FAQs

Do I need a computer to stream with the SR-20HD?

No, the Roland SR-20HD is designed for direct streaming to multiple platforms without the need for a computer. Just connect your AV devices and network.

Can I record my stream directly?

How many video inputs does the SR-20HD have?

It has three video inputs: two HDMI inputs and one USB video class input.

What audio sources can I connect?

You can connect up to four professional XLR microphones, line-level signals, a headset microphone, and digital audio from HDMI/USB sources, as well as audio from files on an SDXC card.

The SR-20HD features Adaptive Bitrate to minimize interruptions. It also supports mobile phone tethering (4G/5G) as a primary or backup connection.

How does the Safety Delay work?

Can I use the SR-20HD to play pre-recorded video or audio during a stream?

Troubleshooting

No video signal on output

Ensure all video source cables are securely connected to the correct inputs. Verify the selected input source on the SR-20HD matches the active source. Check HDMI cable integrity.

No audio on stream or recording

Confirm audio cables are properly connected to the inputs. Check that input levels are adequate and not muted. Verify the audio mix settings and ensure the master volume is up.

Stream is freezing or dropping out

Enable the Adaptive Bitrate function. Check your network connection stability and bandwidth. Reduce the streaming bitrate if necessary. Consider using mobile phone tethering as a backup connection.

SDXC card not recognized

Ensure the SDXC card is formatted correctly (FAT32 or exFAT). Use a compatible SDXC card (UHS-I U3 or higher recommended). Try a different SDXC card.

Cannot connect to streaming platform

Verify your network connection. Double-check the RTMP URL and stream key entered in the SR-20HD settings. Ensure the streaming platform is online and accepting connections.

Panel controls are unresponsive

Check if Panel Lock is activated. If so, deactivate it through the system menu. Restart the SR-20HD.
