Owner’s Manual - TH1500D

Speaker Terminals - Connect subwoofer(s) to these terminals. If using two subwoofers or a dual voice coil sub-

woofer, respect the phase.

Attention : The two (+) connectors are wired parallel internally. Same for the two (-) connectors.

Thermal Protection - This LED illuminates red when the amp reaches 100°C. The LED also turns red when the

power supply goes below 9V or over 16.2V.

Short Circuit Protection - This LED will ash yellow when the speaker outputs will short circuit. Without signal,

this LED can remain yellow when the speaker outputs are short circuited.

Fuses - When fuses blow, replace them with the same value. Never use a higher rated fuse !

(+12) Power Terminal - This is the main power input for the amplier and must be connected directly to the posi-

tive 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

power wire with the MTX TH1500D amplier.

Remote Terminal – The amplier 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".

Ground Terminal – A proper ground is required for your amplier 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 will be attached.

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.

Master/Slave Switch - Used to put the amp in Master mode or Slave mode when bridging two TH1500D's. For

more details, see Master/Slave Mode section below.

Master/Slave Port - Used to connect two TH1500D when used in Master/Slave mode. The RJ15 cable is included.

For more detail see Master/Slave mode section below.

Master Slave Mode

For MAXIMUM output power, two TH1500D amps can be bridged together.

1. Decide which TH1500D is the "Master" amp. The other one will be the "Slave" amp. Set the "Bridge Mode"

switch (16) to "Master" on the master amp. Set the slave amp to "Slave" (16).

2. Connect the input signal from the source unit to the RCA inputs of the master amp. The slave amp doesn't

need RCA connection. It will take the signal from the master amp through the RJ15 cable.

3. Connect the included RJ15 cable to both amps.

4. Adjust the gain, x-over, subsonic lter and phase on the master amp. All slave amp controls are disconnected

through slave mode. The master amp fully manages the slave amp.

5. Your (+) speaker output is the (+) speaker output from the master amp.

6. Your (-) speaker output is the (+) speaker output from the slave amp.

Note: The EBC remote works ne in master/slave mode. It only needs to be connected it to the master amp.
