Sound Professionals choose dbx® DriveRack® products because these products provide the tools to ensure the sound systems sound their very best. The DriveRack 260 continues the heritage of unrivaled system and loudspeaker control, capitalising on the road tested and contractor approved nature of the DriveRack product line which has been created by the company that has been redefining the standard of signal processing for more than 30 years.

The DriveRack 260 was designed to provide 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, and a six channel output system with parametric EQs. PeakStopPlus® limiters are provided for protection against speaker blowouts. The DriveRack 260 provides full bandpass and crossover configurations along with independent output processing and the patent pending Advanced Feedback Suppression (AFS™).

These features combined with the Wizard setup system and complete DriveWare™ GUI control represent a methodical design that is guaranteed to deliver optimal, all-inclusive processing in a completely scalable system.
