Speaker terminals accept up to AWG #12 speaker wir e[...]

signal sour ces Due to the wide input level adjustment range, all a/d/s/ PowerPlates™ can be driven with either a conventional preamplifier drive signal or the amplifier signal fr om a powered sour ce unit. This makes the PowerPlate™ perfect for upgrading an OEM (Original Equipment Manufacturer) ster eo system while retaining the factory instal[...]

inter nal signal r outing 2-channel/4-channel input switch - routes RCA input fr om channels 1/2 to channels 3/4. When the switch is engaged, channel 1 input is routed to both amplifier channels 1 and 3 with input channel 2 routed to amplifier channels 2 and 4. Switch in the engaged position. When the switch is disengaged, channels 1, 2, 3, and 4 r[...]
