Sonifex AES67
Talkback Intercoms
The new range of Sonifex AVN talkback/listening/paging
intercoms aid communication...

S

onifex's
AVN
(Audio/Video/
Network) range use RAVENNA/
AES67 as the communication method
for the distribution of audio across a
network providing compatibility with
other AES67 systems and allowing
simple CAT-5 cabling and expansion.
The AVN-TB products are IP audio
based talkback intercom units with an
advanced feature set, allowing them
to be used in multiple applications.
With both 4-wire analogue inputs
and outputs, as well as AoIP network

Sonifex AVN-TB10AR

Sonifex AVN-TB6

audio connectivity, the AVN-TB units
can be used with existing legacy
4-wire systems and with new AES67
AoIP networked audio infrastructure.
Additionally, all audio is at 48kHz
sample rate, meaning that it's
broadcast quality audio as standard.
With dual 1Gb LAN ports and a 1Gb SFP
fibre port the products can be used in
larger networks.
The first intercom to be released was
the AVN-TB10AR, a 10 button intercom
meaning that 10 other 'stations'

can be defined, one per button, for
communication. At the IBC show, a
6-button version, the AVN-TB6, will be
on show. Comms can be made as a Talk
action, a Listen action or a duplex Talk/
Listen action to/from each station.
Coloured LEDs in the buttons help to
show which action is being used and
there is also a callback button for when
you're unavailable to receive a call.
The stations can be placed anywhere
on the AoIP network and the use of
Bonjour Device Discovery means that

other stations can be found quickly
and easily. The AVN-TB10AR can also
act as a PTP masterclock or slave clock
and supports IEEE1588-2008 PTPv2
media and default profiles.
Each unit has a built-in webserver
which is where the majority of settings
and configurations are made. The
front panel OLED display can also be
used to configure the unit, although
more functionality is available by
using the webserver. The webserver
is a responsive design meaning that
it can be used with small screens on
smartphones and tablets.
The unit has a front panel power
button and dual power connectors
- an IEC mains input and a 12V DC
input, which allows the AVN-TB10AR
to be used for both studio and mobile
installations. Also, a secondary power
source reduces the effect of power
down events. In any case, the unit
monitors the status of both power
sources and displays this on the front
panel.
Ten GPIOs (general purpose inputs/
outputs) and a programmable relay
output can be configured to indicate
critical states for the unit, via the 15way D-type connector, for example, to
show loss of DC power, or to show a
button press action.
