DESIGN FEATURES

Power

Connections

1.LED Power Indicator (Top of unit) – 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 platinum-plated and will accommodate up to 8 AWG wire maximizing the input current capability of the amplifier.

4.Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch 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.

5.Punch Bass – 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.

6.Variable Crossover – Is a built-in 12dB/octave Butterworth filter selectable for High-Pass (HP), All Pass (AP), or Low-Pass (LP) operation variable from 50Hz to 250Hz.

7.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.

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

9.High Level Inputs – The high level inputs use a detachable connector terminated with 20 AWG leads. These inputs should be used if the source unit has only speaker line (high level) outputs and not RCA outputs.

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