Stereo ISA 220 Units
It is possible to send audio from an ISA 220 to an A/D card in a second ISA 220 via the EXT A/D input. This configuration creates
a stereo/dual mono record channel with only one A/D Card.
Stereo control of Dynamics section
The example above also shows how to link two ISA 220s together, allowing them to be used as a stereo/dual mono record
channel. The stereo channel can then be routed to a single optional ISA 220 Digital Output Board allowing A/D conversion of the
stereo signal.
