Maxxsonics PZI1500.1 Powerzone Amplifiers, PZi100.2 / PZi250.2 / PZi325.2 2-CHANNEL Amplifiers

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.

!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

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.

LINE INPUT: Accepts unbalanced RCA inputs from 0.2 volts to 9 volts.

LINE OUTPUT: The unbalanced RCA outputs are set the same as the CROSSOVER switch on the side mount control.

BALANCED INPUT: Accepts balanced line inputs from 0.4 volts to 12 volts for the optional MMBLD- 1 balanced line driver.

LEVEL: The input level control allows you to match the amplifier input sensitivity to the output level of the RADIO/CD source from 0.2 volts to 9 volts when using unbalanced (RCA) and 0.2 volts to 18 volts with the balanced input.

PHASE: The Phase shift is fully adjustable from 0 to 180 degrees.

REMOTE: The RJ45 Remote jack accepts the Bass Remote Module.

BASS EQ: The Bass Boost is fully adjustable from 0 to 10db at 45Hz.

SUBSONIC: The variable Subsonic filter is fully adjustable from 15Hz to 35Hz.

LOWPASS: The built-in low pass frequencies are fully variable from 35 to 250Hz.

POWER: Indicates that the amp has power, ground and remote turn-on input via a green L.E.D.

PROTECT: Indicates that the amplifier has detected a fault and will not operate. There are several possible problems that can cause the amplifier to go into the protect mode. See the trouble shooting guide in the back of the manual for details.
