5 Installation and connectivity
The Ms12 is designed to be mounted within industry
standard 19” frames, taking up a 1U equivalent space.
The unit is attached to the 19” frame within the cabinet
by the four mounting holes on the front panel. Care
should be taken to ensure no ventilation points are
obstructed and that the product is correctly supported
within the cabinet.
The Ms12 unit can be connected to the system in two
different ways:
•
Directly on the Sonix PA/GA system’s IO-Bus via
CAT6A cabling
•
Into the Sonix PA/GA systems’ Io module via audio
and key line using two twisted pair cables
ote:
N
It is not recommended that both CAT6A and audio + key-line
connections are used into the same PA/GA system simultaneously.
Prior to connecting any field cables to the Ms12 they
must be checked and recorded for the following
•
All power and signal conductors free from Earth.
•
Correct voltages are provided on power and signal
cables
All faults must be rectified prior to connecting to the
unit, with attention to cable polarity.
5 .1 RJ45 IO Bus ports
When the Ms12 is installed as an integral component
within the PA/GA cabinet, it connects to the Sonix 2Mx
Central Controller via the IO bus. These are identified
by the blue CAT6A cables which connect the rear of the
2Mx with the Ms12 using the RJ45 connectors. The
IO bus is usually connected as loop from the 2mx to
provide redundant paths for the control data, status data
and audio should they be needed.
A second set of RJ45 connectors provides a full
duplicate audio and data path to a second 2Mx (usually
the B-side system) for redundancy.

5 .2 Isolated audio and key-line outputs
Two 5-way connectors provide a duplicated interface
for connection to other third-party equipment to operate
along-side the RJ45 connections. Each connection
carries isolated audio and control lines. These interfaces
can also be used as an alternative to the CAT6A
connections provided they are connected a Sonix Io
unit’s audio and key-line input. Message playback
causes the key line to activate, and the message audio,
preceded by chime, is replayed to terminals.
