Gain Control Allows the nominal operating level of the amplifier to be set in conjunction
with the level of input voltage from the source unit. The D3 amplifiers will accommodate
low level (RCA) input ranging from 500 mV~5 V.
Bass Boost Acts like an equalizer with an adjustable gain fixed at 45 Hz. This adjustment
gives you up to 18 dB of boost at that frequency. This can be used to compensate for lack
of low-frequency response in the car audio environment.
Crossover Frequency Selection The crossover frequency is fully adjustable between
55 Hz and 550 Hz.
Crossover Mode Switch Switches crossover between off, low-pass, or high-pass.
When in the LP or HP position, a 12 dB per octave slope is implemented at the frequency
selected on the Frequency Knob.
Input Mode Switch Sets the input mode of the amplifier, depending on its purpose in the
system. Can be set to Stereo Mode, Bridged Mode, or Mono Mode.
Rear Channel Input Select (4 channel only) Allows channels 3 & 4 to use either set of
inputs (front or rear) for signal.
