c If PMT Order is selected, you must set the PMT order for each audio (None,
AUD1 to AUD64). You cannot select the same PID for both audio devices. If
you select the same instance of an audio PID for one of the audio devices, the
other audio device PID instance will automatically increment by one. For
example, Audio 1 is set to AUD1 and Audio 2 is set to AUD2. If you change
Audio 1 source to AUD2, the Audio 2 source will automatically change to
AUD3 to resolve the conflict.

b From the AC3 Compression drop-down list, choose the mode to use if the
output is compressed Dolby Digital audio. The selections are Line Mode,

4 The following options only appear for D9854-I or D9854 with SDI:
a Set the Digital Out Preference for the SDI output or AES-3id output. The
following describes the options:
Mode
Description
PCM Samples
If the audio source is MPEG Layer II format, the output will be
routed to the SDI output as PCM.
routed to the SDI output as PCM.
Compressed
If the audio source is AES compressed, the output will routed to the
AES-3id output, compressed.
AES-3id output, compressed.
When Digital Out Preference is set to PCM Samples, the output is PCM
regardless of whether it's MPEG, Dolby Digital (AC-3) or AAC audio.
Additionally, when the output is Compressed, MPEG-1 L1 and L2 will be
output PCM, even though Dolby Digital (AC-3) and AAC is compressed (and
transcoded).
