Inputs and Outputs
The amplifier is black with an MTX logo on top.
supply: The amplifier uses a patented PWM MOSFET switching power supply
with class A 100% Discrete Driver Circuit Topology (Preamp input is class A).
output: The gold plated RCA output provides a line level output. It is
used to drive an external amplifier. This is a full range output and is not
controlled by the unit's built in crossovers.
boost: Continuously adjustable and defeatable bass enhancement
circuitry (centered at 40Hz, rotary control for 0-18dB adjustment).
If you use the speaker level input on this unit and tie the
front L+ and L- speaker leads from a source unit with BTL outputs (most high
powered radios) the amplifier will turn on whenever there radio is turned on,
allowing for easy factory head unit integration.
amplifier has noiseless turn on-turn off..
controls: There is a variable rotary gain control.
boost: The bass boost is centered at 40Hz and may be adjusted from
frequency: The internal crossover is set at 85 Hz.
select switch: The crossover select switch allows you to select
whether the internal crossover functions as a full-range, low-pass, or high-pass
crossover. The crossover has a slope of 18 dB.
LED: When the power is on the LED lights red.
gold plated left and right RCA preamp inputs.
gold plated left and right RCA preamp outputs. This output is
gold plated +12V, Remote and Ground screw terminals.
gold plated Left and right screw terminal speaker outputs . To
bridge the amplifier you use the R(-) and L(+) terminals.
speaker level (high level) input is a Molex connection used with the
supplied wiring harness.
Power measured at 12.5 Volts DC:
x 2 into a 4 Ohm load with less than 0.5% THD
x 2 into a 2 Ohm load with less than 1% THD
x 1 into a 4 Ohm load with less than 1% THD
Power (IHF-202 Standard) measured at 14.4 Volts DC
x 2 into a 4 Ohm load
x 2 into a 2 Ohm load
x 1 into a 4 Ohm load
RMS power is given ONLY for 12.5 volts, so that is what is listed in the
Mounting hardware is NOT
INCLUDED. You will need four self-tapping screws to mount the unit,
wire for power, ground and remote turn on.
amplifier uses one 30 Amp ATC type fuses (blade)
