AES67 - A positive for
AoIP Talkback Systems
Innovation and development in technology can take several
forms, Sonifex is highlighting a new standard...

S

ometimes it's the organisation and
structured use of the technology
that makes the difference - a new
standard has come along in the last
five years that is making the world of
intercom a whole lot more productive
- AoIP (Audio over IP) which has been
around for a few decades, but more
specifically AES67 AoIP.
What's AES67? Well it's been in the
broadcast press a lot recently and
it's best summed up by Wikipedia:
"AES67 is an open standard for audio
over IP and audio over Ethernet
interoperability. The standard was
developed by the Audio Engineering
Society and published in September

2013. It is a layer 3 protocol suite
based on existing standards and is
designed to allow interoperability
between various IP-based audio
networking systems such as RAVENNA,
Livewire, Q-LAN and Dante."
So there you have it. The important
word in that description though
is 'interoperability'. There have
been many proprietary and open
systems in existence for years, but an
interoperable standard is what has
been missing.
Sonifex is using the open RAVENNA
standard for AoIP on its AVN range
of AoIP products and by default
RAVENNA is AES67 compatible - it's

one of the reasons that Sonifex
initially decided to use RAVENNA,
because of its open nature and also
because of the AES67 compatibility.
RAVENNA and AES67 have allowed
Sonifex as a manufacturer to
develop products using licence-free
AoIP systems which are, or will be,
compatible with the majority of AoIP
audio products on the market and
which can provide multi-channel
(hundreds of channels) audio with
synchronised millisecond accuracy.
AES67 marks the beginning of a
concerted effort by manufacturers
to make sure that their equipment
works with other AES67 equipment.

And whilst AES67 isn't the whole
story (since there are some differing
discovery mechanisms for devices on
a network, and different mechanisms
for the transfer of ancillary data, such
as GPIOs for example) it's a very big
step in the right direction.
See
Sonifex's
latest
AES67
compatible products at the show - the
AVN-TB10AR is a 10-button intercom
to aid communication between
studios, stages, theatres, offices and
different areas in a facility or building
complex.
Ten other 'stations' can be defined,
one per button, for communication
with other talkback units on the
network. Each unit has both 4-wire
and AoIP connectivity, with all audio
transferred over a network, enabling
it to be used in existing legacy
systems, or in completely new AES67
AoIP networked audio infrastructure.
With dual 1Gb LAN ports and a 1Gb
SFP fibre port the products can be
used in larger networks too.
