Quick Start

This Is The Part Of The Manual To Read If You Don’t Read Anything Else.

• Install the 9 volt battery into the MP-200.

• Plug the included CM-10 microphone into INPUT 1 on the MP-200. Important Note: The MP-

200 is only designed to be used with the AudioControl Industrial CM-10 microphone. Other
mics will not properly register on the 94dB reference and may not operate on the 12 volt
phantom power output.

• Connect the LINE OUTPUT of the MP-200 to your analyzer or computer sound input.

• Set the MIC GAIN knob on the MP-200 to 0 dB. At this setting, the output signal level will be

24.5 mV

RMS

 at 94 dB sound pressure level (1 Pascal).

• If you need a test signal, connect the PINK NOISE OUTPUT of the MP-200 to a line level

input on your system under test. Note: To prolong battery life, the pink noise circuitry of the
MP-200 only receives power when a ¼" plug is inserted into the PINK NOISE OUTPUT jack.
Disconnect the plug from the pink noise output jack when not in use.
