Hi Anders,

Each Digital coax or SpeakerLink output had 2 channels of audio data combined in to one signal (SPDIF, AES/ABU respectfully).
So the speaker is receiving two channels. However, the speaker is then configured to either use channel 1, channel 2 or in some instances (such as a daisy chained mono sub) both.

Dependent on application (i.e. which output from processor):
Channel 1 is: Left or Centre
Channel 2 is: Right or Sub

Regards,
Carl
