INTRODUCTION

Thank you for selecting the MPM4 music and paging manager.  This high quality, versatile device can be 
used in countless applications to provide comprehensive control of multiple audio sources and distribute 
them to four separate locations. Features include four stereo inputs for audio connection of CD and MP3 
players, radio tuners, TV receivers and DVD players, etc.; four priority inputs which allow paging and 
automatic music override for announcements or a jukebox, and four mono output zones with balanced 
and unbalanced connections.  A four-band equalizer is provided on each input and output for enhancing 
the overall sound of the system.  The simple and intuitive front panel displays the source routing to each 
zone with metering to indicate signal levels and presence.  Front panel pushbuttons and volume controls, 
or a remote control in each zone, make source selection and level adjustments easy and convenient.   
Occupying two rack spaces and designed for continuous operation, the MPM4 includes all the features 
necessary to operate most multi-zone sound system installations in night clubs, sports bars, health clubs, 
offices, restaurants or anywhere paging and/or priority inputs are required.

FEATURES

Simple, convenient controls are easy to use
Four mono output zones, independently controlled
Four source inputs assignable from the front panel
Four priority inputs for paging and audio insertion to each zone
Separate 4-band EQ on each source input, priority input and zone output
Input trim gain stages for matching input levels 
Optional remote control of source selection and volume in each zone
Password protected installation settings
No computer required for setup or operation
