- 6 inputs (4 HDMI and 4 SDI)
- Multiview output shows all the cameras and what you record/stream
- Remote controlled via network to a computer
- Audio input through the cameras (HDMI/SDI can also transport audio).
- Separate digital audio input (AES/EBU)
- Can output ready made stream in H.264. This signal can only be output to a streaming service with the Windows software mxlight (http://mxlight.co.uk)
- Recommend also Blackmagic Intensity Shuttle. With this you can record from the full quality HDMI output of the switcher on a computer. This way you can stream in low quality (if you have a narrow upload bandwith) and record in a higher quality.
