Devices 688 12-Input Field Mixer
The 688 is a production sound engineer’s dream come true - a portable audio
powerhouse that incorporates multi-channel mixer, auto-mixer, 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. The 688 takes the finest
aspects of the acclaimed 633, 664, and 788T and creatively combines them with
new technology into an unrivaled production audio tool.
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.
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.
The 688’s powerful digital processing engine delivers 12-channel auto-mixing
capability using the most sophisticated algorithm on the market today.
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
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.
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.
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.
For a virtually cable free bag, attach this optional power distribution and
six channel wireless system. Its three slots provide powering and audio
interconnection between the 688 and slot-in receivers plus fully integrated
control and monitoring of SuperSlot™ compatible receivers. With its built-in RF
signal distribution, the SL-6
reduces the need for multiple antenna while its NP1 battery slot, USB charging
port, two 12 V isolated outputs, and two non-isolated direct battery outputs
provide powering for peripheral devices. Read more about the SL-6.
This optional input controller attaches to the bottom of the 688 and adds
six full-sized tactile fader control of channels 7-12, sunlight-viewable LED
metering and big, back-lit record and stop controls. When the CL-6 is attached
to a 688, the 688’s mini-faders, originally assigned as faders for 7-12, switch
to trim controls.
