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 which are capable of 4, 2 and 1-Ohm loads.
Tri-Mode operation with any stereo pair of amplifier channels is possible, as with all bridgeable
amplifiers.
The input sensitivities for rated output powers are variable from 0.2 volt to 5 volt.
All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.
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.
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.
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 channel
operation.
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.
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.
-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.
-LPF: Allows yo to adjust the LOW PASS crossover filter from 40Hz to 150Hz.
MODE: The mode switch allows you to choose Stereo for full range 2 channel operation or MONO for
bridging operation
LEVEL: Adjusts the input sensitivity from 0.2 volts to 5 volts.
BASS EQ: The Bass EQ is adjustable from 0db to 12dB.
REMOTE: This is the input jack for the under-dash bass remote module.
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.

A POWER LED indicates the powered up and turned on condition.
All Crunch amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit,
and amplifier DC faults indicated by the red "PROTECT" LED.
CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE.. YOU
WILL CAUSE DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE
WARRANTY PRINTED IN THE BACK OF THE MANUAL. 2 & 4 Channel amps are capable of 4
and 2-Ohms wired stereo and 4-Ohms wired mono bridged. The mono amps are capable of 4, 2
