Control Panel on the Amplier
Owner’s Manual - RT8PT
Speaker level inputs - This input will allow the amplier 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 amplier.
Note : When speaker level inputs are used, a remote turn on wire must used to switch the amplier on and o.
EBC Port (External Bass Control) - The Remote Subwoofer Level Control (EBC) plugs directly into this port, while
the EBC itself can be placed anywhere in the vehicle for on demand bass adjustments. EBC is included.
RCA Inputs - 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 amplier).
MTX recommends only high quality twisted pair cables (such as StreetWires) to decrease the possibility of radi-
ated noise entering the system.
Gain Control - The gain control matches the input sensitivity of the amplier to the source unit being used. The
operating range varies from 100mv to 6V.
Adjusting the gain
1. Turn the gain control on the amplier 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 amplier until audible distortion occurs.
4. Adjust the gain control down until audible distortion disappears.
5. The amplier is now calibrated to the output of the source unit.
Low Pass X-Over Frequency Control - Used to select the desired low-pass (LP) x-over frequency. The frequency is
adjustable from 50Hz to 200Hz..
Protection LED - When the amps is in thermal protection, the LED turns to red.
PowerOn LED - The LED illuminates red when the amp is switched on.
