User manual SENNHEISER MKH 416 T

[. . . ] The microphones susceptibility to wind and pop noises is low due to the relative high acoustical membrane pressure. The MKH 416 T can be employed as a microphone for soloists or for commentary purposes without using an additional popshield. the frequency response is maintained to have a slight increase of the high frequencies. [. . . ] the low capsule impedance leads to a high performance reliability 01 the microphones. Powering and Connection Sennheiser electronic introduced A-B powering, which was then standardised in DIN 45595. As with dynamic microphones, only two wires are required to connect the microphone when this powering system is being used. The operating current is led along the same wires as the audio Irequency signal, so that the circuitry in the microphone does not have to be connected to earth. Because 01 these earth Iree techniques the highest possible values of immunity Irom noise or disturbance are achieved. the connection 01 Sennheiser condenser microphones and dynamic microphones as weil is carried out using the principle 01 voltage matching. The advantages 01 this system are that neither impedance variations 01 the microphone output nor of the amplilier input exereise a noticeable influence on the total frequency response. The source impedance of the Sennheiser condenser microphones with A-B powering is so low (approx. 8 n at 1000 Hz) that an amplilier input with an impedance of at least 400 n will be suitable. Senn heiser condenser microphones produce relatively large output voltages, these can be up to 1 volt with maximum sound pressure levels. 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 litted with high frequency filters, which ensure that no high frequency signals from the microphone can allect the external circuitry, and also that the microphone itsell is protected from high frequency disturbance. It is, therelore, not necessary, even under the most difficult conditions, to take special precautions such as double screening 01 the cables or the provision of high frequency lilters. [. . . ] Special feature: If the plug and connector are connected together the battery eondition is indicated by a built-in signal diode. To prevent an unneeessary discharge of the batteries the battery adapter should be unscrewed from the microphone Dimensions when it is not in use. fitted with 9 mercury cells Mallory RM 625 , it provides a continous operation for 50 to 60 hours.
