Microtech Gefell UM 930

The UM 930 is specifically designed to meet the needs of professional and semi-professional users who demand the highest quality of performance. This mic is 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.

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 five 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.
