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.
