1.Power LED –This LED illuminates when the unit is turned on.
2.Protect LED –This LED illuminates 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.
3.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.
4.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.
5.Gain Control – The input gain control is preset to match the output of most source units.
6.Phase Switch – Allows you to select the output phase of the amplifier between 0° and 180°.
7.Variable Crossover (Low Pass Only) – Is a built-in 12dB/octave Butterworth filter with a crossover point variable from 40Hz to 130Hz.
8.Punch Bass – This is an adjustable Bass level control centered at 45Hz @ 12dB/octave.
9.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.
10.Power Terminals –The power and ground are nickel-plated clamp wire connectors and will accommodate 4 AWG #8 (up to 1/2”) spade or ring style connectors.
11.REM Terminal – The nickel-plated clamp wire connector and will accommodate 8 AWG #8 (up to 3/8”) spade or ring style connectors.This terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.
12.Fuses – These ATC fuses are easily accessible in case of failure.Always replace fuses with same type and rating. See Specifications for fuse ratings.
13.Speaker Terminals – The heavy duty,nickel-plated clamp wire connectors (+ and -) will accommodate
8 AWG #8 (up to 3/8”) spade or ring style connectors. 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.
