Sonix 350-d Technical Manual
The 350-d will generate 100V line audio regardless of
the zone being requested, while the Zone Controller unit
(for a Sonix PA/GA system, typically a dedicated Sonix Io
unit) will connect the correct zone for broadcast via the
Relay Bank.
Post amplifi er switching has been carefully designed
to support loop monitoring, assuming the individual
loudspeaker connections to the Relay Bank are complete
loops. During system idle, the audio routing relays are
confi gured to create one big loop out of all connected
speaker loops, this allows the standard sense test to
monitor the complete loop (see section 5.3.2). During
an active system broadcast, the audio routing relays are
re-confi gured so that only required zone speaker loops
are driven and any active loops are in parallel. This means
that there is no need to increase the loudspeaker 100V
line cable weight to adjust for the speaker load in other
zones. Care needs to be taken while wiring to ensure
that loop monitoring is not lost.
Warning: The cumulative load of all the speakers
connected to the Relay Bank cannot exceed 350
W (maximum load for a single 350-d unit).

Post-amp Switching is considered an ETO (Engineer to Order).
Please consult your local Eaton representative for exact configuration
requirements to support this.
5.4.3 Routine Speech disabled
If 350-d is intended for a zone where Routine Speech is
not desired (i.e. accommodation), it is possible to disable
Routine Speech in the confi guration. The amplifi er will
then only respond to Important Message and Alarm
broadcast requests. See SAS Product Manual for details.
5.5 Hot Standby amplifi ers
When a Sonix 350-d reports a fault condition and is
unable to generate audio, a unit set as Hot Standby
amplifi er will take over the broadcast to ensure no loss
in coverage. In
Figure 21
and
Figure 22
below, the
green arrow represents the 100 V Line audio path, as it
covers the broadcast for a faulty amplifi er:
