MIXTRAX: MIXTRAX makes automatic remixing of tracks extra quick and easy. Simply connect your USB MSC or Apple iOS device (not compatible with Android) and listen as tracks are joined by various random sound effects in nonstop mix play to keep the groove going in full swing. MIXTRAX also features club-style illumination that enhances the mood with a dynamic dance club-like lighting effect. As MIXTRAX begins, lights start pulsing to the beat of the music, adding an extra level of entertainment. Choose among multiple patterns of lighting variations from sound pressure level or low-pass synchronization modes.
