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:Audio Gain
Change the gain of the audio inputs by +/- 18dB.
Gain 1-4
In total there are 24 audio gain controls, one for each of the 16 channels of
de-embedded audio and eight channels of external audio. The gain controls
will give
±
18dB of gain relative to the input level up to the point where
digital clipping will occur.
Channel

Select the group of channels to control. The options
available will depend on the option sub-boards

show the rear piggyback options.
Default
