Delivers auto EQ; RTA; dual 28-band graphic EQ; feedback elimination; sub-harmonic synth; 2x3, 4, 5, or 6 crossover; limiter on the output stage; presets matching the latest JBL speakers; and Crown power amps. Wizard setup help.
The DriveRack® PA provides state-of-the-art signal processing, while using a simple and intuitive user interface. This goal has been achieved by offering 2 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 6-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.
