- For a stereo channel, the minimum bitrate is 128Mbps.
- For surround 5.1, the minimum bitrate is 384Mbps.
- For surround 7.1, the minimum bitrate is 512Mbps.
Actions
In order to fix this issue, follow the instructions below:
- Open Source-Connect Pro or Pro X.
- In the settings section, check what channel you are using.
- Look for the bitrate setting.
- Depending on your number of channels, select the correct bitrate as listed above.
