1. 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.
2. End Caps – Interchangeable 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 power and ground connectors on the
Punch amplifier are gold-plated and will accommodate up to 8
AWG wire maximizing the input current capability of the
amplifier.
5. REM Terminal – This spade terminal is used for the auto power/
remote turn-on of the Punch amplifier.
6. RCA Input Jacks – The industry standard RCA jacks provide easy
connections for signal level input. They are gold-plated to resist
the signal degradation caused by corrosion.
