1RU Teranex Mini Rack Shelf for 19" racks from Blackmagic Design. This shelf is well-suited for road cases as well as equipment racks. Fits all Teranex Mini Converters, ATEM Television Studio HD, Web Presenter, and HyperDeck Studio Mini. Teranex Mini are designed to be racked side by side, with three converters fitting in 1RU, six in 2RU, and nine in 3RU. When multiple units are racked side by side, variable speed fans pull from one unit into the next to facilitate optimal air flow. If a fan fails adjacent Teranex Mini will increase fan speed, to prevent overheating! And because they're small and lightweight, you can even mount them in the rear of a rack or road case!
