One glance at the Opus-Quad is enough to conjure a feeling of aesthetic satisfaction that might have more common ground with Herman Miller’s Eames Chair than a nightclub DJ booth, but its compelling profile is hardly just eye candy. Its slick composition includes performance-minded nuances, like the 5-degree slope of the wings or the thorough color coding made to keep track of controls over the 4-deck arrangement. A slew of I/O controls, rich FX, vivid displays, and premier technology make the Opus-Quad a controller that Sweetwater’s DJs feel is genuinely worthy of its name. From inspiring performance accommodations to high-quality AD/DA conversions and much more, this is a proper all-in-one controller that dares you to innovate.
