Appendix C - MADI Split Monitoring 

 

The following diagrams show the number of MADI channels available – 

and the associated front panel displays – for each setting of MADI 

sample rate, Dante sample rate, channel count and split/redundant 

mode. 

 

The diagram to the right indicates the number of channel slots available 

for audio (or silence) in each operating mode. 

 

 

 

 

 

 

 

* SRC can be on or off. 

 

† In split mode operation the break between the channels is indicated by the dotted line – the first 

channel of the lower section becomes channel 33 or 29 and is the start of the secondary MADI port. 

The channel number mapping between MADI and Dante always follows the channel numbers.
