Like neww Steinberg MR 816 CSX. Although it shows the box has been opened, I am selling like new because the unit was never used. I was gifted with a presonus studio live 16 channel mixer before I ever got a chance to use it. I will include a Full version of Cubase 5 instead of AI4. An elicense key will need to be purchased to use Cubase 5. They can be bought from Steinberg for $35. If you do not need Cubase software. I will accept a lower price. Buyer will NOT be disappointed!!!Payment is expected within 24 hours of listing close and will be shipped within 24 hours of recieving cleared payment. I will ship to continetal U.S. ONLY. Buyer will NOT be disappointed!!!
