True stereo effects
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 four. Check out the Quad4. With its ingenious user interface, large custom display, and potent S-DISC 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
Several new effects including: Reverse Delay, Time Warp, Vocoder, Spring Reverb, Sampler
Effect Configuration Selection within each program
Maximum Delay time of 5 Seconds
Dozens of New Programs
