AMPLIFIER APPLICATIONS PAB 2100 2-Channel Amplifi er

MBQR-1

Full range stereo

This is the most basic application for the Premium Series 2 channel 

amplifi ers.

1. Interconnect cable checklist: 

Connect the LINE INPUTS to the Radio/CD with good quality RCA 

cables.

2. Crossover Switch:

The X-OVER switch must be in the FULL position.

3. Crossover frequency control checklist:

N/A for full range operation.

4. Line Level:

Refer to the section “Setting up systems after installation for 

best performance”

5. Bass Remote Module:

Plug in the Bass Remote Module to the amplifi er “REMOTE” jack.

NOTE:

Minimum fi nal loudspeaker impedances:

4 & 2 Ohms stereo mode or 4-Ohms mono mode

This amplifi er will not do 1 Ohm stereo or 2/1 Ohm mono 

operation.

MBQR-1

Full range mono

This application illustrates the basic mono bridging method for all 

MB QUART amplifi ers.

Interconnect cable checklist:

A MONO signal source is required, such as would be available from 

the mono sub bass output of an active crossover, whether stand alo-

ne, or built into a head unit or equalizer. Important: Do not be temp-

ted to connect the hot, or positive outputs, from any source together 

to obtain a mono signal, as this could very well damage the output 

stage of that source.

It is necessary to feed the SAME signal to both left and right inputs 

via a Y-adapter RCA cable. Connect the mono speaker positive termi-

nal to the LEFT +, and its negative terminal to RIGHT -.

Switch setting checklist:

The AMPLIFIER X-OVER switch must be in the FULL position.

Crossover frequency control setting checklist:

N/A for full range operation.

TIP:

 If you are using the mono sub bass output of an active crossover, 

there is nothing wrong with switching in the low pass fi lter in these 

amplifi ers for a steeper low pass rolloff.

Minimum fi nal loudspeaker impedance:

4 ohm mono
