With the integrated ProTools recording software, the Digidesign 96 I/O Digital Recording Interface can record up to 16 pro-quality tracks to your hard drive. Serious musicians who want to take their recording to the next level use the 96 I/O because of superior features that include eight channels of 24-bit analog recording and eight channels of ADAT I/O. Something musicians also love is that this unit features an expansion port that effectively doubles its recording capabilities. When another Digidesign interface is connected, it becomes possible to record up to 32 tracks that can be mixed down to sound like they were produced in an expensive studio. High-definition I/O on this unit offers crisp and clear audio quality that must be heard to be believed.
