4.1 Before starting
4.1.1 Packaging
In the interest of preserving the environment, Eaton
aims to use recycled packaging wherever practical.
Due to the physical nature of our products, we provide
adequate packaging to protect the goods during transit.
Please ensure that once unpacked, checked and
installed that all packaging is disposed of or recycled in a
responsible manner.
4.1.2 Electrostatic discharge
The Sonix PA/GA system is largely constructed from
electronic printed circuit boards. These printed circuit
boards are sensitive to static electricity; ESD discharge
on to any of the Eaton products could cause permanent
and irreparable damage to the equipment. All such
PCB’s are shipped to you in ESD protective bags for
transit. Prior to opening the transit bags please ensure
that you are wearing either an ESD, earthed wrist strap
or other suitable means of protection.
4.1.3 Safe working practice
Whilst working on or within the Sonix PA/GA system it
is our prime interest that you remain safe throughout.
During this work you may be exposed to potentially
hazardous voltages, currents, confined spaces and
potentially hazardous industrial environments. Prior to
undertaking any work please ensure relevant permits
and regulations are adhered to.

5 System connections
The 2Mx matrix connects to all its bus communication
channels via duplicated CAT6A cables. These connect
to the colour coordinated outputs on the rear of the
2Mx and in to RJ45 connectors on the corresponding
products.
Each CAT6A cables provides an audio & data control
feed and returns for the 2Mx. Each port has two RJ45
connectors which when connected, generate self-
healing loop. This ensure that in the unlikely event of a
cable failure the data will be fed in both directions and
maintain coverage to the units.
The top RJ45 of each 2Mx port connects to the top
entry on each corresponding unit’s port. For a single
loop, the return link connects to the bottom RJ45.
Where items are connected in series the bottom
connector of the fi rst unit connects to the top on the
next until it returns to the 2Mx.
ote:
N
It is recommended that within the PA/GA cabinet these cables
do not exceed 25 m in length.
5.1 DC Power
The 2Mx is powered via a 2-core 48 V dc input on the
rear of the unit. This input should be connected to the
managed 48 V dc power output from the Sonix PM10
power management unit.
As these cables are power feeds they should be routed
within the PA/GA system in a way as to avoid contact
with other signal, audio or high voltage cables.
