Control Panel :
ISO power connector (Power Input) : Use the included extension cord and your headunit ISO power connector
to feed the amp. The power supply is wired in parrallel with your head unit. You don't need to cut any wire dur-
ing installation.
Speaker output on ISO connector (Speaker output) : These are the speaker outputs to be connected to the car
speakers. Connect the car ISO speaker connector here. You can use the included extension cord if needed.
Speaker high level input on ISO connector (High Level Input) : This is the high level speaker input to be con-
nected to the car radio.
You can use the included extension cord if needed.
PowerOn/Protection LED - The LEDs illuminate red when the amp is switched on. When the amps is in short
circuit, low impedance or thermal protection, the LEDs are blinking.
Remote switch (Remote) : Allows you to choose between the usual wired remote ("Cable" position when using
the remote from in power connector) or automatic remote (Auto position). If a remote wire is available behind
your head unit, it is better to use it.
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.
RCA Inputs connector (RCA Inputs) : 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. A wire harness is included in the
box. MTX recommends only high quality twisted pair cables (such as StreetWires) to decrease the possibility of
radiated noise entering the system.
