238 X75HD/X75SD Installation and Operation Manual
Appendix B: Troubleshooting
Not passing the embedded audio
Without the optional audio submodule, the SD-SDI with embedded
audio will pass through the SD-SDI output. The HD-SDI signal with the
embedded audio will not pass through the HD-SDI output.
When the video frame sync repeats or drops a frame, or if there is a
hot-switch, there will be a disturbance in the embedded audio data
stream. This occurs with any video frame sync that passes embedded
audio with no embedded audio processing.
When the X75SD unit has no audio submodule installed, the default
factory setting will not allow the audio to pass. To change this setting,
follow this path:
Video Setup>Processing>SD TSG & Slide>Keyer TSG Insert =
None
Additionally, there is an implementation issue with X75 version 1.6.100
and below.
When the frame is rebooted or the Video Input source is switched, the
Keyer TSG Insert parameter follows the selected input video source.
In order to pass the embedded audio again, this parameter must be set to
None again.
This issue will be addressed in the subsequent software release.
