IT’S TIME TO CHANGE THE CHANNEL! The standard of excellence for channel strip processors has just been raised once again. From the world leader in digital signal processing comes the new 376 Tube Channel Processor with digital output capabilities. dbx® Professional Products has been paving the way for audio excellence for more than 25 years, and with the creation of the 376, the drive continues. The 376 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 376 is the perfect companion piece for recording and tracking vocals and mic’d applications in the analog and digital domain.

The 376 Tube Channel Strip w/Digital Output is the latest addition to the Silver Series family. The 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 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 376 lives up to the uncompromising standards of dbx Professional Products.
