Audio input and output modules

The CAB 4n supports a number of different input and output modules. These modules are factory fitted into the four-channel bays at the rear of the unit.

Note: A CAB 4n may be ordered short loaded, that is, with some of the bays empty. In this case, blanking panels will be fitted.
