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
