7.1–7.16 Audio Level
Ch1–16
These 16 parameters adjust the audio levels of the 16 audio channels ± 18dB dB.
Audio Output Phase
Controls
8.0 Audio Output Phase This parameter enables or disables individual audio phase adjustment of the 16 audio
output channels. When Adjust is selected, parameters 8.1 through 8.16 are then used to
adjust phase for the 16 channels.
If parameter 3 Audio Follow Video is set to On, the Audio Output Phase selection is
independently kept
for each video input. If Audio Follow Video is set to Off, a single
Audio Delay value applies, regardless of the video input. (This value is independent of
any of the values used in Audio-Follow-Video mode.)
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.
If parameter 3 Audio Follow Video is set to On, then A
udio 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.
Variable Adjustment of audio level +/-18 dB range in st
eps of 0.5dB.
Default: +0dB
Unity (default) Disable audio phase adjustments and set phase to unity.
Adjust Enable audio phase adjustments for the 16 audio channels.
Normal (default) Phase is unaltered as it passes from the input to the output.
Invert Phase is inverted as it passes from the input to output.
Off (default) No Dolby E timing synchronization with vertical blanking. Normal
Audio Delay parameters are enabled
On Dolby E timing is auto-corrected to the minimum delay possible
to sy
nchronize with the video blanking interval. Normal Audio
Delay parameters for the corresponding Dolby Framer Input
channel pair are disabled.
Offset Dolby E timing is first auto-corrected to a nominal delay while
synchr
onizing 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.
