8.1–8.16 Audio Phase Ch1–16
These parameters select whether audio phase is normal (same as passed from the
input) or inverted on Channels 1–16. This may be useful to correct analog audio
signals that are incorrectly wired, placing audio out of phase at input.
Normal (default)
Invert
Phase is unaltered as it passes from the input to the output.
Phase is inverted as it passes from the input to output.
If parameter 3 Audio Follow Video is set to On, then Audio Output Phase selection
is independently kept for each video input. If Audio Follow Video is set to Off,
then the last setting you made for Audio Output Phase is used.
Dolby Framer Controls
9.0 Dolby Framer Sync
This parameter enables or disables automatic timing correction of the Dolby E
signal.
Off (default)
On
Offset
No Dolby E timing synchronization with vertical blanking. Normal
Audio Delay parameters are enabled.
Dolby E timing is auto-corrected to the minimum delay possible to
synchronize with the video blanking interval. Normal Audio Delay
parameters for the corresponding Dolby Framer Input channel
pair are disabled.
Dolby E timing is first auto-corrected to a nominal delay while
synchronizing with the video blanking interval.Then the delay is
further adjusted by the Offset specified in 9.2 Dolby Framer Offset
(Frames) and 9.3 Dolby Framer Offset (Samples). Normal Audio
Delay parameters for the corresponding Dolby Framer Input
channel pair are disabled.
In ON and OFFSET modes, if 1.0 Audio Input is set to Channel Map or Stereo Map,
the 6.x Audio Delay menus for that pair are hidden.
If the Dolby Framer cannot lock the audio signal to the video output, an alarm
is triggered. (This may happen with non-Dolby E signals, or with Dolby E signals
having an incompatible frame rate.)
The Dolby Framer is incompatible with audio Channel Map mode. It works only
with Stereo Map or single-source audio inputs capable of carrying Dolby E pairs. If
the Dolby Framer is enabled while the input source is set to Channel Map, Analog,
HDMI, or Dolby Decoder, an alarm will result, and the Dolby Framer status will be
shown as “Conflict”. Also note that Dolby Decoder is not a valid Framer source,
since the Dolby is already decoded into PCM audio by the time it reaches the
audio processor.
Dolby Framer status is available on the front panel Dolby Framer status menu or
the Status page of the web UI.
9.1 Dolby Framer Input
This parameter is visible only if 9.0 Dolby Framer Sync is set to On or Offset; the
parameter is hidden when 9.0 is set to Off.
The Dolby Framer Input can sync incoming Dolby E bit streams to the local
reference so they can maintain A/V sync when recorded onto VTRs or servers or
when passing through downstream facilities. You can set which pair of channels
