depends on mode selected.
If MPEG 1 Layer 2, the available rates
are 32, 48, 56, 64, 80, 96, 112, 128,
160, 192*, 224, 256, 320, 384
kBits/sec .
If Dolby Digital AC3, the available
rates are 56, 64, 80, 96, 112, 128,
160, 192*, 224, 256, 320, 384, 448,
512, 576, 640 kBits/sec.
Note: * For MPEG 1 Layer 2 and Dolby
Digital AC3, the recommended lowest
rate for professional applications is
192 kBits/sec.
In Dolby-E mode, do not set this value.
The bitrate will be auto-detected.
Level Controls the volume level in dBs user-defined using the numeric
keypad
range = -18 dBs to 8 dBs in
increments of 1
Analog
Audio Level
Control the volume level -15 to
+15 (dBs) in 1 dB increments for
AUDIO 1 and 2 only
This trims the level on the analog
audio path (only) to accomodate
external audio gear variability.
Sync Audio Sync sets the audio sync
offset. This measurement is in
milliseconds, and works only on
analog audios.

Musicam
Mode Allows the operator to choose how
to encode left and right analog
audio inputs.
STEREO
MONO
DUALMONO
IFB This is a low latency audio path
for communications to a remote
van or studio using the same
distribution path. It requires a
special IFB receiver or manual PID
selection with a standard IRD.
Note: There is no PID reference in
the PMT for this functionality. It is
considered a ghost PID. It is also
not lip-sync aligned with video.

GHOST
SDI Pair Allows the operator to route
embedded audio from SDI input to
the specified audio encoder.
