Amplifier Owner’s Manual
INPUT
Connect preamp signal cables from the head unit to these terminals.
OUTPUT
Provides a full range signal for an additional amplifier. There is no signal
loss if using this output.
CROSSOVER FREQUENCY
Controls the lowpass crossover point for the speaker outputs.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45 Hz.
LOW PASS LEVEL CONTROL (LPL)
This port is for connecting the optional remote level control (LPL44). This
allows up to 20dB of volume adjustment. This is not a bass boost, it
controls the level of the low pass signal.
REMOTE MONITORING DISPLAY (RMD)
Connect optional RMD Voltage Display to this port
LEVEL
Used to reach maximum amplifier power with a wide variety of headunits.
SUBSONIC CROSSOVER FREQUENCY
Controls the highpass crossover point for the speaker outputs to eliminate extreme
low frequencies.
PEAK INDICATOR
Lights when the amplifier reaches near maximum output. Under normal
operation the peak indicator should be flashing during the peaks of the
music. Peak indicator should not stay lit for long periods of time (more
than 2 or 3 seconds), if this is the case you need to reduce system volume
or level of the amplifier.
PROTECT INDICATOR
Lights red if there is a problem with the audio system. For example, speaker wire is
pinched/shorted together or the amplifier is running too low of an impedance.
12V+
This must be connected to the fused positive terminal (+12V) of the car’s
battery. The fuse must be located within 18 inches of the battery.
REMOTE
This must be connected to sw12V, usually a trigger wire coming
from the head unit or ignition.
GND
This must be connected to the negative terminal of the car’s battery or
bolted to a clean, unpainted part of the chassis of the vehicle.
SPEAKER OUTPUTS
Used to connect the amplifier to speakers. Minimum impedance is 1 ohm.
