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:
Minimum final loudspeaker impedances: - 1/2CH X-OVER: FULL
- 2 ohm per channel.
MODE: STEREO
Bridged for Subwoofer Application:
- Connect the mono speaker positive terminal to the LEFT +, and its negative terminal to RIGHT Here we show how to use the 2 channel amplifiers to power a subwoofer by taking
- as shown. advantage of the mono bridging capability of all MB Quart amplifiers.
Interconnect cable checklist:
Switch setting checklist: - A MONO signal source is required to bridge channels 1/2, such as would be available
- X-OVER: LPF from the mono sub bass output of an active crossover, whether standalone, or built into
Control checklist: 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 MODE to MONO. The
Minimum final loudspeaker impedances: amplifier will auto sum the signal and provide mono output.
- 2 ohm per channel in stereo mode. Important: Do not be tempted to connect the hot, or positive outputs, from any source
- 4 ohm mono bridged. together to obtain a mono signal, as this could very well damage the output stage of
that source.
