Providing you with a tube microphone preamp, a 3-band parametric EQ, and an independently accessible compressor based on their 162SL model, the 676 Tube Microphone Preamp Channel Strip from dbx boasts a Class-A tube preamp section that runs on 250V, giving you a range in tone from pristine to dirty. Its 3-band parametric EQ features sweepable mids, and a front-panel instrument input allows you to use the 676 as a DI.
