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.


Simplicity and reliability are the core ideas behind the design of the SWITCH BOX MADI. No data is decoded within the switch, it is just routed.  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, 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.


For best results the MADI output device should be clocked independently from the MADI stream being switched. If the clock source is the switched MADI stream switching will cause a short loss of audio.
