Digital-Audio
Interface boards for converting audio and ancillary data to the NEXUS 24-bit TDM format are available for a variety of digital formats. All digital inputs feature a double buffering facility. This avoids muting of digital audio signals whose phasing is out of tolerance with the AES-11 standard. All boards including output boards can be equipped with sample-rate converters for interfacing with asynchronous devices.
