Native Instruments Audio 8 DJ with multicore cables!

Over 10 years old but still one of the best audio interfaces available to DJs. This is a full featured low-latency 8x8 audio interface with excellent phono preamps and 96/24 converters. This one has served me well and remains in great shape with minor cosmetic scratches but still functions absolutely perfectly. I've used it with Traktor, which it was designed for, but it will also work fine on any DJ or production software that needs a sound card. 8 RCA inputs (4 stereo pairs), 2 phono preamps, XLR Mic input, Headphones output (assignable to your cue channel), HP volume and Mic gain control knobs, and MIDI in/out (I've used the MIDI out to run a TD-3 alongside a DJ setup and it works great). 4 stereo outputs. Runs off USB power (and it's worked fine for me even through a hub) so no power supply needed. I will ship this unit along with the rare multicore cables which are perfect for switching between playing real vinyl and DVS timecode.

Note that if you're on MacOS you will need to jump some hoops to get it to work on newer machines, but it runs flawlessly on my 2015 laptop with High Sierra.
