Microtech Gefell's UM 930 is well-suited for universal miking applications in broadcast and sound studios.  Other applications include vocalists, announcers, dialog pickup and as a spot microphone for recording guitars, keyboards, percussion, wind and string instruments.

The pick-up pattern is perpendicular to the direction of the microphone axis (side addressed).  The model number and pick-up pattern symbol mark the front of the microphone.

NOTE: Comes in satin nickel and dark bronze finishes.

Available for the UM 930 condenser microphone is an 1kHz level checking test signal for checking a complete sound system following the microphone.  The Soundcheck Tool is enabled when the polar pattern switching ring is placed midway between any of the polar pattern symbols for longer than 4-5 seconds, and the green LED illuminates.  The level testing signal takes the individual sensitivity of the microphone, pattern cardioid, and it is equivalent to a sound level of 74 dB.  This is 20 dB lower than the reference level at 1 Pascal, and assists in basic microphone setup during soundcheck.  The Soundcheck Tool reduces the need for frequent voice tests during setup in most cases.

The microphone features 5 pickup patterns: omni, wide cardioid, cardioid, hyper cardioid and figure-8.  A muting function works when switching between polar patterns.

When the microphone is ready for operation a green light-emitting diode (LED) inside of protection grid will indicate.  Acoustic influences that could result from the housing resonance and/or mechanical vibration are reduced by the robust construction and by a special fixture within the microphone's housing that dampens vibrations.

You can replace the black o-rings at the peripheral line of the switching ring with one or more colored rings.  Available colors include green, red and blue.
