dbx 676 Tube Microphone Preamp Channel Strip

THE PEDIGREE OF PROFESSIONAL AUDIO.
The 676 represents all of the best of dbx’s more than 40 years of dynamics processing.

The 676 offers a pristine high-voltage, Class-A tube preamp section that runs on 250 volts, so your signal can be as crystal clean or dirty as you need it to be. The 676 also incorporates the compressor/limiter design from the highly-sought after dbx162SL, as well as a 3-band parametric EQ with sweepable mids.

The 676 provides audio professionals with the perfect channel strip for recording and live applications alike with its military-grade build, vintage-inspired controls and VU metering.
