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.

Quad is currently (as far as we are aware) the only scratch system to deliver real 3-deck and even 4-deck support. So, when 2 is not enough, just add another!

Loop Samplers, X-Filters, SVF Filters, Equalizers, Flanger, Phaser, Echo, Delay, Reverb... You name it, Quad has it. While offering all the crucial FX needed to elevate your mix to new highs, Quad also gives you full MIDI control over nearly all parameters, so you're always in total control of your mix even if you don't own an external mixer.
