Up to 4 groups of audio may be embedded on SDI video. This control
selects the group ID of the multiplexed output audio. The input audio
will be put in this group.
The –A4 has only one stereo pair per group. A copy of this stereo pair
is placed in audio positions 3 and 4 within the group.
In addition to delaying the audio the same amount that the video is
being delayed (in the video frame synchronizer), additional user
requested delay may be added or removed with this control.
WARNING: Both the embedded audio AND the external AES audio
are delayed by this amount.
This option allows the user to pass or mute all the audio outputs during
loss of video.
The ADC Clip Level can be set to either + 18dBu or +24 dBu.
When the ADC Clip is set to +24dBu the input range is optimized for
peak audio levels up to +24dBu. (Default)
When the ADC Clip Level is set to +18 dBu, best performance is
achieved when input peak levels are below +18dBu.
Basic audio channel manipulation is possible with this control.
When set to Pass, both input channels are routed straight through.
When set to Swap, the two channels are routed to the opposite
channel output of the pair.
