I don't know if this is the right area to post in, but I am looking for a device to transmit to lets say around 15-20 headsets from ideally a transmitter or two from a various points in the building, and doing so with out interference, if anyone know any company that provides such equipment. We need something to transmit the translation of the seminars being run in real time and a easy way to provide the people who require a translation with the equipment needed
