DBX DBXPA2-V

The dbx DriveRack PA2 is a powerful and complete loudspeaker management system, designed to optimize and protect PA systems between your mixer and amplifiers. Tailored for both seasoned professionals and mobile sound engineers, it integrates all essential signal processing tools into one rack-mounted unit-making it an all-in-one solution for managing live sound with precision.

At the heart of the DriveRack PA2 are its advanced AutoEQ and AFS (Advanced Feedback Suppression) algorithms. AutoEQ quickly calibrates your room EQ and speaker levels with the help of an RTA mic, reducing setup time and eliminating the need for prolonged test tones. The enhanced AFS algorithm automatically anticipates and suppresses feedback without compromising your audio's tone. For added convenience and versatility, the unit features full mobile device control via Ethernet for Android, iOS, Mac, and Windows platforms, enabling intuitive wireless management from anywhere in the venue.

The PA2 offers flexible input and output processing, including dbx compression, graphic and parametric EQs, subharmonic synthesis, and crossover settings for full-range, 2-way, or 3-way speaker configurations. Driver alignment delays and limiting functions further ensure that your system remains safe and sonically optimized. Built to handle complex systems while remaining user-friendly, the dbx DriveRack PA2 is an indispensable tool for delivering professional-grade sound in a wide range of live sound environments.
