User manual SENNHEISER MKH 406 P48

[. . . ] Besides its wide frequency response, the excellent pulse behaviour and the low sensitivity to handling noise this microphone features a frequency-independent cardioid characteristlc. Instead of the high polarisation voltage normally required, a high frequency capsule needs only a high frequency voltage of about 10 volts, wh ich is produced by a built-in low-noise oscillator (8 MHz). [. . . ] Pin 2 ot the Cannon-connector) goes positive with reterence to Pin 3. The amplitier input plug is being wired for correct phasing. According to the DINstandard the teed resistors should be 2 x appx. The difference between the two resistors should be ;;;;004% The current taken by Sennheiser condenser microphones MKH. 20000 Hz pressure gradient transducer card ioid 20 mV/Pa:!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. It the unit being used has a very high input sensitivity i. 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. This should be built into the microphone cable at the units input. [. . . ] Connecting Cable KA 7-U The cable is fitted at one end with a Cannon coupling and at the other with a Cannon plug connector. ) connecting the MKH 406 P 48-U to the power supply unit MZN 16 P 48-U.
