Sound Devices 664 Field Production Mixer

The 664 Field Production Mixer is the new flagship in Sound Devices line of portable audio mixers. Building on the foundation of the popular 552 mixer, the intuitive 664 has six inputs channels and four output buses. All inputs and outputs are recordable to both CF and SD cards. This unprecedented amount of I/O connectivity and recording capability makes the 664 perfect for any production application.
