Overview: The MTX Thunder75.4 is a full range 4-channel
amplifier. It has aluminum heatsinks to dissipate heat generated by the amplifier.
The amp produces 75 watts RMS x 4 at 4Ω, 100 watts RMS x 4 at 2Ω, and
200 watts RMS x 2 bridged at 4Ω.
Gain: The amp's front and rear channel rotary gain controls
are independent and continuously variable from 200mV to 5V to match the output
of the source unit.
Protection Circuits: The Thunder75.4 provides protection
against overheating, under voltage, and electrical short circuits.
Crossovers: The front and rear channels have independent
- Front: high-pass; continuously variable
from 10 Hz (full range) to 200 Hz
- Rear: switchable between low-pass, full
range, and high-pass; the crossover point (high-pass or low-pass)
is continuously variable from 50 Hz to 750 Hz
Power Terminals: The Thunder75.4 features set screw terminals for
power, ground and remote turn-on. The power and ground terminals will accommodate up
to 4 AWG wire, while the remote turn-on terminal will accept up to 10 AWG wire. The
set screws are loosened/tightened with the supplied Allen wrenches. MTX recommends
the use of 4 AWG power and ground wires.
Note: The Amplifier is not equipped with
an internal fuse. An external 60-amp fuse (not included)
must be installed on the power wire. If the system has only
this amp and a wiring kit is used that includes a fuse with
a value other than 60-amps, the original should be replaced
with a 60-amp fuse.
Speaker Connections: The amplifier is equipped with four pair
of set screw terminal speaker outputs. Each terminal will accommodate up to 10 AWG
bare wire and is loosened/tightened with the supplied Allen wrench.
