Drive your PA to a whole new level of performance with the DriveRack® PA Complete Equalization &
Loudspeaker Control System.The DriveRack PA from dbx Professional Products represents a complete
integration of the key elements that help ensure optimal loudspeaker system management in PA-spe-
cific applications. Capitalizing on the legendary 480 DriveRack technology, the DriveRack PA is able
to provide its user with top-tier, pro-level loudspeaker management specifications, yet still remain
appealing to the budget-conscious audiophile who requires a tried and true utilitarian workhorse.With
its all-inclusive, no-compromise design, the DriveRack PA has been systematically developed and
designed to grow with your system needs for years to come.
The DriveRack PA continues the legacy of DriveRack series, which has been created by the company
that has been redefining the standard of signal processing for more than 30 years. The DriveRack PA
was designed with the purpose and vision of providing state-of-the-art signal processing, while utiliz-
ing a simple and intuitive user interface. This goal has been achieved by offering two independent
channels of processing power with a linkable 28-Band Graphic equalizer, industry-standard dbx®stereo
compressor module, feedback eliminator and the 120A Subharmonic Synthesizer on the input, with a
six channel output system that includes parametric EQs, and Peak Plus™limiters (which are used to
provide protection against speaker blowouts) and alignment delay. These features combined with the
Wizard setup system, represent a methodical design that is guaranteed to deliver optimal, all-inclusive
processing in a completely scalable system. For more information, please visit: www.dbxpro.com.
