FS2 Frame Synchronizer/Converter v3.0 54 www.aja.com
Bypass is available for use when Dolby® 5.1 and similar schemes need to be
preserved and the audio data passed unaltered (no SRC is applied).
Set these parameters to Manual (14.0)and Bypass (14.1-14.8) only if BOTH the
following items are true:
• You want to pass unaltered digital encoded audio from either an embedded
or AES Input to an embedded and/or AES Output.
• You have the embedded or AES input genlocked to the FS2 output. In other
words, the encoded audio will not survive the frame-sync function (dropping
or repeating frames) so it needs to be set to lock to the input. You can lock
to a reference only if that reference is driving both the FS2 and the upstream
source of the embedded or AES input to the FS2.
On (default)
Bypass
Audio sample rate conversion (SRC) is applied to the affected
channel pairs and keeps the video and audio synchronized.
Audio sample rate conversion (SRC) is NOT applied to the affected
channel pairs. The signal is passed through unaltered, which
is useful for preserving Dolby® 5.1 embedded audio and other
applications where existing data on the input must be preserved
and passed to the output.

16 Dolby Decoder Mode
This parameter determines the Dolby Decoder “Bitstream Detect Mode” on the
Dolby Decoder Card. In Auto mode, the Dolby Decoder decodes Dolby E, Dolby
Digital, or Dolby DigitalPlus bitstreams. If none of the above are detected, the
card passes the incoming audio as PCM.
In Dolby E mode, the Dolby Decoder only decodes Dolby E bitstreams, and mutes
its outputs if it detects anything else.
In Dolby D mode, the Dolby Decoder only decodes Dolby Digital or Dolby
DigitalPlus bitstreams, and mutes its outputs if it detects anything else.
Auto (default)
Dolby E

Automatically decode Dolby E, Dolby digital, Dolby DigitalPlus,
or PCM.
Decode Dolby E only.
Decode Dolby Digital or Dolby DigitalPlus only.
