SOUNDDEVICES 688 便携式多轨录音机+调音台

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.

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 redundant mics.

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.
