Both
ION4.4
and

have
simple
front

adjustable
phantom
power
and

the
mic/line
inputs.
The

is
primarily
intended
for
Serial

in
Cirrus
firmware

and
earlier
(Contact
Cirrus
logic
for
more
information).
There
are
2
network
ports
on
the
rear
panel
and
these
function
as
follows
(Note:
the
second
network
port
is
an
Ethernet
control
port
and
NOT
a
redundant
CobraNet™
port)…
•
CobraNet™
Port:
The
CobraNet™
port
uses
the
Cirrus
Logic
CS181xxx/CS496xxx
chipset
(similar
to
the
commonly
used
CM2
card).
This
allows
for
up
to
16
audio
input
channels
from
the
network,
up
to
16
audio
output
channels
to
the
network,
8
local
analog
mic/line
input
channels
and
8
local
analog
line
level
output
channels
from
the
network.
In
addition
to
audio
transport,
the
CobraNet™
port
provides
control
and
monitoring
capability
via
SNMP.
MTS
provides
an
OEM
version
of
Stardraw
control
with
embedded
MTS
SNMP
drivers
for
custom
GUI
rendering.
