DJs can leave them on or turn them off, which is nice.
The three LED light arrays automatically sync to your mix, flashing from the back of the Party Mix. Of course the most unique feature which makes the Party Mix a mobile ‘party-in-a-box’ is the built in light-show. This is a nice item for Numark to include that will help burgeoning DJs get used to mixing beats by ear instead of leaving entirely on Beat-Sync/Beat-Lock. The Numark Party Mix, somewhat surprisingly at this price-point, includes a built-in audio interface which means you have all the connections you need to send your mix of music to the speakers, while plugging in your headphones to preview the next track.
