2 Channel Full Range Stereo:
Interconnect cable checklist:
- Connect the inputs of the amplifier to a Radio/CD with
quality RCA cables.
Switch setting checklist:
- 1/2CH X-OVER: FULL
MODE: “STEREO” since channels are being run
independently.
Control checklist:
- Refer to the section “Settings for Best Performance”
Minimum final loudspeaker impedances:
- 2 ohm per channel.
MONO:
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:
- Connect the inputs of channel pair 1/2 to a suitable signal
source, e.g. a head unit with good quality RCA cables.
- A MONO signal source is suggested, 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.
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.
- It is suggested to feed the SAME signal to both left and
right inputs via a Y-adapter RCA cable.
- Connect the mono speaker positive terminal to the LEFT
+, and its negative terminal to RIGHT - as shown.
