2 Channel Full Range Stereo:
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:
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.
Mono Operation:
- 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.

Interconnect cable checklist:
- 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

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.
