The SWITCH BOX MADI is a three input one output data switch designed to work with MADI based redundant playback systems. The unit takes in signals from up to 3 sources on BNC and allows the user to select a source for output. This might be a Main and Backup system as well as a third auxiliary line, perhaps for multitrack playback from a laptop.


The SWITCH BOX MADI features intelligent automatic switching. If the MADI signal stops on the active line, the SWITCH BOX MADI will check if a signal is present on the other line, and if it is, it will switch to that line automatically. Your show can continue and you can work out what the problem is. If you need to, you can bypass this feature quickly and simply to avoid unwanted switching.


Simplicity and reliability are the core ideas behind the design of the SWITCH BOX MADI. When you are trusting a single switch to handle both your main and redundant audio streams, it needs to be bullet proof. The SWITCH BOX MADI uses top quality tour ready components, features intelligent automatic switching, and will still pass signal on line A in a power loss scenario. Hundreds of productions all over the world in Arenas, Stadiums, Theatres and Churches, already trust That Little Box with their playback control, now you can have that same trust in your redundant audio switch system. 



The SWITCH BOX MADI is housed in a 1/2u rack mountable case with 4 holes on each side for fitting rack ears. Rack ears are not included. dimensions including connectors are: 210mm, 175mm, 45mm.
