MX202 Plate Mount Preamp Wiring SchemeFAQ #3422
Question:How are the wires connected in to and out of the MX202 plate-mount preamp?
The input is a terminal strip with 3 connection points; the output is the same type of terminal strip.
The preamp input is labelled: R B S
R = red wire (carries +5 Vdc bias to the mic)
B = black wire (carries the audio signal from the mic)
S = cable shield (return path for bias and audio)
The preamp output is labelled: S + -
+ = audio send
- = audio return
S = cable shield
The preamp output is a balanced, mic level signal.
NOTE: The MX202 preamp requires phantom power to operate.
