If you do not hear audio output from your V-1SDI, here are some troubleshooting tips to help determine the cause of the issue:

 

If you do not hear audio on your Program SDI output, check the firmware version. If you have an early version, you need to update to the latest version to fix this issue.

 

If you have firmware 1.570 or later and still do not hear audio on your Program SDI output, try the following:

 

The easiest way to begin troubleshooting is with a factory reset. Please follow this guide to reset your settings and test again:

• V-1HD: Returning Settings to the Factory Default

 

Press the [ AUDIO ] button to open the audio menu, which is viewable on your MULTI-VIEW output.

You an also use the free RCS software to adjust settings. The software is also useful during production, as you can mix audio without having to open the menu.

 

On the first page of the audio settings, check the levels for your Inputs and Master Output. The default value is 0.0dB.

If it is -INF, then it is muted.

 

Use the [ DSK ] and [ AUTO ] buttons to highlight the setting you want to adjust, and then use the slider bar to adjust the value.

 

On page 2, check that Audio Follows Video is turned OFF. If any inputs have it enabled or assigned, then the switcher will only output the audio when that source is selected.

Once your settings are confirmed or reset, you should hear audio from your analog and digital sources on all outputs.

 

If you do not, there may be a wiring or signal routing issue.

 

If outputting to an SDI monitor, go into the monitor settings to confirm that it is monitoring audio on SDI embedded channels 1 and 2. Some monitors allow you to choose a different pair or channels to monitor the audio on.

If outputting to a SDI video device like a streaming encoder, go to Page 3 of the video setup menu, and change the 3G SDI MAPPING setting. It's possible your destination device does not support both Level A and Level B, so this may resolve your issue.

 

If none of the above solutions work, please contact support and we can troubleshoot further.
