They also had several cool new interfaces to show us. To go along with their 192kHz sampling rate is the 192 I/O Multi-channel Audio Interface, which not only lets you work with today’s current 96k sampling standard, but also sets you up for future standards up to 192kHz. The 192 has an I/O expansion bay allowing for enormous flexibility, plus they’ve included what’s called a Legacy Port for those loyal customers who have invested considerable time and money in previous Digidesign systems. Essentially, the Legacy Port lets customers connect 48k ProTools audio interfaces into the 192.
