Native Instruments Audio 4 DJ in Excellent Condition! Here's a little more info about the unit:
"The Native Instruments Audio 4 DJ Interface is a DJ audio interface for the Mac and Windows operating system. It features 4 line/phono switchable inputs, 4 high-gain outputs, a headphone jack for discrete monitoring and cuing and a USB 2.0 connector. Professional standard 24-bit / 96kHz audio resolution delivers pristine audio performance on demanding nightclub systems.
Low-latency driver integration results in quick software response with external controllers, CD decks and turntables. Illuminating LEDs provide a clear indication of signal flow in order to avoid mis-wiring in dimly lit clubs and DJ booths. The interface also features ground terminals and allows DJs to directly connect turntables for use without an external DJ mixer or for digitizing old vinyl directly to software.
DJs of all genres will appreciate the rugged, all metal construction and the pristine high audio output of its 24-bit / 96kHz resolution.
