DESIGN FEATURES

Controls

1.Gain Adjuster – These can be adjusted to match output levels from a variety of source units individually for the left and right inputs.

2.Crossover Multiplier Range Switch – Used to set the multiplier for the left and right crossover frequencies between x1 and x10. A setting of x1 leaves the adjustable crossover frequency from 50-500Hz. A setting of x10 changes the adjustable crossover frequency to 500-5KHz (5000Hz)

3.Crossover Frequency Adjuster– Used to adjust the left and right crossover frequency. Variable from 50Hz to 500Hz in x1 mode, and 500-5KHz in x10 mode.

4.Crossover Type – Is used for selecting High-Pass Filter (HPF) or Low-Pass Filter (LPF) operation for the left and right speaker outputs.

5.Crossover Filter Switch – Off sets the crossover to all-pass, adjustments to the crossover range, freq, and type are bypassed. On allows adjustments to the crossover settings to be used.

6.Front End Defeat – Used to reroute the input signal around the signal processing circuitry within the amplifier. While in the ON position, all gain and crossover functions are bypassed.

7.Clipping LED Indicators – These Yellow LEDs illuminate if clipping is detected for either the left or right speaker outputs.

8.Power LED – This Green LED illuminates when the unit is turned on.

9.Protect LED – This Red LED illuminates if a short circuit or too low of an impedance is detected at the speaker connections or if the amplifier reaches thermal protection. The amplifier will automatically shut down if this occurs.

DESIGN FEATURES

Connections

Left Side

Right Side

1.RCA Line Output Jacks – These outputs provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle. These are pass-thru only and are not effected by crossover or gain adjustments.

2.RCA Input Jacks – The industry standard RCA jacks provide an easy connection for line level input. They are plated to resist the signal degradation caused by corrosion.

3.Speaker Plug Receptacle – Receptacle for the speaker plug connector. These connectors (+ and –) will accept wire sizes from 12 AWG to 18 AWG.

4.Fuses – These ATC fuses are easily accessible in case of failure. Always replace fuses with same type and rating. See Specifications for fuse ratings.

5.Power Plug Receptacle – Receptacle for the power plug connector. The power (+12V DC) and ground wire connectors will accommodate up to a 2 AWG wire. The Remote wire connector will accommodate sizes from 12 AWG to 18 AWG. The Remote terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.
