The BOWS supports streaming audio over IP Networks using the BARIX
Audio-over-IP modules. There are many possible configurations that can
be used, depending on the application. Please refer to the BOWS IP
Networking Manual (LT0561) and the BARIX website (
for further details.
One typical application is to use the BARIX modules to allow a master
BOWS to make emergency PA announcements to 1 or more slave
BOWS connected together on a LAN.
For this application an Annuncicom 200 is used in the master BOWS and
either an Annuncicom 200 or Exstreamer 100 at each slave BOWS as
shown in Figure 25.

At the master BOWS the Annuncicom 200 is connected to the BOWS
Interface board as per Figure 26. The J15

signals from the BOWS Interface board are connected to both the T-GEN
master J1 MIC input connector and to the Line Level and Input 0 inputs
on the Annuncicom 200.
