How
to
Configure
Passthru
Audio
Adtec
EN-Series
encoders
have
the
flexibility
to
meet
many
demanding
audio
requirements.
Each
model
contains
specific
encoding
options,
but
every
Adtec
EN-Series
encoder
supports
two
audio
passthrus.
An
audio
passthru
consists
of
a
compressed
bitstream
(
Dolby
E
20
Bit
/
Dolby
E
16
Bit
/
Dolby
Digital
/
Linear
Acoustic
Stream
Stacker
2
)
or
an
uncompressed
stereo
pair
(
LPCM
)
from
an
embedded
SDI
or
AES
input
passed
into
the
egress
transport
stream
(
IP,
RF,
ASI
).
The
EN-210
supports
four
passthru
audios
on
the
first
four
audio
inputs.
The
SDI
Matrix
and
ASI
Transport
Stream
PID
configurations
allow
for
custom
configurations
if
required.
Every
audio
input
engine
has
an
internal
SDI
Matrix
to
route
any
audio
to
one
or
multiple
inputs.
Each
audio
engine
output
can
be
assigned
a
user
configurable
PID
in
the
transport
stream
to
meet
any
job
requirement.
If
the
passthru
audio
is
coming
in
via
embedded
SDI,
the
SDI
Audio
Matrix
may
be
used
in
conjunction
with
the
‘PID’
tab
to
manipulate
the
input
and
output
routing.
