[. . . ] All Sennheiser P 48 models are designed for phantom powering with 48 V according to DIN 45596. the MKH 416 P 48 represents a combination of apressure gradient transducer and an interference microphone. [. . . ] This has the advantage that even with long cables induced interference signals can be disregarded. Also the internal noise produced by the microphone does not contribute to the total noise level. The microphones are fitted with RF filters which ensure that no high frequency signals from the microphone can affect the external circuitry and that the microphone itself is protected from high frequency disturbance. It is therefore not necessary, even under the most difficult conditions, to take special precautions, such as double screening of the cables or the provision of high frequency filters. Senn heiser condenser microphones are polarised according to DIN standard i. This should be considered when the amplifier input plug is being wired for correct phasing. 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. If a phantom-powered microphone is to be connected to such inputs it is generally necessary to use a transformer. The secondary of this audio-transformer may then be connected - one side grounded to the input. When it is normally intended for use with dynamic microphones, it can be necessary to reduce the output voltage from the microphone by means of a voltage divider. This should be built into the microphone cable at the amplifier input. [. . . ] Roll-off Filters MZF 15 and MZF 15-U This filter is built into the eonneeting eable between the power supply souree and the amplifier input. Connecting Cable KA 1 and KA 7 Tripie eonductor shielded cable fitted with 3-pin standard plug according to DIN41524 and 3-pin standard socket. [. . . ]
