1.
Power LED (Top of unit - Not Shown) – This Blue LED illuminates when the unit is turned on.
2.
Thermal LED (Top of unit - Not Shown) – This Red LED illuminates if the amplifier internal
components become too hot and engage the thermal protection.The amplifier will shut down to cool
if this occurs.
3.
Protect LED (Top of unit - Not Shown) – This Yellow LED illuminates if a short circuit or too low
of an impedance is detected at the speaker connections.The amplifier will automatically shut down if
this occurs.
4.
Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch amplifier dissipates heat
generated by the amplifier's circuitry.
5.
Speaker Terminals – The heavy duty, nickel-plated clamp wire connectors ( + and -) will accept wire
sizes from 8 AWG to 18 AWG.
6.
Remote Punch EQ (Optional Controller) – The Remote Punch EQ connection is made with a RJ-45
cable and can be installed in a variety of ways for easy control access.The control is used to boost low
and/or high frequency information to overcome road noise.The remote overrides the Punch EQ on the
amplifier when connected.
NOTE:Previous (prior to 2007) Punch Bass and Para-Punch remotes will not work with these amplifiers.
7.
Punch EQ (P300-1 Only) – A Gyrator based Punch EQ that eliminates frequency shift with boost.This
works along with the crossover switch on the amplifier.When set to Low-Pass (LP) operation, this is a
variable Bass Boost (P1000-1bd). When set to High-Pass (HP) operation, this is a variable Mid-Bass and
Treble Boost. When set to All Pass (AP) operation, both the Bass and Treble frequencies are boosted.
7.
Punch EQ (P500-1bd & P1000-1bd Only) – This control is a narrow band adjustment variable from
0dB to +18dB @ 45Hz with a Gyrator based Punch EQ that eliminates frequency shift with boost.
8.
Crossover Switch (P300-1 Only) – Selectable switch for High-Pass (HP),All Pass (AP), or Low-Pass
(LP) operation.
9.
Variable Crossover (P300-1 Only) – Is a built-in 12dB/octave Butterworth filter with a crossover
point variable from 50Hz to 500Hz.
9.
Variable Crossover (P500-1bd & P1000-1bd Only) – Is a built-in 12dB/octave Butterworth filter
with a crossover point variable from 35Hz to 250Hz.The crossover is set to Low-Pass (LP).
10. 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.
11. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level input.
They are nickel-plated to resist the signal degradation caused by corrosion.
