dbx 376 Description
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.
