Types of DIâs; active DI units and passive DI units. Passive DI Units. A passive DI unit typically consists of an audio transformer used as a balun. Typical turns ratio is about 500:1, to match a nominal 50 kÎ© signal source such as the magnetic pickup of an electric guitar to a 100 Ï input.
remains of AFB-infected brood are principally from older larvae that die in the upright position, most often after the brood cell has been capped, but larval remains can also be found in open cells. As the infection progresses, cell cappings harbouring dead brood appear greasy, dark-ened and become concave and punctured with small holes.
