Adjusting the MLP 101 D
Most adjustment options for the MLP 101 D are located on its
rear panel (see “Rear Panel Features” in this chapter for details).
Therefore, you must perform these adjustments prior to final
mounting into a wall.
To adjust the MLP 101 D, do the following:
1.
If using a condenser microphone, flip the Phantom power
switch to the “on” position.
If using a dynamic microphone, flip the Phantom power
switch to the “off” position.
2. When using the microphone for voice audio, flip the Low
Cut switch to “on” to reduce wind and “table rumble”
noise.
When using the microphone for music audio, flip the Low
Cut switch to “off” to preserve the optimum sound quality.
3. Set the Mic Gain pot by saying a few words into the
microphone and adjusting for the maximum sound level
that is free of distortion.
N
If there is a remote control connection, unplug it while
adjusting the Mic Gain pot. Replace the remote control
when finished.
If there is minimal distortion, but greater volume is
required, turn the Mic Gain pot clockwise (towards the
75 dB mark) to increase the volume, but not past the point
where distortion occurs.
