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.
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.
