HCA-1206 Six Channel Power Amplifier.
Rear panel switches for center channel - small, large, and none.
Signal processing options include Dolby Pro Logic, Stadium, Hall, and Club. Looping switches feed input signal to additional channels. Long known for the high quality of their preamplifiers and power amplifiers, Parasound has entered the home theater market as a major contender with this electronic component. One of the drawbacks of using a surround processor that is not integrated with the power amplifiers is that you need five interconnect cables. This can not only be expensive, but it creates a literal telephone exchange-look to the backside of the equipment rack.
