4 Installation and connectivity
4.1 Physical installation
The Sonix Io is a DIN rail mount unit, intended to be
mounted inside the PA/GA cabinet on most standard EN
60715 rails:
•
EN 50022 (Top hat, TS35, TS35D, type “O” or type
“Ω”) 35 x 7.5/15 mm rail,
•
EN 50045 (mini Top hat or TS15) 15 x 5.5 mm rail,
•
EN 50035 (type G or TS32) 32 x 15 mm.
Unit is simply clipped onto the appropriate rail, always
check that all sets of fixings have engaged correctly on
the rail.

Care must be taken to ensure that the product is correctly sup-
ported within the cabinet. Always check that both sets of fixings have
fully engaged on the rail and the unit is secured on both ends, with no
possibility of it to slide along the din rail.
4.2 DC Power
The Sonix Io is powered externally by 48 V dc. Eaton
recommends the supply voltage to be taken from
dedicated dc power output connection of the Sonix
Pm10 (see Pm10 Product Manual for connection details).
Green LED (D1) visible next to the power supply input
terminals illuminates to indicate that unit is powered up.

As these cables are power feeds, they should be – where pos-
sible – routed within the PA/GA system in a separate way to avoid
contact with signal or audio cables and reduce the possibility of inter-
ference.
Warning:
Observe the polarity of incoming
power supply cables.

4.3 Earth connection
The Sonix Io unit has an M4 stud for connection to
Earth. The Earth connection is used as a functional
reference for the unit screening only.
It is strongly recommended that any connection be
made to Telecoms Earth only.

4.4 Io Bus connections
The Sonix Io connects to the Sonix PA/GA system via
the Io bus communication channel utilising duplicated
CAT6A cables. This connection carries bi-directional
audio and serial data using RS-485 standard. The Sonix
PA/GA convention is that the Io bus uses BLUE coloured
CAT6A cables which connect to the colour coordinated
Io Bus sockets on the rear of the 2Mx unit.

Table 2 - IO Bus description
How the unit is connected in the system depends on the
number of units on the Io Bus.
The 2Mx Io bus connections are always top-top and
bottom-bottom, i.e. top port of the Sonix Io connects to
the top port of the Io Bus on the 2Mx. Whereas any inter
unit Io bus connections are always top-bottom.
For single unit the return link (bottom port of Io)
connects to the bottom port of the Io Bus on the 2Mx,
as shown below.
