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 100mv 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.
Low-Pass High-Pass X-Over Switch (X-OVER) :
In “LPF” position, the active low pass (LP) x-over is turned on
In “HPF” position, the active high pass (HP) x-over is turned on
In “FULL” position, the x-over is turned off
High Pass X-Over Frequency Control (HPF) :
Used to select the desired high-pass (HP) x-over frequency. The frequency is adjustable from 40Hz to 400Hz..
Low Pass X-Over Frequency Control (LPF) :
Used to select the desired low-pass (LP) x-over frequency. The frequency is adjustable from 40Hz to 400Hz..
RCA Inputs (LOW 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.
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.
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.
(+12V) Power Terminal : 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 con-
nection for maximum performance. MTX recommends using 10mm 2 power wire with the MTX RT60.4 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 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.
Speaker Terminals (SPEAKER) : 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.
Bridge Mode : When bridging the amplifier, use the right positive terminal and the left negative terminal only.
Warning : do not bridge the amplifier with an impedance lower than 4 ohm.
Fuse (FUSE) : When fuse blow, replace them with the same value. Never use a higher rated fuse !
Caution : fuses are located under the amp.
