Solo PRO SDI now supports up to 4 audio channels, when input via SDI. Output was specifically tested with SRT output. Below are some highlights about using this new feature.
Enabling 4 Audio Support
As of August 2025, you need a configuration change done to your Solo PRO SDI unit for it to support 4 Audio channels. A future Solo PRO firmware will include this configuration by default, but for now, please open a support case with your Solo PRO SDI serial number, requesting 4 audio channel support.
Once enabled, you can toggle on 4 Audio channel support in the Solo Portal. Click on the gear icon near the unit on the left hand bar:
And once your unit is modified with the configuration change, you will find a toggle bar that enables 4 audio support:
Once toggled, click the checkbox next to the Unit name to return to the normal portal dashboard:
Streaming with 4 Audio Channels
Once enabled, your chosen audio bit rate will apply to each group of 2 audio channels. You should now find in your SRT output, two groups of two audio channels.
