While other Digital Vinyl Systems (DVS) enslave the DJ by forcing him to buy and to use specific hardware, Quad lets you choose your favourite soundcard - in fact any ASIO soundcard will do, as long as it's ASIO compatible and offers enough outputs and inputs for your needs (typically a soundcard with 4 mono inputs and 4 mono outputs is good for 2 decks).

Quad even goes a step further by eliminating the need for Phono Inputs on the soundcard, letting you connect your turntables directly to Line Inputs instead of Phono Inputs on the soundcard thanks to its integrated software RIAA Phono preamplification.
