The AES/EBU Option card allows digital audio to be monitored by the MB-630. This option card is a fully self-contained digital to analog converter with two 4x1 balanced 110 ohm inputs to allow 4 x 4 channel monitoring
or 8 x 2 channel monitoring.
The digital inputs on the AES/EBU module follow the switching of the standard analogue input module which makes it possible to use a mixture of standard analog sources and digital sources.
