Congratulations on your purchase of the dbx 376 Vacuum Tube Channel Strip with digital capa-
bilities. For over 25 years, dbx has been the industry leader in dynamics processing. With the
introduction of the 376, the standard for channel strip processors has now been completely
redefined. Conventional channel strip processors are often limited in their ability to color and
control the tonal characteristics of a vocal or mic’d application. The 376 however, offers, a
Vacuum Tube Preamp section, a 3-Band Parametric EQ section, built-in Compressor and
De-Essing capabilities. In addition to the impressive list of effects available, the 376 also offers
the state-of-the-art proprietary dbx Type IV™ conversion system to offer the best characteristics
of both analog and digital applications all under one roof.

you have become familiar with the unit, we encourage you to experiment and find creative
ways that the 376 can help you optimize your specific application.
