Dutch video production company United provided flawless audio support for the telecast of the abdication of Dutch queen Beatrice and the ascendance of her son Willem-Alexander through the use of many strategically placed microphones.

United was not allowed to have any visible microphones as part of the coverage. They solved the problem with shotgun mics and wireless lavaliers with belt packs taped to chair backs with gaffers tape.
