1.Cast Aluminum 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.

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

3.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.

4.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.

5.REM Terminal – This gold-plated spade terminal is used for the AP (auto power) or remote turn on of the Punch 250.1 Power amplifier.

6.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.

7.Summed Stereo / Mono Switch – This switch is used to select whether 1 or 2 signal inputs will be used to drive the amplifier.

8.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.

9.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.
