Livewire
TM
If
you
are
already
familiar
with
Axia’s
audio
nodes,
you
might
think
of
this
new
version
of
the
Zephyr
Xstream
as
an
“original”
Xstream
codec
with
a
2x2
node
on
the
front
of
it.
The
LAN
port
will
be
used
for
all
Livewire
audio
connections
in
and
out
of
the
codec.
As
with
all
Livewire
TM
devices,
the
Livewire
streams
being
delivered
to
the
network
require
unique
ID
numbers.
The
two
most
important
concepts
to
understand
are:
1.
The
Livewire
TM
destinations
deliver
audio
to
the
inputs
to
the
Xstream
codec.
2.
The
outputs
of
the
Xstream
codec
(Hybrid
Channels)
will
become
the
codec’s
Livewire
TM
sources
to
your
Axia
Livewire
network.
The
virtual
2x2
node,
in
combination
with
the
codec,
has
some
unique
mono/stereo
features:
•
If
the
stream
being
received
by
the
codec
is
stereo
‐
both
codec
outputs
(Livewire
sources)
will
be
stereo
with
both
delivering
identical
stereo
streams.
•
If
the
stream
being
received
by
the
codec
is
dual
mono
(such
as
G.722),
the
decoded
audio
is
split
between
the
two
Livewire
TM
sources.
The
first
source
has
the
A
mono
feed
replicated
on
both
left
and
right
channels.
The
second
source
has
the
B
mono
feed
on
both
channels.
Thus
‐
when
you
are
using
dual
mono,
you
will
use
both
codec
outputs
as
independent
Livewire
sources.
•
Remember,
Livewire
TM
streams
are
always
stereo.
In
the
case
of
a
mono
source
as
described
above,
the
mono
data
is
simply
replicated
on
both
left
and
right
channels.
•
Dual/Mono
TRANSMIT
works
only
in
Layer
3
Dual/Mono
mode.
In
Layer
3
Dual/Mono
transmit;
the
left
channel
of
the
first
destination
is
used
to
create
the
“Channel
A”
mono
feed
to
be
sent
over
ISDN.
The
second
destination
is
used
for
the
“Channel
B”
mono
transmit
feed.
The
right
channel
of
each
of
those
streams
is
ignored.
A
Word
about
Livewire
Codec
Backfeeds
Backfeeds
to
a
codec
in
the
Livewire
TM
world
are
always
stereo.
By
default,
the
right
channel
of
the
backfeed
is
a
L/R
mono
sum
of
the
configured
program
source
(usually
PGM1).
The
left
channel
is
the
same
PLUS
talkback.
The
left
channel
program
can
be
dimmed
or
muted
when
talkback
is
present.
