Control Panel
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.
X-Over Switch (X-Over) :
In “LP” position, the active low pass (LP) x-over is turned on. Use this position for subwoofer application.
In “HP” position, the active high pass (HP) x-over is turned on. Use this position for speakers application.
In “Off” position, the x-over is turned off (wide range)
Phase switch (Phase) : Used to match the bass from subwoofers and front speakers. Toggle the phase switch
from 0° to 180°. Keep the loudest bass response.
Remote 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.
Note : The EBC remote works only when the low pass xover is active (switch in LPF position).
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 100mV output for proper operation of the amplifier).
MTX recommends only high quality twisted pair cables (such as StreetWires) to decrease the possibility of radi-
ated noise entering the system.
RCA outputs (Output) : These RCA output jacks are for connecting multiple amplifiers to 1 stereo RCA lead com-
ing from the source unit (daisy chaining).
PowerOn/Protection LED : The LED illuminates red when the amp is switched on. When the amps is in shortcir-
cuit or thermal protection, the LED is blinking. You need to switch off and on the amp to restart.
Speaker level inputs (HLI) : 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.
Speaker Terminals (Sub/Spk (+) Sub/Spk (-)) : Connect speakers to these terminals. Observe speaker polarity
throughout the system. Improper phase can result in loss of bass response and/or poor overall sound quality.
Fuse (40A) : When fuse blow, replace it with the same value (40A). Never use a higher rated fuse !
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 (+12) 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 10mm
2
power wire with the MTX TR600.1
amplifier.
Remote Terminal (REM) : The amplifier can be turned on by applying 12 volts to this terminal. Typically this volt-
age 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 must 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.
