AMPLIFIER FEATURE DESCRIPTIONS
POWERZONE AMPLIFIERS:
Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation except the mono amps
All Crunch amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit, and amplifier DC
faults indicated by the red “
PROTECT”
LED.
which are capable of 4, 2 and 1-Ohm loads.
CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE. YOU WILL CAUSE
The input sensitivities for rated output powers are variable from 0.2V to 5V on the multi channel amplifiers and 0.2V to

All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.
bridged. The mono amps are capable of 4, 2 and 1-Ohm.
A
POWER
LED indicates the powered up and turned on condition.
-The
LINE INPUT
signal is routed directly to the
LINE OUT
RCA jacks, regardless of the
X-OVER
setting simplifying daisy chaining of amplifiers.
-SUBSONIC:
Allows you to adjust the crossover filter from 15Hz to 55Hz.
-LOWPASS:
Allows yo to adjust the
LOW PASS
crossover filter from 40Hz to 150Hz.
LEVEL:
Adjusts the input sensitivity from 0.2 volts to 6 volts.
BASSBOOST:
45Hz bass boost adjustable from 0db to 12dB.
REMOTE CONTROL:
This is the input jack for the remote Level control.
LINE INPUT
: The line input accepts unbalanced (RCA) inputs from 0.2V to 6V.
LINE OUTPUT
: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
The mono amps are capable of 4, 2 & 1-Ohm loads.
Operating the amp below 1-Ohm can cause damage to the amp not covered in the warranty.
PZ1500.1 / PZ2500.1 MONO BLOCK AMPLIFIERS
The 4 channel amps have the same features as the 2 channel models accept that there are 2 sets of controls. 1 set for channels 1 & 2 and 1 set for channels 3 & 4.
In addition, the 4 channel models have a
Mode
switch which allows you to select 2, 3 or 4 operation. Switch to Mode 2 if you only have 1 set of RCA’s in CH 1/2 and the unit will
automatically supply signal to channels 3/4. Select Mode 3 when you only have RCA’s in CH 1/2 but plan to run channels 3/4 bridged. Select Mode 4 if you are providing
RCA’s to channels 1/2 and 3/4.
The
X-OVER
slide switch selects the internal crossover functions:
-The input signal is routed directly to the
LINE OUT
RCA jacks, regardless of the
X-OVER
setting simplifying daisy chaining of amplifiers.
-HPF:
Selects the built in
HIGH PASS
filter, variable from 60 Hz to 1.2kHz.
-FULL:
Bypasses all crossovers for full frequency range operation.
-LPF:
Selects the built in
LOW PASS
, variable from 30 Hz to 250Hz.
LINE INPUT
: The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT
: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
-BASS EQ:
Adjustable 45Hz bass boost from 0dB to 9dB.
Note that the LOW PASS signal is MONO.
-In the LPF position, the HIGH PASS filter acts as a subsonic filter.
-When the LPF mode is selected, a 0 to +9dB, at 45Hz, BASS -EQ is also switched in.
PZ900.4 / PZ1200.4 / PZ1800.4 / PZ3000.4 4-CHANNEL AMPLIFIERS
The
X-OVER

-The input signal is routed directly to the
LINE OUT
RCA jacks, regardless of the
X-OVER
setting simplifying daisy chaining of amplifiers.
-HPF:
Selects the built in

Selects the built in
LOW PASS
, variable from 30 Hz to 250Hz.
-BASS EQ:
Adjustable 45Hz bass boost from 0dB to 9dB.
MODE
: The mode switch allows you to choose Stereo for full range 2 channel operation or MONO for bridging operation
HIGH INPUT
: If your radio/CD player does not have unbalanced (RCA) outputs, you can use the HIGH level (wire) inputs.
LINE INPUT
: The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT
: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
Note that the LOW PASS signal is MONO.
-In the LPF position, the HIGH PASS filter acts as a subsonic filter.
-When the LPF mode is selected, a 0 to +9dB, at 45Hz, BASS -EQ is also switched in.
