DESIGN FEATURES
1. LED Power Indicator (Top of unit) – The LED illuminates when the unit is turned on.
2. REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when
+12V DC is applied.
3. Power Terminals – The power and ground connectors on the amplifier are platinum-plated and
will accommodate up to 8 AWG wire maximizing the input current capability of the amplifier.
4. Speaker Terminals – The heavy duty, platinum-plated terminal block connectors (+ and –) will
accept wire sizes from 8 AWG to 18 AWG. These platinum-plated connectors are immune to
corrosion that can cause signal deterioration.
5. 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.
6. 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.
7.
Internal Crossover (Models 301X & 501X) – Is a built-in 24dB/octave Butterworth filter
selectable between 120Hz High-Pass (HP), All Pass (AP), or 80Hz Low-Pass (LP) operation.
7.
Variable Crossover (Model 801X) – Is a built-in 24dB/octave Butterworth filter selectable for
High-Pass (HP), All Pass (AP), or Low-Pass (LP) operation variable from 50Hz to 250Hz.
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.
