There is a reason that Tour Sound Professionals and discriminating Audio Contractors choose dbx® DriveRack® products for their high-end tours and installs. The DriveRack products provide the tools that ensure that the system sounds its very best. With the introduction of the new 260, the heritage of unrivaled system/loudspeaker control continues. The 260 capitalizes on the road tested and contractor approved nature of the other products in the DriveRack line. The 260 provides full bandpass and crossover configurations as well as independent output processing and a full time RTA for live sound applications. Contractors will appreciate its control inputs for wall-panel logic control and the patent-pending Advanced Feedback Suppression (AFS™).

The DriveRack 260 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 260 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, PeakStopPlus® limiters (to provide protection against speaker blowouts) and alignment delay. 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.
