The Sound Devices 664 is an industry standard portable field mixer with the option of up to 12 inputs. It comes with six high-bandwidth, low noise microphone preamplifiers with phantom power, limiters, high-pass, pan, and direct outputs per channel. There are four output buses, Left, Right and Aux 1, Aux 2, transformer-balanced for freedom from ground loops and multiple output connectors, including dual multi-pin. The 664 has a built-in production recorder, and records all inputs and output buses: 16 record tracks total. All 12 input channels can now be used without the optional CL-6 input controller.

|Sample/Timecode Accuracy||± 0.2 ppm (0.5 frames per 24 hours)|
|Timecode and Sync||
Modes Supported: off, Rec Run, Free Run, 24h Run, External
Frame Rates: 23.976, 24, 25, 29.97DF, 29.97ND, 30DF, 30ND
Accuracy: Ambient generator, 0.5 frame in 24 hr
Time Code Input: 20k ohm impedance, 0.3 V - 3.0 V p-p (-17 dBu - +3 dBu)
Time Code Output: 1k ohm impedance, 3.0V p-p (+12 dBu)
Word In/Out: square wave; 10k/75 ohm, 1-5V p-p input; 75 ohm, 3.3V p-p output, at SR
External: isolated 10-18 V on locking 4-pin Hirose connector, pin-4 = (+), pin-1 = (-).
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.
