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.
