Capabilities Description
The Digital Audio Unit includes a generator, a reference generator, a main receiver, and a reference receiver. These four sections can
operate simultaneously, each at its own sample rate.
Interface Characteristics The generator always drives the Digital Out XLR, Unbalanced Out BNC,
and Optical Out connectors. The main receiver selects one of: Digital XLR,
Unbalanced In BNC, Optical In, or AES generator as its source.
The reference receiver normally selects the Digital Ref In XLR as its
source, except when the AES generator is selected as the main input, the
reference receiver input switches to the reference generator.
