Interface for the simultaneous connection of 4 desktop microphone units BM2 to Leonardo Mini or to the multimedia player MP2120BT.

The activation of any microphone unit implicates the temporary exclusion of the remaining connected ones. Possibility to connect more than one interface in cascade, in order to increase the number of units to more than 4 (with the consequent decrease of 3 units each interface). Made in a metallic container, it has 4 inputs and 1 output on plug RJ45 connectors.
