Audio Routing
At the heart of TANDEM HD-21 is the sixteen input, eight output routing matrix. This will
allow any of the sixteen possible inputs, eight embedded channels and up to eight analogue or
digital audio inputs to be routed to any of the eight outputs for embedding or to be output via
output sub-PCBs. The final configuration will depend on the number and type of sub PCBs
fitted.
Note:
Front and Rear describes the position of the sub-PCB when fitted to the TANDEM HD-21.
Front nearest the board edge controls and extraction handle. Rear nearest the board
connector.
Note:
If an output sub-PCB is fitted to the front position its output will always follow
embedder D routing. Similarly a rear fitted output sub-PCB will always follow
embedder C routing.
