Sound Devices 664 Production Mixer

The 664 builds upon the features of the 552 Production Mixer and offers expanded input/output connectivity and recording capabilities. Its six input channels have dedicated controls for trim, fader, pan and PFL. The inputs and four output buses are all recordable, for a total of 10 tracks of recording.

Sound Devices’ 664 contains six range transformer-less preamps that accept mic- or line-level signals and include analog peak limiters, high-pass filters, input trim control and direct outputs on every channel. Featuring analog audio paths, the 664 also has digital capabilities. Inputs 1 and 6 can be selected as AES3 or AES42 inputs for digital microphones, each with its own SRC.

The analog output compliment includes four output buses. The L and R buses are on balanced XLR, 10-Pin, TA-3M connectors, or unbalanced on TA-3M or 3.5mm connectors. Auxiliary output buses X1 and X2 are available on balanced TA-3M connectors. Inputs and buses can be routed to four AES3 connections for eight digital outputs on the XLR and 10-pin connectors.

The 664 can record up to 10 tracks, 16– or 24-bit broadcast WAV files to SD and/or CompactFlash cards. All six inputs and its four outputs are individually selectable for recording, enabling the mixer to record all 10 channels of audio. With its dual card slots, content can be recorded to either or both cards simultaneously, with the added ability to assign individual tracks to each memory card.

Sound Devices also introduces a companion accessory, the CL-6 Expander. The CL-6 is specifically designed to add six analog line-level inputs to the 664 Production Mixer. With the CL-6 attached, the direct output connectors are available as recordable inputs, controlled by faders located on the CL-6 front panel. The CL-6 also offers additional LED output metering and duplicate-recording transport controls. With the 664 Production Mixer connected to the CL-6 Expander, users can now record up to 12 input channels and four outputs, for a total of 16 tracks.

The 664 features various connectivity options in addition to the main audio I/O. It has expanded return-monitoring capabilities, with three separate camera returns as well as a dedicated private line communications connection. The 664, like the 552, has a built-in slate microphone and tone oscillator, and includes a dedicated input for an external slate mike. The internal or external slate mike can be routed to either outputs or to the dedicated comm output. The 664 can build a private line communication with a comm return input, separate from camera returns.

Sound Devices’ 664 features an LCD menu that enables users to adjust input settings and offers the capability to see how an input is routed and connected when its settings are altered. The LCD display also enables users to activate the individual tracks that are to be recorded. The Sound Devices 664 features dedicated front panel controls for gain, trim and faders, as well as XLR connectors. The mixer is powered by five AA batteries or external DC power.

The 664 includes an Ambient-based time-code generator/reader for multi-camera and double-system sound applications. All common production time-code rates and modes are supported. The 664's top and bottom chassis panels are made from molded, metalized carbon fiber. The chassis panels are also gasketed for water resistance.
