DESIGN FEATURES
INSTALLATION
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. Variable Crossover – The amplifiers have a built-in 12dB/octave Butterworth filter with a
crossover point variable from 50Hz to 210Hz. The crossover can be set to Low-Pass (LP) or it
can be bypassed by setting it to All-Pass (AP).
3. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level
input. They are gold-plated to resist the signal degradation caused by corrosion.
4. Gain Control – The input gain 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.
5. LED Power Indicator – The LED illuminates when the unit is turned on.
6. REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when
+12V DC is applied.
7. 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.
8.
High Level Inputs – The high level inputs use a detachable connector terminated with 20 AWG
leads. These inputs should be used if the source unit has only speaker line (high level) outputs
and not RCA outputs.
9. Punch Bass – The Punch Bass control helps correct for acoustical deficiencies in the listening
environment by helping produce full range sound without adding excessive boost.. The Punch
Bass control is a narrow band adjustment at 45Hz switchable from 0dB to +6dB to +12dB.
10. 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.
