INTRODUCTION

Designed for hotels and conference centers with divisible, multi-use meeting rooms, the ML-116 Ball-

roomCombiningSystemunifiestheaudiosystemofeachroombeingjoinedtogetherwithasimpletouch

of a button.

The ML-116 is the latest, enhanced version of the popular ML-112A .A microprocessor-based system,

the ML-116 is capable of combining up to sixteen rooms in multiple configurations.Contractors appreci-

ate the flexibility of the ML-116 which can be operated with a variety of mixers, equalizers and power

amps.

Hotel and meeting-center operators give high marks to the system's dependability and operation. Staff

require little training to competently use the equipment.

Flexible and dependable sound systems are increasingly important for conference planners looking for

waysto make their events stand out. The ML-116fulfills the hotel and meeting-centers needs and clients'

wishes and have been designed so, if desired, even the guests can play an active part in its operation.

FEATURES

• Provides for 4 background music sources.

• Capable of combining up to 16 rooms of audio with the touch of a button.

• Can combine up to 4 ML-116's to control 64 rooms with full functionality.

• Optional Facility Manager panel permits operation of the system from a standard computer in any

locationwithinthefacility.

• Facility Manager Panel allows the mixing of non-adjacent rooms.

•Can interface with lighting systems.

•Continuouslyadjustable ramping bargraph volumecontrol on each wallplateforboth microphone

and background music.

• Membrane type wallplates enhance room's decor.

• Operates with any mixer.

•Complete paging capability.

• Total reliability; the ML-116 builds on the 7 year reputation of its predecessor, the ML-112A, in its

engineering design, proven components, quality workmanship, and responsible operation.

ACU Description

The Audio Control Unit is the main unit of the system. It

routes the selected music, adjusts levels, combines rooms,

handlescommunication(betweenwallplates,map,andmoni-

tor panels), and can route audio to other ML-116s. It also

controls the paging function.

Refer to Figure 1 for the following discussion.

The ACU RA2 module provides the audio interface for two

rooms.AllRA2modulesarefullyinterchangeable.The mod-

ule identifies the two rooms by an ODD and EVEN nomen-

clature. The numbers that appear on the top of the ACU

module slot refer to the room's number in the system. These

numbers also correspond to the numbers in each room drawn

on the map panel.
