Thank you for viewing. Manufacturer: Behringer Model: MDX2200 A 2-channel expander/gate, compressor/limiter dynamics processor housed in a 1U rack. Equipped with stereo link function and sidechain input, this is a high-cost-performance model with all the basic dynamic control functions. I am currently recording with a DAW, and this is an item being sold as part of the equipment cleanup from when I was previously recording multi-track at home. Regarding the listing, the operation has only been confirmed by powering it on. I have not checked it by connecting it to audio equipment. Please understand. Included items: Power cable
