depends on mode selected.
Level Controls the volume level in dBs
Analog Control the volume level -15 to
Audio Level +15 (dBs) in 1 dB increments for
AUDIO 1 and 2 only
Sync Audio Sync sets the audio sync
offset. This measurement is in
milliseconds, and works only on
analog audios.
Musicam Allows the operator to choose how
Mode to encode left and right analog
audio inputs.
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.
SDI Pair Allows the operator to route
embedded audio from SDI input to
the specified audio encoder.
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.
