User manual JOEMEEK JM27

[. . . ] 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 output balancing is handled by a quality audio output transformer. The capacitor element is manufactured to the classic `concentric electrode' design which provides smooth extended frequency response. Quality is further enhanced by using dynamic feedback actually at the capacitor element. This original technique eliminates distortions which can occur when using this type of microphone for high volume levels. The capacitor membrane is micro fine Mylar with gold sputtering, voltage polarized by phantom power. The microphone body is made of machined brass; Connection is via screened balanced audio cable with 3 pin XLR connectors. Operation The JM27 is capable of handling very high sound volume levels so it can be used safely close to musical instrument amplifiers. Often the best sounding instrument are close miced, so it is good to take advantage of the JM27's high dynamic capability in these situations. It is also a very low noise microphone and suitable for low level or distant miced instrument recording to the highest quality. For voice recording, avoid singing directly into the capsule unless an efficient pop shield is used. Using the JM27 The JM27 gives a very true sound, meaning that the quality of a recording will depend on microphone placement, and of course, the performer and the surroundings. The response of the microphone is CARDIOID; this means that it is much more sensitive to sounds from the front than from the rear. It is important to remember this when micing up instruments that project sound from different parts; i. e. The mic placement will affect the sound quite a bit, so do plenty of experimenting before a take. Remember that different areas of an instrument often produce very different sounds, instrument micing is a highly Creative business and a good technique can make all the difference to the final mix. Once again, do plenty of takes, and don't be afraid to experiment. The JM27 is an extremely capable recording tool: used properly, professional results will be achieved. Pre amplification is also important to improve the microphone's sounds. [. . . ] With instrument recording in the studio though, unprotected use will give the best sound. All electronic equipment should be kept dry, but it is even more important to avoid any damp conditions when using high quality capacitor microphones. Damp can cause partial short circuits in the polarizing voltage, and this will cause crackling noises and low output.
