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 cable

will be attached.

Remote Terminal (REM) - The ampliﬁer can be turned on by applying 12 volts to this terminal. Typically this voltage is supplied by a wire from the source unit marked

“remote” or “power antenna”.

+12V Power Terminal (12V) - 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 connection for maximum performance. MTX

recommends using 50mm

2 power wire with the MTX RFL4001D ampliﬁer.

Speaker Terminals TX81000D TX6500D (Sub outputs) : Connect your subwoofer(s) to these terminals. If using two subwoofers or a dual voice coil subwoofer, respect

the phase (+) together, (-) together...

Speaker Terminals TX480D : Connect the 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 Ch1 positive terminal and the Ch2 negative terminal only.

When bridging the ampliﬁer, use the Ch3 positive terminal and the Ch4 negative terminal only.

Warning : do not bridge the ampliﬁer with an impedance lower than 4Ω.

RCA Inputs (Ch.1 Ch.2 Ch.3 Ch.4) - 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 (Gain) - The gain control matches the input sensitivity of the ampliﬁer to the head unit being used. The operating range varies from 0,2 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 (Subsonic) - 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.

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 (Data Link) : Used to connect two TX81000D or two TX6500D in bridge mode and used in Master/Slave mode. The RJ15 cable is included. For more

detail see Master/Slave mode section.

12V thermoregulated fan connector for one or two 12V external cooling fans (Attention : 0,5A max - two fans max). The harness is included.

High 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. Please respect the polarity to get the maximum sound quality.

Note : When speaker level inputs are used, a remote turn on wire must be used to switch the ampliﬁer on and oﬀ.

X-Over Switch (X-Over) :

In “LP” position, the active low pass (LP) x-over is turned on. Use this position for subwoofer application.

In “HP” position, the active high pass (HP) x-over is turned on. Use this position for speaker application.

In “Oﬀ” position, the x-over is turned oﬀ. The amp is in wide range mode.

X-Over Frequency Control (Frequency) : Used to select the desired x-over frequency. The frequency is adjustable from 0Hz to 400Hz.

PowerOn/Protection LED :

1. The LED illuminates red when the amp is switched on.

2. The LED is ﬂashing red when the outputs are is in short circuit, when the impedance is too low (2Ω minimum), when the amp is in thermal protection .
