My ADI-2 Pro shows me the channel status "consumer" on the incoming AES/EBU signal of the SHD Studio. Is there a possibility to set the first bit in the AES/EBU signal to "Professional" instead of "consumer"?

Source link:

"Channel status information can be tailored for two different user groups: professionals and consumers. Applications within these two groups are very different and so are the channel status information associated. From there for each user group a subcode list (also called format) exists, defining how channel status bits have to be interpreted.

Consumer Area: Channel status data serve to prevent copying of copyrighted audio material in excess of one copy.

Professional Area: Here practice demands for reliable information about quality, type and source of the signal. Further information on synchronization is asked.

By agreement AES3 interfaces transmit channel status information in the professional format. Consumer format comes into operation with interfaces like S/PDIF and TOSLINK. Anyhow it is not made impossible to transmit channel status data via AES3 interfaces according to the consumer format. Consequence may beat the worst that a device will completely deny operation on the incoming audio data."
Quote end.
