Sound Devices has released a further update for its 664 Production Mixer, bringing six additional line-level inputs – to total 12 analogue inputs and 16-track recording.

Version 2.00 enables the 664 to record 16 track files, which include all 12 inputs plus its four outputs, without requiring the CL-6 Input Controller – the CL-6 provides hardware fader control of Input 7 to 12. Revision 2.00 also brings additional LCD metering modes to support the expanded input capability. Three menu-set metering modes are selectable from the front panel meter button. Meter modes offer combinations of input and output levels.

The 664 records 16-track monophonic or polyphonic broadcast WAV files or stereo MP3 files to SD and/or CompactFlash cards. All inputs and outputs are individually selectable for recording, and feature up to three seconds of record pre-roll. With its dual card slots, the 664 can record content to either or both cards simultaneously, with the ability to assign different tracks to each memory card. With cards not optimised for multi-channel monophonic file recording or if the monophonic ten-track limit is exceeded, a warning message is displayed on the LCD when starting a recording. In addition, when formatted in the 664, SD cards 64Gb and larger are automatically formatted as ExFAT (in accordance with the SD Association’s recommendation). All CF cards and lower-capacity SD cards remain FAT32.

The LCD Daylight Display mode incorporates a daylight-specific colour scheme and solid-bar metering option for improved readability in direct sunlight. In addition, it includes a high-precision, Ambient-based time-code generator/reader for multi-camera and double-system sound applications.
