This is a Universal Audio Apollo x6 Gen 1 Audio Interface with Thunderbolt 3. It offers 6 Inputs and 6 outputs. From the Universal Audio website: Elite-Class Audio Conversion with Two Unison Mic Preamps, HEXA Core Processing, and Surround Sound Monitoring I purchased it new from Sweetwater and paid $2,600. I am the only owner and it has been in a studio rack throughout in a smoke-free, pet-free environment under temperature as well as air purified room. The unit is in better than good condition but because of a slight blemish on the top cover while racking and a small scrape where a rack screw is I am listing this for $1,300. This unit comes with the original Power Supply and Packaging. Local inquiries are preferred but it can be shipped at a nominal additional cost.
