Take the stage with Native Instruments' Traktor Audio 2 compact USB DJ audio interface! When you're ready to take your digital DJ-ing skills out to the club, you've gotta have a way to let the audience hear it. In other words, you've got to get the audio out of your computer and pumping through the PA system so you can get the crowd up and moving. And the Traktor Audio 2 is just the simple and affordable little box to get the job done for you. It connects to your computer via USB and features really high-quality 24-bit/96kHz converters, so you won't lose sound quality when you get the sound out of your computer and get things going in the club. Just connect the two 1/4" output channels to send your signal to an external mixer or straight to the PA. Easy enough! You even get two 1/4"-RCA adapter cables and a shielded USB cable with the Native Instrument Traktor Audio 2.
