1.LED Power Indicator – The LED illuminates when the unit is turned on.

2.REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.

3.Power Terminals – The power and ground connectors on the amplifier are gold-plated and will accommodate up to 4 AWG wire maximizing the input current capability of the amplifier.

4.Speaker Terminals – The heavy duty, gold-plated terminal block connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG. These gold-plated connectors are immune to corrosion that can cause signal deterioration.

5.Cast Aluminum Heatsink – The cast aluminum heatsink of the Power amplifier dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

6.Variable Crossover – The amplifiers have a built-in 24dB/octave Butterworth filter selectable for High-Pass (HP), All Pass (AP), or Low-Pass (LP) operation variable from 50Hz to 250Hz.

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

8.Punch Bass – The Punch Bass control helps correct for acoustical deficiencies in the listening environment by helping produce full range sound without adding excessive boost.. The Punch Bass control is a narrow band adjustment at 45Hz variable from 0dB to + 18dB. Connection is made with a cable using RJ-45 and can be installed under the dash for remote control access.

9.Signal Input Switch – This switch allows the amplifier to be driven with either 2 or 4 pairs of inputs.

10.Gain Control – The input gain control is preset to match the output of most source units. It can be adjusted to match output levels from a variety of source units.

11.RCA Pass-Thru Jacks – 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.
