AMPLIFIER FEATURE DESCRIPTION

Premium Multi-Channel Amplifiers

-Each model is capable of 4 & 2 ohms stereo per channel, or 4 ohms mono bridged operation.

-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 6 volt.

-All crossovers are fully variable in their respective ranges.

-Crossover filter slopes are 12 dB/octave for stereo filters, and 24 dB/octave for mono filters.

-A POWER LED indicates the powered “up” and turned “on” condi- tion.

- All MB QUART Premium amplifiers feature a comprehensive dia- gnostic system, with speaker lead short circuit, and amplifier DC faults indicated by the DIAGNOSTIC, or PROTECT LED.

CAUTION:

DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IM- PEDANCE. YOU WILL CAUSE DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE WARRANTY PRINTED IN THE BACK OF THE MANUAL.

PAB 2100 2-Channel Amplifier

MBQR-1

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 amplifier.

-HP: Selects the built in HIGH PASS filter, variable from 10 Hz to 150 Hz.

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

-LP: Selects the built in LOW PASS filter, variable from 30 Hz to 150 Hz.

Note that the LOW PASS signal is MONO.

-In the LP position, the HIGH PASS filter acts as a subsonic filter.

-When the LP mode is selected, a 0 to +9 dB, at 45 Hz, BASS EQ is also switched

PAB 4100 4-Channel Amplifier

MBQR-1

INPUT MODE slide switch:

-In the CH2 position, ALL four amplifier inputs are selected from the CH1/CH2 RCA jacks.

-In the 4CH position, channel pair 1&2 receive input signal from RCA jacks CH1 and CH2, and channel pair 3&4 receive input signal from RCA jacks CH3 and CH4.

The AMPLIFIER CH 1/2CH X-OVER slide switch selects the input

signal for channel pair 1&2:

-HP: Selects the built in HIGH PASS filter, variable from 10 Hz to 150 Hz.

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

-BP: Selects the built in LOW PASS filter, variable from 30 Hz to 150 Hz.

Note that the LOW PASS signal is MONO.

-In the BP position, the HIGH PASS filter acts as a subsonic filter.

-When the BP mode is selected, a 0 to +9 dB, at 45 Hz, BASS EQ is also switched in.

The AMPLIFIER CH 3/CH 4 X-OVER slide switch selects the input

signal for channel pair 3&4:

-Hi: Selects the built in HIGH PASS filter, variable from 10 Hz to 150 Hz.

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

-BP: Selects the built in LOW PASS filter, variable from 30 Hz to 150 Hz.

Note that the LOW PASS signal is MONO.

-In the BP position, the HIGH PASS filter acts as a subsonic filter.

-When the BP mode is selected, a 0 to +9 dB, at 45 Hz, BASS EQ is also switched in.

-Full range signal from channels 1/2 inputs are routed to the Line OUT RCA jacks, regardless of the setting of the X-OVER switches.

-The REMOTE jack enables dash mount level control of the LOW PASS signal, CH3/4 only.
