4 Stereo Channel Audio A/D Converter

The 4774 handles 8 analogue channels (4 AES/EBUsignals). Each module has four independent converters, each handling one AES/EBU signal (ie two analogue audio signals).

The digital connections are arranged directly to match the embedder module in pairs of AES/EBU signals.

The A to D utilises 20 bit analogue to digital converters.

The converters sample at 48 kHz for use with theDRX4778 embedder modules or when locked to analogue composite syncs. They may also operate at 32kHz, 44.1 kHz or 48 kHz for stand alone use when locked to a suitable AES/EBU reference.
 

The DRX4774 and its connector module occupy one slot in any of the DRX series rack frames.
