[. . . ] Besides its wide frequency response, the excellent pulse behaviour and the low sensitivity to handling noise this microphone features a frequency-independent cardioid characteristlc. [. . . ] It is theretore not necessary, even under the most difficult conditions, to take special precautions, such as double screening ot the cables or the provision ot high trequency tilters. Senn heiser condenser microphones are polarised according to DIN standard i. The difference between the two resistors should be ;;;;004% The current taken by Sennheiser condenser microphones MKH. In this case the microphone is simply connected via the power supply MZN 16 P 48 resp. In many cases, for example most home-tape recorders, the input socket is unbalanced. It a phantom-powered microphones is to be connected to such inputs it is generally necessary to use a transtormer. The secondary of this audio-transtormer may then be connected - one side grounded - to the input. When it is normally intended tor use with dynamic microphones, it can be necessary to reduce the output voltage trom the microphone by means ot a voltage divider.
