PA Performance Processor

The goRack is an easy-to-use portable speaker processor. Based on the industry-leading DriveRack Series, the goRack sits next to a set of powered speakers and provides powerful signal processing including Anti-Feedback (based on the AFS Advanced Feedback Suppression algorithm), Compression, Sub-Harmonic Synth and EQ. Each processing function can easily be enabled or disabled via top-level function buttons, and settings can be adjusted via goRack’s large data wheel.

goRack’s rear panel features combination 1/4”/XLR inputs that can be connected to either mixer outputs or microphones. When using a mic, the goRack's Mic/Line switch selects the proper input sensitivity and gain range, while dual gain controls on the top provide independent level adjustment. goRack’s 3.5mm Aux input allows for direct connection of mobile music players while XLR outputs interface with powered speakers.
