DIGITECH QUAD-4

code: 850.DGT.010.RAC

The Quad 4 is 4 independent processors. Inside the Quad 4 is a multi-effects processor that is multi-talented and, while most of us can't do more than one thing at a time, the Quad 4 can do 4. The Quad 4 features 4 completely independent inputs and outputs that give you the power of 4 independent mono processors or 2 true stereo processors. Imagine the power to process 2 true stereo sources simultaneously without sacrificing control.

But true stereo is only the beginning. Imagine having 4 independent reverbs for vocals, guitar, keyboards, and drums, where each reverb can be optimized specifically to achieve the best audio performance for each application. And imagine a processor that gives you the power to create any combination of effects, in any order. And then multiply by 4. Check out the Quad 4. With its ingenious user interface, large custom display, and potent SDISC II¬ technology at its heart, the Quad4 is capable of not just replacing, but thoroughly eliminating the need for multiple, expensive, single-purpose processing units.
