ML-116 INSTALLATION DATA
SYSTEM CONFIGURATION
The ML-116 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 rack mounted Audio Control
Unit (ACU) unit can handle up to 16 rooms and was designed to be linked together with other ACU’s
to control the audio in up to 128 rooms.
The basic system configuration consists of an ACU, Map Panel, Monitor Panel, Wallplates and an
optional Facility Manager’s Panel. Each unit of the ML-116 has its own unique responsibility and
processing is distributed throughout the entire system. The responsibilities of each unit is described
below:
ACU UNIT
The ACU is the rack mounted brain of the system. It contains the CPU module, one RA2 (room audio)
module per 2 rooms, a Regulator module, a MP (music page input) module, and an HTP (head table
and page control) module.
The CPU module is the central controller of the system. It is responsible for controlling the other
modules and receives data on what to do from the Wallplates, Monitor Panel, and Map Panel and/or
FM 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 PANEL & REMOTE MAP PANEL
The Map Panel is responsible for controlling the system setup by mixing rooms together and selecting
head table locations. It is microcontroller based and communicates to the CPU module. The map panel
is fabricated at the factory and is not configurable on site.
MONITOR PANEL & REMOTE MONITOR PANEL
The monitor panel is also a microprocessor controlled module placed near the ACU unit which allows
the user to ‘monitor’ the settings in a room. The user can adjust those settings by using the monitor
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 imitating the Map Panel and
has the ability to combine rooms without mix switches. It is customized 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 was implemented.
