Powerone Amplifiers | Crunch P1-3050.1, P1-650.2, P1-1050.1, P1-650.4

AMPLIFIER FEATURE DESCRIPTIONS

POWERONE 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.

The input sensitivities for rated output powers are variable from 0.2V to 6V on all models. 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 and 1-Ohm.

LINE OUT LINE INPUT

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 12kHz.

-FULL: Bypasses all crossovers for full frequency range operation.

-LPF: 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 6V.

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 +12dB, at 45Hz, BASS -EQ is also switched in.

CHANNEL 3 / 4

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 or 4 channel operation. Switch to 2 channel 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 4 channel if you are providing RCA’s to channels 1/2 and 3/4.

The X-OVER slide switch selects the internal crossover functions:

-FULL: Bypasses all crossovers for full frequency range operation.

-LPF: Selects the built in LOW PASS , variable from 30 Hz to 250Hz.

-BASS EQ: Adjustable 45Hz bass boost from 0dB to 9dB.
