LINE IN
Connect preamp signal cables from the source unit to these
terminals. Use of 2 or 4 channels of input signal selectable with
INPUT MODE switch.
INPUTS
Select Balanced or Unbalanced inputs based on your input
source's design for best S/N performance.
AUTO ON
Auto-on is useful when connecting to an OEM system that
does not offer a Remote turn-on lead to activate the amplifier.
When connecting directly to the amplifier using a high-level
input signal the circuit can detect the input voltage (BTL <1v
DC) and activate the amplifier. If your system has a standard
remote turn-on lead use the standard REM input. If it is an OEM
system that stays active even with the radio off (voltage on
signal wires) move the switch to the OFF position and

Use in conjunction with MODE switches. Selectable disabled

Select FLAT/HP/LP/BP then adjust to desired crossover point,
variable from 55Hz - 4kHz @ 12dB per octave. If LP or BP is
desired, move both switches to LP+LP or BP+BP. If Flat or HP
is selected, secondary LP/BP switch is disabled. Stereo (ST) or
Mono can also be selected for channels 3+4 depending on
application.

Peak output LED indicator for channels 3+4. Helpful when
used for subwoofer level adjustment. Adjust LEVEL so PEAK LED

output voltage is achieved.
REMOTE
Selecting LP for channels 3+4 activates this port. This port is for
connecting the (RBPC) remote bass level and phase controller
with BASS SHIFT . The unique feature of the RBPC with BASS
®
SHIFT® allows for perfect adjustment of not only the subwoofer
level but also 0-180° of phase adjustment from the listening
position. Properly adjusting phase will allow enhanced bass
response, dynamics and impact at any volume. To adjust, play
a test tone close to the crossover overlap you have the system
adjusted to, typically in the 50-100Hz range. With all system
speakers playing and at a moderate volume, slowly adjust
the phase dial on the RBPC across the entire range. When the
subwoofer is in phase with the other speakers in the system,
you should be able to detect a rise in volume, "the sweet
spot". Now return the control to the sweet spot and make small
adjustments +/- until you maximize the output. You have now
completed adjusting the phase and should not have to adjust
this again. Use the level control to adjust the subwoofer output
to your preference based on music program material.

locate an alternative circuit or PAC L.O.C. PRO device to activate the
amplifier. See Source Balanced/Unbalanced for High Level input wiring.
INPUT MODE
Input signal selectable for 2 or 4 channels. If only 2 channels of input
signal are available, select 2CH to allow signal to split to CH 3+4.
HP 1+2
Use in conjunction with MODE switch. Selectable disabled (FLAT) or
Highpass (HP). If HP is selected, then adjust dial to desired crossover
point, variable from 55Hz - 4kHz @ 12dB per octave.
LEVEL
Input sensitivity, used to properly match input signal levels from signal
source and maximize amplifier output while eliminating noise. Level is
not a volume control, level matching only. Adjust LEVEL to match source
output voltage. For reference, a typical aftermarket radio ranges from
2v-4v of output. At minimum, use of a multi-meter and test program
material is critical for this step. Independent level controls available for
channels 1+2 and 3+4.

SPEAKER
Speaker connections can be configured in Stereo (1 and 2 or 3 and
4), Mono (1+2 or 3+4) and 3 channel (1 and 2 , 3+4). Minimum speaker
impedance is 2Ω in Stereo or 4Ω Mono. When bridging the amplifier into

channels will be used.
RMD
RMD port is for connecting an optional Remote Monitoring Display
(RMD). The RMD allows real-time viewing of system voltage.
GND
This must be connected to the negative terminal of the car's battery or
bolted to a clean, unpainted part of the vehicle's chassis.
REM
This must be connected to switched +12V, usually a trigger wire coming
from the head unit or ignition.
If the system does not have a standard remote turn-on,
use of the AUTO ON feature may be useful.
BATT+
This must be connected to the positive terminal (+12V) of the car's
battery via a 50A fuse. The fuse must be located within 18 inches of
the battery. Use of 8ga or larger OFC (oxygen-free) copper wire is
recommended for best performance.
TRI-LIGHT
Tri-light LED amplifier status indicators will change colors according to an
array of system variables.
Blue - Standard Operation
Green - Over Voltage Warning/Thermal Protection
Amber - DC/Short Protection
Red - Internal Fuse Blown
OTM monitors amplifier internal temperatures, and if abnormal
temperatures are achieved, OTM will make minor adjustments to output
power to allow the amplifier to return to normal operating temperatures
without interruption.
