Snip from the press release:
At the heart of the new MixPre-D are two studio-grade mic/line switchable inputs with limiters, high-pass filters and selectable phantom power. To accommodate the increasing variety of cameras and devices used in production today, the MixPre-D has incredible output adaptability and serves as a flexible, class-compliant USB audio interface.
The MixPre-D offers numerous analog output options including mic/line switchable balanced XLR, dedicated consumer mic-level on a locking TA3 connector (designed specifically for DSLR-type inputs) and an aux-level output on 3.5 mm connection. Digital outputs include balanced AES3 on XLR and USB audio connectivity for Mac OS, Windows or Linux computers.
