This is a Blackmagic Design ATEM Television Studio Pro 4K. It's a live production switcher equipped with 8 independent 12G-SDI inputs. I think it's more compact and portable than the current integrated models. This is a used item. The main unit has minor scratches and sticker residue, but there is no significant damage and the condition is generally good. It comes with a PULSE hard case, which is convenient for transportation and storage. The items for sale are the switcher itself and the hard case only. The hard case will be wrapped directly in bubble wrap for shipping. This is highly specialized video production equipment. Please note that we do not provide any support regarding operating environments, usage methods, or equipment compatibility.
