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. 

Four essential mastering tools that incorporate iZotope's pristine 64-bit processing, high quality algorithms, and immersive user interfaces are featured in the Mastering Effects Bundle.

The Multiband Compressor provides up to 4 bands of limiting, compression and expansion with real-time visualization of the dynamics within each band. The IRC Limiter Loudness Maximizer allows users to create an overall louder or fuller master by limiting the dynamic range and boosting the perceived overall level of the mix. The Analog EQ Parametric Equalizer combines 6 bands of adjustable bell filters and low/high shelf filters with analog modeling.
