8 REAR Remote Input
This remote input is parallel to the FRONT remote input and does not need to be connected for the amplifier to operate. Use either remote input to turn the amplifier on. Do not connect 12V accessories to this input.
9 REAR Input Switch
In the left position, the L & R inputs go to the REAR L & R channels of the ampli- fier. In the right (MONO) position, the inputs are summed. Use this setting when the REAR channels are used with a subwoofer.
10REAR Crossover Controls
To use highpass 12dB/octave crossover, move left switch to upper position. To use lowpass 12dB/octave crossover, move left switch to lower position. Highpass and lowpass crossover frequencies are adjustable from 50Hz to 350Hz by rotary control. Move filter switch to “ON” position to engage.
11Status LED Indicators
GREEN indicates the normal operating condition; the amplifier is “ON.” GREEN and RED together are normal when the amplifier is first turned “ON”; RED will turn off after a few seconds. When both GREEN and RED remain on, the ampli- fier is in thermal shutdown condition. RED only indicates a fault condition, “SAFE.”
