  • Notes

  • A hi-fi quadraphonic preamplifier housed in a wooden case, partner to the Pioneer QM-800 Quadraphonic Power Amplifier.  It provides a choice of two different four-channel effects, which are created from any existing two-channel stereo source (tape, phono or FM), as well as discrete four-channel stereo. It can also be used as a conventional two-channel stereo preamplifier.
