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.
Subsonic Switch - Used to switch the subsonic filter on or off. The subsonic filter frequency is set to 20Hz. The subsonic filter protects
subwoofer(s) against low frequencies that can cause damage. Very useful with vented enclosures.
Low Pass X-Over Frequency Control - Used to select the desired low-pass (LP) x-over frequency. The frequency is adjustable from
40Hz to 150Hz.
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.
Bridge mode Switch - Used to put the amp in Master mode or Slave mode when bridging two RFL4001D's. For more details, see Master/
Slave Mode section.
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.
Data link Port - Used to connect two RFL4001D's when used in Master/Slave mode. The RJ15 cable is included. For more detail see
Master/Slave mode section.
