonic programs become more dynamic with outstanding front channel separation and back channel separation, and accurate positioning of each musical instrument.
