Sound Devices Mix Pre-D

The MixPre-D sets a new standard for compact, high-performance portable audio mixers. Powered by only two-AA batteries or 10-18 VDC, the MixPre-D is designed specifically for audio professionals needing the most flexible connectivity in production applications where capturing great sound is important, but size and weight are a concern. The MixPre-D is also a class compliant USB portable audio hardware interface for Mac OS, Windows or Linux computers.
