The Alpha-Link will not allow the same MADI channel to be routed to both analogue and digital simultaneously (ie it is not MADI distribution).
The first 24 MADI channels feed the 24 analogue IO and the next 24 MADI channels feed the digital IO.
There is a diagnostic mode option to change the order to digital first and then analogue last.
To simultaneously monitor and record the same signal, you must transmit the same signal on MADI channels 1 and 25. 1 will go to analogue and 25 to digital (depending on the connection order noted prior).
