First, the analog output is digitized using 24-bit A/D converters.
This serial digital data is then routed to a digital audio transmitter. This transmitter handles all "packeting" of the digital audio. This chip (transmitter) can put audio data into AES/EBU format as well as S/PDIF format. The format is chosen by the position of a jumper on the Digimax controller card: Pro mode or Consumer mode, AES/EBU (standard) or S/PDIF respectively. The transmitter also handles all the status and user (user bits are unused in the Digimax) bits that are stated in the digital audio standards. Finally, the data is routed through signal transformers that are impedance matched by setting 2-pole jumpers to the correct
position for each of the digital audio formats.
