Control Descriptions
Resample
Select to enable resampling of the selected stereo pair output from the de-
embedder. Resampling is used to seamlessly match the timing of audio
signals when the user-controlled delay is altered and is the default
condition. If resampling is deselected it is essential that the input and
output source is derived from the same source and the timing should not
be adjusted while on air. Without resampling, an adjustment in timing will
cause a number of audio samples to
be dropped or repeated.
A/B:Discrete AIP/AES Input Audio
Monitor external analogue or AES input channel status, invert channels, detect Dolby E
encoded channel pairs, mono and resample stereo pairs. Screen grab below shows
DIOP4 in the front piggyback position with two AES stereo pairs present.
Present
On when embedded channel detected.
Silent
On if the audio channel is silent i.e. consistently below the set
threshold.
Invert
Select to enable inversion of the de-embedder output for the
selected channel.
Dolby E
On if the channel pair has Dolby E encoding (AES inputs only).
Mono
Select to mono the channel pair. N.B. only the 1
st
channel of the
stereo pair is converted to mono, the 2
nd
channel is unchanged.
The mono output is gain corrected to maintain unity gain.
