MP-200 Operation Manual

Important Note: The MP-200

is designed to be used with

the AudioControl Industrial

CM-10 microphone only. Use

with any other microphone

will produce unpredictable

results.

Basic information about the MP-200 and CM-10 most analyzer systems

need to know:

• Mic Sensitivity

24.5 mVrms @ 94 dB SPL (1 Pascal)

• Mic Gain (dB)

Basic System Setup

The basic application setup with the MP-200 system is very simple: Plug one or two CM-10 microphones

into the MP-200 preamp, connect the line level input if necessary, and feed the line output of the preamp

into your analyzer or measurement system. Once you have connected the system together, operation of the

MP-200 is straightforward: Set the MIKE GAIN control to the amount of signal increase you need from

the CM-10 mic to your analysis system.

To make a useful measurement of any system, you need to eliminate

as many unknown items as possible. For audio analysis, this means

that you need to know what signal is fed into a system and have a

microphone/preamp with a flat frequency response to listen to what is

coming out of the system. The two primary methods of getting a

known test signal are to: 1) Use a test signal such as pink noise that

has an equal amplitude at all frequencies (flat response), or 2) Use a

second input channel on the analyzer to monitor the signal fed into the

system and mathematically compare the output signal to the input.

Not all analyzer systems have this capability to compare two signals.
