Power Terminal (+12V) : This is the main power input for the amplifier and must be connected directly to the positive terminal of the
vehicles battery for proper operation. Use caution when installing (+12V) power cable in the vehicle. Avoid running this cable parallel
with RCA cables, antennas, or other sensitive equipment due to massive currents that can induce noise into the audio system. It is
also very important to have a tight, secure connection for maximum performance. MTX recommends using a minimum of 6mm2 full
copper power wire with the MTX RTP12x2.
Remote Terminal (REM) : The amplifier can be turned on by applying 12 volts to this terminal. Typically this voltage is supplied by a wire
from the source unit marked "remote" or "power antenna".
Ground Terminal (GND) : A proper ground is required for your amplifier to operate at peak performance. A short ground cable the same
diameter as the power cable should be used to attach the ground terminal directly to the chassis of the vehicle. Always remove paint,
dirt or debris to expose bare metal where the ground will be attached.
Protection LED (Prot.) : When the amp is in thermal protection, the LED turns to red.
PowerOn LED (PWR.) : The LED illuminates red when the amp is switched on.
RCA Inputs (Input) : These RCA inputs are used with source units that have RCA or Line level outputs. (Source units need a minimum
level of 200mV output for proper operation of the amplifier). MTX recommends only high quality RCA cables to decrease the possibility
of radiated noise entering the system.
Gain Control (Gain) : The gain control matches the input sensitivity of the amplifier to the source unit being used.
The operating range varies from 200mv to 6V. Adjusting the gain:
1. Turn the gain control on the amplifier all the way down (counter clockwise).
2. Turn up the volume control on the source unit to approximately 3⁄4 of maximum.
3. Adjust the gain control on the amplifier until audible distortion occurs.
4. Adjust the gain control down until audible distortion disappears.
5. The amplifier is now calibrated to the output of the source unit.
Speaker level inputs (High Level Input) : This input will allow the amplifier to operate from source units with speaker-level outputs.
Output speaker leads from the source unit should be tied directly to the wire harness provided with the amplifier.
Note : When speaker level inputs are used, a remote turn on wire must used to switch the amplifier on and off.
Remote bass control port (EBC) : use this port to connect the optional MTX EBC. It alows you to control the output level siting at the
front of the car.
