DBX DriveRack PA
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 utilizing 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.
