Audio Setup
Tone Frequency
This allows the frequency of the tone signal to be set.
The range of adjustment is from 100 Hz to
10 000 Hz in steps of 100 Hz. Preset is to 400 Hz.
Tone Level
This allows the amplitude of the tone signal to be set.
The range of adjustment is from -30 dBFS to
0 dBFS in steps of 1dBFS. Preset is to -20 dBFS.
Audio Delay
In addition to the delay compensating for the video
path through the system, an extra audio delay
period can be added to compensate for any video
delay introduced elsewhere in the system.
The range of adjustment is from –40 ms to
+160 ms in steps of 1 ms. Preset is to 0 ms.
Right Ident
When enabled the right channel will be identified
by the signal being muted for 0.5 second every 2.5
seconds.
Combine Group
Two pairs in the same group can be presented in
two valid but different ways in the Ancillary data
(combined or not combined).
The
Combine Group
function allows the user to
specify which one of these two alternatives the
NRS70 will use to embed the audio.
When ticked the group will be combined; when
cleared the group will not be combined.
Preset is to enabled (combine group).
This control should only be used if equipment
downstream of the NRS70 were only able to
recognize an uncombined group.
Ancil Status
This will display the status of the audio auxiliary
data. e.g. 1 - 2 - - - - - - - - - - - - A - B
Output A Status/Output B Status
This function displays the status of output A and
output B.
