4 About the product
4.1 Product description
The Sonix PA/GA system autonomously monitors and
supervises the amplier, loudspeaker cable insulation
and loop integrity with a 22 kHz inaudible out of band
signal at a regular interval up to every 30 seconds.
The robust and industrial design of the system ensures
its protection against open, short circuit, load deviation
and abnormal loads associated with eld loop faults. In
the event of such common eld loop faults, the Sonix
PA/GA rapidly detects, reports and diagnoses the fault,
reporting this information back via the amplier, 2Mx
controller and onward to ICCS output and to the Sonix
software. During this, the amplier intelligently protects
the output from permanent damage.
Provided with blade terminals on amplier loop outputs
to securely and safely isolate the eld cables for testing
and fault rectication. The Eol8 ensures that, at all times,
eld speakers are driven with audio signals in both
directions. This self-healing loop design feature ensures
that in the event of an open circuit condition critical
communications are not lost.
Within the Sonix central cabinet the Eol8 is connected
via rapid t RJ45 connectors, ensuring a quick and
failsafe connection to the amplier. In the event that any
internal RJ45 cable are disconnected the faults will be
logged on the Sonix system.
Each Eol8 can support up to 8 ampliers.
4.2 Key features
• Supports up to 8 amplifiers
• Out of band discrete monitoring signals
• Dual RJ45 connectivity for easy maintenance
• Field cable lightning protection

5 Installation
5.1 Before starting
5.1.1 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 / recycled in a responsible
manner.
5.1.2 Electrostatic discharge
The Sonix PA/GA system is largely constructed from

complete the wiring.
ote:N Ensure the system is not powered when Sonix Eol8 protective
cover is NOT fitted.
5.4 Electrical Connections
Sonix Eol8 is equipped with 8off pairs of RJ45 CAT6A
plugs for connection of up to 8 ampliers and 32 Phoenix
Contact blade connectors for on eld loudspeaker loop
termination.
Warning: The CAT6A cables carry 100V audio power
line, Electrical Shock risk warning labels shall be tted
on both ends.
5.4.1 EOL Bus connections (RJ45 CAT6A)
The RJ45 EOL Bus connections should be made top
and bottom from Sonix 350-d amplier to the Eol8. The
audio from the amplier will output on the corresponding
4 ports.
There is no polarity on the EOL bus connections, they
can be connected Top-Top, Top-Bottom or Bottom-
Bottom.
Warning: Do NOT cross-connect EOL connections
between ampliers, always connect in top & bottom
pairs.
The EOL Bus cables also carry a safety interlock
signal to prevent the amplier from outputting 100 V
audio when both EOL connections are not correctly
terminated.

6 Loudspeaker wiring
The Sonix Eol8 can be used to support different modes
of operation of loudspeaker connections, as detailed
here. Different modes can be mixed and matched on
each of the Eol8 outputs, but a single amplier can only
support one mode at a time.
6.1 Single loudspeaker loop wiring
This wiring conguration is used allow an amplier to
drive a single loudspeaker loop.
6.2 Multiple loudspeaker loops per amplier
Loudspeaker loops can be concatenated together to
form a bigger loop for a single amplier to drive.
Warning: All loudspeaker loops that are merged
together need to have cable weights that support
the total amplier load.
Figure 3 - Multiple loop wiring
6.3 Spur wiring
The Sonix system can support monitored spur but it is
not as fault tolerant as loop-based wiring topologies.
Figure 4 - Spur wiring with Eol1 tted.
ote:N This mode does NOT support ‘loop monitoring’ without an Eol-1
fitted at the end of the spur but can operate without.
ote:N Requires correct configuration of amplifier to support Eol1 unit
6.4 Post-Amplier Switching
It is possible to utilise a relay set to control the audio
output of an amplier into multiple independent
loudspeaker loops. This can be done while also
maintaining loop monitoring.
ote:N This is considered ETO (Engineer to Order), please consult your
local Eaton representative for exact configuration requirements to sup-
port Post-Amplifier switching
6.5 Conguration/Setup
The conguration switches, SW1 – SW8, are
pre-set during production. Ensuring switches SW1-8 as
per Figure 1 - Eol8 Connection are set toward RJ45
connectors will avoid potential audio loop malfunction.
