Setup Procedure

Locate the MMP-10 approximately 2/3 back from the screen, off
axis of the center speaker, usually between the center speaker
and the right speaker to allow for viewing from the booth. Place
microphone one at this position. Place the remaining mics. in a
diamond pattern within the central area of the room. The micro-
phones should be positioned horizontally with the microphone's
screen facing up, toward the ceiling (Figure2). Insert the micro-
phone connectors into the appropriate jacks on the MMP-10.
Connect the audio cable to the MMP-10 and switch the unit on.
The red LED for microphone one will be on. Be sure to position
the MMP-10 so you can view the LED display from the booth.
Plug the other end (i.e. momentary switch side) of the audio
cable into your analyzer up in the projection booth. Switch on
Pink Noise. Your MMP-10 wakes up with microphone one
selected. Verify you have a signal from microphone one on your
analyzer. Select microphone two, three then four to verify
operation.
Select multiplex mode (indicated by the LEDs flashing in order:
red, green, green green) and set your analyzer to the proper level
and commence room equalization.
The multiplexer has been designed to allow for easy room
averaging with a small but accurate four microphone multi-
plexer system. Room equalization using only one microphone is
not recommended due to room modes. Using four microphones
and MMP-10 multiplexer will allow for the best sound for the
greatest number of seats in the room.
Remote control of the MMP-10 is achieved by using a momen-
tary in-line push button located on the audio cable plugged into
your analyzer. Pressing the button located on this cable cycles
the MMP-10 through five states: Microphone 1, microphone 2,
microphone 3, microphone 4 and multiplex (scan) mode.
