Yes. Delta link firmware version V1.31 introduced support for devices that use an additional Madi audio channel for control data. Some Madi equipped devices such as DiGiCo equipment use an additional audio slot in the Madi stream for transmitting their proprietary control/status information. In 56 channel mode, Delta Link now supports the format 56 Audio channels + 1 control channel. Delta Link does not use any of the third party control data. Other than setting the Delta link to 56 Channel mode, no other options need to be set to support this format.
