User manual JOEMEEK JM47

[. . . ] Fortunately for some other manufacturers in the world, the technology of the original company in East Germany became a part of the technology sharing policy of the Communist world, and it was taken up by some specialist manufacturers in the Far East. Today, fine microphones are still manufactured by the original company, and by the sharing of technology, we now have a number of products from China that are actually legitimate high quality microphones in their own right. For many years, Joemeek has been making occasional "one off"' capacitor microphones with varying degrees of success. [. . . ] The capacitor membrane is microfine `mylar' with gold sputtering, voltage polarised by phantom power. The microphone body is made of brass with double screening of the transformer. Connection is via screened balanced audio cable with 3 pin XLR connectors. Operation The JM47 is capable of handling very high sound volume levels so it can be used safely close to musical instrument amplifiers. If the amplifier sound is very loud, this may overload the microphone amplifier. It is also a very low noise microphone and suitable for voice recording to the highest quality. For voice recording, avoid singing directly into the capsule unless an efficient pop shield is used. Occasionally when close microphone techniques are used in the studio, an excess of low frequencies occur. The microphone is fitted with a high pass filter to minimise this effect. Using the JM47 The JM47 is supplied with an elastic shock mount system. Although the microphone is not particularly susceptible to sounds transmitted through the case, it is advisable to use this shock mount wherever possible. To further improve the performance of the mount, it is possible (but certainly not essential) to remove the wire clips (normally used to open the microphone holder), this allows the microphone more movement in the elastic mount. The response of the microphone is CARDIOID, this means that it is very much more sensitive to sounds from the front than from the rear. To get the best quality, be sure that the sound source is in line with the front of the microphone. To get the classic early capacitor microphone voice sound, the singer should sing very slightly across the front of the microphone at a distance of 150 to 200mm from the microphone. The microphone amplifier should be of the highest quality such as a Joemeek microphone amplifier. Problems Should the microphone accidentally become damp and fail to operate properly (start crackling, or go very quiet) then place it in a warm and very dry environment for 24 hours. The JM47 is extremely resistant to physical damage, but if the microphone fails to work after being dropped, it should be returned in adequate packing to the supplier. A double test and inspection system means that manufacturing faults are almost unknown but should any fault occur, it will be repaired (or replaced) free of charge excepting where the fault has been caused by physical damage. Care of Your JM47 Although the `mylar' membrane on the capacitor is more robust than the gold foil used by the German originals of the 1930s, it is still extremely fine and liable to damage if mishandled. [. . . ] NOTE, the microphone will not operate unless 48V phantom power is provided. The microphone should be powered up for at least one minute before it will operate correctly as the polarising voltage on the capsule needs to stabilise. Some background noise is possible during the first few seconds after switch on. [. . . ]
