Sound Devices 688 12-Input Field Production Mixer


The 688 is a production sound engineer’s dream come true - a portable audio powerhouse that incorporates multi-channel mixer, two powerful automixers, and integrated recorder plus optional SL-6 integrated powering and wireless system. By consolidating these functions, cabling requirements are significantly decreased, de-cluttering the sound mixer’s bag, increasing reliability and improving ease of use. With the SL-6 and SuperSlot-compatible receivers, the 688 gains complete Rx control and monitoring, plus RF scanning and frequency assignment, all from the 688's larger color LCD.



Inputs and Outputs
The 688 has six high-bandwidth mic/line inputs on XLR connectors, each complete with phantom power, high-pass filter, analog input limiter and variable pan. Six additional line-level inputs on TA3 connectors offer flexibility for more complex productions.

Routing Flexibility
All inputs are assignable, pre- or post-fade to its eight output buses, left/right plus Aux 1-6. The 688 can send its main left/right mix to three cameras simultaneously via transformer-balanced XLR and Hirose outputs.

Two Auto Mixers: The Choice is Yours
In keeping with Sound Devices' commitment to giving production sound mixers the tools they need to help them mix in increasingly complex production settings, the inclusion of the Dugan Speech System™, along with Sound Devices' MixAssist™, makes the 688 the 'go-to' automixing tool for field production applications. Automatic mixing is widely used in broadcast television applications, in dialogue recording for TV and motion picture production, and in house of worship (HOW) applications. It also is a good choice for teleconferencing, video trucks, and theater applications with multiple wireless microphones on stage. Dugan automixing takes over the nerve-wracking job of cueing mics in and out, freeing up the location recordist to pay more attention to the artistic balance.

MixAssist™
MixAssist automatically attenuates the level of inputs that are not active and helps maintain consistent background sound levels regardless of the number of open microphones. Comb filtering and phasing artifacts are also reduced when multiple mics pick up the same sound source by inteligently attenuating redundant mics. The end user can define the amount of off-attenuation MixAssist uses.

Recording
The 688 offers 16-track, polyphonic or monophonic broadcast WAV file recording to SD and CompactFlash cards. All common sampling rates are supported, including 192 kHz on up to six tracks. The memory cards can be set independently, recording either identical material for real-time backup, or combinations of WAV and MP3 files.

PowerSafe™
The 688 incorporates exclusive PowerSafe circuitry with smart sensing of available power sources, front panel warning indication of power loss, and an integrated 10-second power reserve that will, in the event of an inadvertent power loss, allow the 688 to safely stop recording, properly end all file operations, and then automatically shut down.

QuickBoot
Power on and start recording in less than two seconds. You never have to wait on sound.

Timecode and Metadata
The 688 features a world renowned Ambient™ timecode generator and reader supporting all common rates and modes. A helpful time code compare utility shows the difference between internal and external timecode. The 688 also generates sound reports and supports extensive metadata, via the front panel or attached USB keyboard.
