Control checklist:

Interconnect cable checklist:

- Refer to the section “Settings for Best Performance”

- Connect the two inputs of the amplifier to a Radio/CD with quality RCA cables.
Switch setting checklist:

Minimum final loudspeaker impedances:

- 1/2CH X-OVER:  FULL

- You can also feed the SAME signal to both left and right inputs via a Y-adapter RCA cable.

- Connect the mono speaker positive terminal to the RIGHT +, and its negative terminal to LEFT 
- as shown.

Here we show how to use the 2 channel amplifiers as a 1 channel unit by taking 
advantage of the mono bridging capability of all MB Quart amplifiers.

- X-OVER: LP/BP

- A MONO signal source is required to bridge channels 1/2, such as would be available 
from the mono sub bass output of an active crossover, whether standalone, or built into 

a head unit or equalizer. If you only have 1 set of RCA outputs from your headunit, you 

- Refer to the section “Settings for Best Performance”

can simply connect those to the inputs for ch 1/2 and switch the X-OVER to LP/BP. The 

amplifier will auto sum the signal and provide mono output for bridged channels 1/2. 

Important: Do not be tempted 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.
