This new professional all-in-one DJ system puts you in control of the music, like the conductor of an orchestra. Creating harmony between beautiful design and musical playability, it includes new and evolved features such as standalone 4-deck playback. All this combines to provide a spectacular DJ experience that you can harness to inspire your audience in any space or location. he OPUS-QUAD offers standalone 4-deck playback for versatile DJ performances. This means you can play 4 tracks on 4 different decks simultaneously, cue up tracks in advance, or leave a deck free for dropping requests into your set at a moment’s notice – all with just one unit. You can also assign a different color to each deck, which is matched by the jog ring illumination, so you’ll always know which deck you’re playing with.
