SX2 1200.1
MONOBLOCK POWER AMPLIFIER
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.
SPEAKER
Speaker connections are labeled +/- and will accept up to
10GA wire. Minimum speaker impedance is 1Ω.
RMD
RMD port is for connecting an optional Remote Monitoring
Display (RMD). The RMD allows real-time viewing of system
voltage.
MASTER / SLAVE
Linked mode is used when utilizing multiple amplifiers and
speakers with the desire to have them act in concert.
The Master amplifier will control all Slave amplifiers in this
configuration. Setting the Master amplifier will allow the
Slave amplifiers to become exact duplicates of the Master,
therefore making setup easy while having predictable results.

Repeat process for as many Slave amplifiers needed
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.
REMOTE
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 maybe useful.
BATT+
This must be connected to the positive terminal (+12V) of the car's
battery via a 80A fuse. The fuse must be located within 18 inches of
the battery. Use of 4GA 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
Red - Internal Fuse Blown
Amber - DC/Short Protection
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.
