ESIGN EATURES
1. Power/Protect LED – Power LED illuminates blue when the unit is turned on. Protect LED
illuminates red if a short circuit or to low of an impedance is detected at the speaker connections.The
amplifier will automatically shut down if this occurs.
2. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level input.
They are nickel-plated to resist the signal degradation caused by corrosion.
3. RCA Pass-Thru Jacks – This 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.
4. Gain Control – The input gain control is preset to match the output of most source units.
5. Infrasonic Filter – A variable 15-40Hz 12dB/octave filter designed to prevent frequencies below the
audio range from being applied to the subwoofer from the amplifier. Consequently improving subwoofer
performance and power handling, particularly in vented enclosures..
6. Variable Crossover (Low Pass Only) – Is a built-in 12dB/octave Butterworth filter with a
crossover point variable from 50Hz to 250Hz.
7. Punch EQ – This control is a narrow band adjustment variable from 0dB to +18dB @ 45Hz with a
Gyrator based Punch EQ that eliminates frequency shift with boost..
8. Remote Punch Level Control – When connected, the "Gain Control" is linked and allows you to
remotely control the output level of the amplifier from the dash or center console.
9. Speaker Terminals – The heavy duty, nickel-plated set screw wire connectors ( + and -) will
accommodate 8 AWG. Two Positive (+) and Negative (–) terminals are provided for
installation flexibility. Both terminals are wired in parallel internally. Only one
Positive (+) and one Negative (–) terminal is required for a speaker connection.
10. Power Terminals – The power and ground are nickel-plated set screw wire connectors and will
accommodate 4 AWG.
11. REM Terminal – The nickel-plated set screw wire connector and will accommodate 12 AWG.This
terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.
