• The DIP switches
The 6-DIP switch located on the rear panel provides phantom power for each individual microphone input, selects mono or
stereo output operation, and activates the internal limiter. The limiter is used to compress the overall MX442 signal to a level
which will not 4 dB. Note that this limiter may be adjusted by the screwdriver potentiometer located between the
Channel 3 and Channel 4 Pan pots. If the MX442 is being used in an area where there is a wide dynamic range of sounds
(the sound varies from very quiet to very loud), the limiter is used to keep the signal within a certain manageable range. The
Mono/Stereo switch, when in the Mono (down) position, both the Right and Left outputs are summed together. Finally,
switches 3 through 6 provide the indicated channel with +48 volts of phantom power to power condenser type microphones.
