The dbx 376 Tube Channel Strip w/Digital Output has taken the essential tools needed for channel strip processors and has greatly added to the feature list, making it an all inclusive toolbox that offers all of the effects required. With an effect menu list that includes such standard features as: a tube preamp section, 3-Band parametric EQ section, Compressor, De-Esser and digital outputs, the dbx 376 is the perfect companion piece for recording and tracking vocals and mic’d applications in the analog and digital domain.

The dbx 376 Tube Channel Strip w/Digital Output is the latest addition to the Silver Series family. The dbx 376 puts the best of both worlds into one affordable package by combining the warmth of the vacuum tube, with the proprietary dbx Type IV® conversion system. The 376 boasts many of the same features as other products in the Silver Series, such as +48V phantom power, a phase invert switch, and low cut filtering. In addition, the dbx 376 also offers digital output capabilities in both AES/EBU, and S/PDIF formats as standard features. The high impedance, 1/4" instrument input located on the front panel, as well as the mic/line switch, and 20 dB pad show our dedication to providing convenience in the studio. The LED meters provide a clear and concise visual of the signal processing at a glance. The rear panel includes both mic and line inputs and outputs, word clock sync input and output, insertion jack and digital outputs. Add selectable sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz; selectable dithering and noise shaping; and separate analog and digital output controls to this already impressive list of features, and we think you’ll agree that the dbx 376 lives up to the uncompromising standards of dbx Professional Products.
