ML-116 INSTALLATION DATA
A.........There will be two types of wallplates available for use in the ML-116 system; membrane
and LCD. Both control all wallplate functions. These functions include Music Selection,
Room Mixer Enable, Music Enable and Volume, and Local Input On/Off and Volume.
B.........Each room in the system can have two wallplates if desired.
C.........The ACU (audio control unit) is the main unit of the system. It routes the selected music,
adjusts levels, combines rooms, handles communications (between wallplates, map, and
monitor panels), and can talk to other ML-116s. It also controls the paging function.
D.........The HT-8 is a PC board assembly with 8 relays to control the speaker feeds to the head
table locations. These cards are driven by the HTBC board.
E........ The PSA is the Power Supply for the ML-116 system.
F........ The Monitor/VU Panel permits an operator to monitor the audio from any selected room.
It also permits the operation of any wallplate function from this same panel.
G........ The Monitor Relay Card is a PC board assembly of relays that mounts close to the power
amps and provides the audio feed for the monitor panel.
H.........This wall plug-in transformer powers the HTBC and HT-8 cards.
J........ The HTBC Board is essentially a breakout that accepts power and signal input and drives
the HT-8 cards.
These three remaining items are described and shown further on in this document.
K....... This is the R-MAP unit that repeats the data on the rack map panel (see page 40)
L....... This is the R-MON unit that repeats the data on the rack monitor panel (see page 40)
M...... This is the ML-116-INT unit to handle the lighting interface (see page 42)
