ESIGN

EATURES

Cast Aluminum Chrome Heatsink –

The cast aluminum heatsink of the Punch 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.

End Caps –

The unique end caps conceal the wiring and input cables, giving the amplifier a clean “stealth” look.

– 7 –

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.

Power Terminals –

The dual power and ground connectors on the Punch Power amplifier are gold-plated and will

accommodate up to two 8 AWG wires maximizing the input current capability of the amplifier.

REM Terminal –

This gold-plated spade terminal is used for the AP (auto power) or remote turn on of the Punch 250.

Power amplifier.

RCA Input Jacks –

The industry standard RCA jack provides an easy connection for signal level input. They are gold-

plated to resist the signal degradation caused by corrosion.

Summed Stereo / Mono Switch –

This switch is used to select whether 1 or 2 signal inputs will be used to drive the

amplifier.

Pass-Thru RCA Jacks –

The Pass-Thru provides a convenient source for daisychaining an additional amplifier.This

eliminates the need for additional RCA cables or “Y” adapters. The Pass-Thru output is Full Range only.

Input Sensitivity Control –

The input level 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.
