Controls and Inputs :
RCA Inputs - These RCA inputs are used with head units that have RCA or Line level outputs (head 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 - The gain control matches the input sensitivity of the amplifier to the head 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 head 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 head unit.
High Pass X-Over Switch - Used to turn on the active high-pass (HP) x-over on and off. When engaged (On) the x-over is "ON", when
disengaged (Off) the x-over is "OFF".
High Pass X-Over Frequency Control - Used to select the desired high-pass (HP) x-over frequency. The frequency is adjustable from
40Hz to 5000Hz (Ch1, Ch2). The frequency is adjustable from 40Hz to 800Hz (Ch3, Ch4).
Low Pass X-Over Switch - Turns the active low pass (LP) x-over on and off. When engaged (On) the x-over is "ON", when disengaged
(Off) the x-over is "OFF"
Low Pass X-Over Frequency Control - Used to select the desired low-pass (LP) x-over frequency. The frequency is adjustable from 800Hz
to 5000Hz (Ch3, Ch4). The frequency is adjustable from 40Hz to 800Hz (Ch5).
Band Pass X-Over : To use, turn "ON" the LP (3) and HP (5) x-overs at the same time, creating a band-pass x-over for kick woofers or
midranges. You can tune the filter with frequency controls (4) and (6).
Input Switch : If the head unit is equipped with 4 RCA outputs (2 front and 2 rear), use the ch-3 ch-4 mode and connect the 4 RCA
outputs to the ch-1 ch-2 ch-3 ch-4 RCA inputs on the amp. If only 2 RCA outputs are available from the head unit, use the ch-1 ch-2
mode and connect the RCA outputs to the ch-1 and ch-2 inputs of the amp.
Input Switch channel 5 : If the head unit is equipped with a dedicated subwoofer output, use the ch-5 mode connect the RCA from the
subwoofer output to the subwoofer ch-5 RCA inputs on the amp. If no dedicated subwoofer output is available from the headunit use
the ch1 - ch2 mode, the channel 5 will take the signal from ch-1 and ch-2 RCA inputs on the amp.
Phase switch - Used to match the bass from subwoofers and front speakers. Toggle the phase switch from 0° to 180°. Keep the loudest
bass response.
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.
