Design Features
Variable Crossover
A built-in 12dB/octave Butterworth filter with a crossover
point variable from 50Hz to 250Hz. (R750-1D & R1200-1D
have an additional 12dB/octave Infrasonic filter with a cross-
over point variable from 15Hz to 40Hz SS)
Power/Protect LED
Power LED illuminates blue when the unit is turned on. Protect/
Thermal LED illuminates red when amplifier overheats or short
circuits. The amplifier will automatically shut down if this occurs.
Punch EQ - Variable
This variable control works along with the crossover
switch on the amplifier, boosting the bass frequencies.
Power/REM Terminals
The Power and Ground Terminals are nickel-plat-
ed set-screw wire connectors and will accommo-
date 4 AWG. The REM Terminal is a nickel-plated
set-screw wire connector and will accommodate
8 AWG.

RCA Input/Pass-Thru Jacks
The RCA Inputs/Pass-Thru Jacks are nickel-plated to resist the signal degradation
caused by corrosion. The Pass-Thru provides a convenient source for daisy-chaining
an additional amplifier without running an extra set of RCA cables from the front of the
vehicle to the rear amplifier location.
