1. 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.
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 50.
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. Balanced Line Input– This input will allow the balanced inputs to be used in conjunction with the Punch 50.
amplifier to provide better noise rejection.
8. Signal Input Switch – This switch allows selection of either the RCA or Balanced Line inputs.
9. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisychaining an additional amplifier. This
eliminates the need for additional RCA cables or "Y" adapters. One of the internal crossovers can be designated to
the Pass Thru output creating a dedicated low-pass, high-pass, or full range output.
