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

PAD REMOTE CONTROLS XLR/ RCA REAR PANEL CONNECTIONS AND SWITCHES Source Inputs The Source Inputs 1,2,3 and 4 are stereo RCA unbalanced jacks, which feed signal to the front panel routing switches. Maximum signal level is +24dB. The Left and Right signals are summed together and the mono signal is distributed to the Zone Outputs. Remote Controls The Remote Control Connections allow optional MPM4R remote control accessory plates to be used for source selection and volume control.

Zone Max Level. An appropriate maximum volume for the listening environment can be established by setting the audio level going to each Zone Output. This feature allows the installer to determine the maximum level of all audio inputs into each zone by coordinating the output gain of the MPM4 to the inputs of the Zone power amps. This is an analog final output gain stage with 20dB of gain and 60dB of attenuation, adjustable in 1dB steps. Each encoder detent equals 1dB.

TYPICAL SETUP PROCEDURE Installation Tip To facilitate the most expedient setup experience, it may be desirable to do the initial setup with the MPM4 unit physically in each Zone. If a paging mic is to be used in the zone, that wire can be used with adapters to send the output of the MPM4 back to the power amps in the system equipment location. Pulling a shielded audio pair along with the CAT 5 wire for the remotes would also make this possible.

DSP Input Equalization By the application of digital filters for equalization, the MPM4 achieves perfect matching and repeatability of equalization that cannot be achieved with analog filters. The equalization curves are modeled after analog equalizers to give the smooth response expected from analog equalizers.
