Description

OVERVIEW Output Flexibility In complex, multi-camera productions, output flexibility is essential. The 664 can send its main left/right outputs to three cameras simultaneously. Two additional output buses, X1 and X2, appear on balanced TA3 connectors. AES3 digital outputs are individually selected to appear on the main XLR and multi-pin output connectors. Recording The 664 can record each of its inputs and its four output buses, for 10 record tracks. Recordings are saved to CompactFlash and SD cards. Recordings are either 16- or 24-bit Broadcast WAV files with extensive metadata. All popular production sampling rates are supported. When used with a CL-6 Input Expander, the 664 records 16 tracks, 12 inputs and four output buses. Integrated Time Code With the mixer's built-in, rock-steady Ambient time code generator, multiple devices can operate in synchronization. The 664 operates as either a time code master clock or its clock can be jammed from external time code. A helpful time code compare utility shows the difference between internal and external time code. Ease-of-Use The 664 was designed with knowledge gained from the industry's top engineers and from Sound Devices' expertise in portable mixers. Because sound engineers operate in fast-paced environments, important controls are on dedicated knobs and switches, while additional features are quickly accessed through the intuitive LCD-based menu control.

Internal: accepts five (5) NiMH, 1.5V Lithium, or Alkaline AA batteries. Note that run time will be very limited when using Alkaline batteries (30 minutes to one hour depending on settings). NiMH or Lithium batteries are the preferred type because of the approximate 2x to 4x run time compared to Alkalines.
