DYNAMICDIRECTIONAML ICROPHONEMD417 Speech/Music Switch Hold the microphone at arms length and bring it slowly back towards your mouth. If you listen to your own voice through headphones you will realize that your voice sounds duller the closer the microphones gets to your mouth. All directional micro- J phones show this increase of low frequencies at close miking. With the speech/music switch set to position "S" the } accentuation of the low frequencies can be eliminated. Therefore, the switch should always be set to position "S" when the distance between mouth and sound source is less than 20 cm. For recordings from a greater distance or when recording music switch position "M" is preferable. Introduction The MD 417 is a high quality dynamic directional microphone with a supercardioid characteristic. Robustness on the one hand and outstanding acoustical qualities on the other hand make the MD 417 an ideal choice for the keen audio amateur. The MD 417 features a high construction standard, which usually only appears in dynamic top class microphones. Through the use of a precisely adjusted shockmount for the inner parts of the microphone good handling noise suppression has been achieved. Thus the transmission of undesirable handling noise is largely suppressed. Furthermore, the MD 417 is equipped with a speech/music switch to cater for the various recording situations. Directional effect The MD 417 features a pronounced directionality, which is called supercardioid. The microphone "hears" best in a forward direction and gets more and more "deaf" towards the sides and the back. Therefore the micraphone must always be directed towards the sound source which is to be recorded. Due to the pronounced directionality disturbing noise coming from the sides and from tphheonbeacdkiaagreoneaflfleyctfirvoemly thseupbparcekss(e1d2.0°S) igpnroadlsucreeaocnhliyn~ /t1h2e(2m2icdrBo)of the voltage which would be produced by a signal reaching the microphone directly fram the front. Due to this characteristic the MD 417 is especially suitable for recordings in acoustically unfavourable environments. Connecting the microphone to tape recorders or amplifiers The connecting plug is simply inserted into the microphone input socket of your tape recorder or amplifier. Sennheiser ofters two different versions of the MD 417, which only differ by the connecting plug. J MD 417 LM 3 pin DIN-plug MD 417 K 6.35 mm jack plug Before you opt for one of these two models, have a look at the operating manual of your set to find out what kind of connector you need. If you should have any trouble when connecting the microphone, please contact your RTV-dealer. 6 Acoustical mode of operation. Frequency response Directional pattern. . .. ..
