ML-800 SYSTEM CONFIGURATION
The ML-800 system allows the user greater flexibility than any other room combining system made
today! No other system allows the user the choice of 4 music input selections, or provides the local
mixer enable that greatly reduces distortion when combining rooms.
The basic system configuration consists of the ML-800 RACK which contains the Map / Monitor Panel,
Wallplates, either membrane or touch, and an optional Facility Manager’s Panel. Each unit of the ML-
800 has its own unique responsibility and processing is distributed throughout the entire system. The
responsibilities of each unit is described below:
ML-800 RACK
The ML-800RACK is the main controller of the system. It contains the CPU module, local audio,
power supply regulation, a MP (music page input) module.
The internal CPU module is responsible for controlling the other modules and receives data on what to
do from the Wallplates, Monitor / Map Panel and/or FM (Facility Manager) Panel. It uses dip switches
(discussed in the Dip switch/Jumper section) to determine settings and operating modes.
WALLPLATES
The wallplates are microprocessor controlled modules that are used for room audio control. They are
responsible for setting Local Input on/off, Music on/off, Music Selection, Local Input Volume, Music
Volume, and Local Mixer Enable on/off. The Section on Dip Switches describes the settings used on
the wallplates and those on the CPU module that set modes on the wallplates.
MAP / MONITOR PANEL & REMOTE MAP PANEL
The Map Panel is responsible for controlling the system setup by mixing rooms together. It is
microcontroller based and communicates to the CPU module in the ML-800RACK.
The monitor section, is also microprocessor controlled which allows the user to ‘monitor’ the settings in
a room. The user can adjust those settings by using the Map panel’s built in ‘wallplate’.
FACILITY MANAGER’S SOFTWARE PANEL, including the FM-INT Unit
This is a software program that runs on a PC and controls the system by replicating ML-800RACK
functions and status indicators and has the ability to combine rooms without mix switches. It is custom-
ized and is not configurable. It communicates over two twisted pairs to the ACU using a multidrop
proprietary protocol. The FM-INT Unit interfaces this line to the computer. An enclosed audio speaker
would also be used if the audio feed option was implemented.
