UM 92.1S

NOTE: Comes in satin nickel and black matte finishes.  Includes power supply, cable, and metal carrying case.

Microtech Gefell's UM 92.1 S studio microphone features their M7 capsule, a pressure gradient transducer with 2 large-diameter gold-sputtered plastic membranes.

3 directional characteristics - omni-directional, cardioid and figure-8 - are selectable with a pattern selector switch that is mounted on the power supply.  The vacuum tube microphone shows a considerable signal-to-noise ratio and a high sensitivity.  The UM 92.1 S has the typical warm full sound of tube microphones that is commonly preferred by singers and soloists.  The direction of maximum sensitivity is radial to the grill (side addressed).

The vacuum tube amplifier uses a pentode working as high µ triode for its sonic characteristics.

The UN 920.1 power supply provides the polarization voltage for the capsule and the necessary DC voltages to the microphone amplifier.  It is recommended to set the heater voltage of the power supply to 5.8 volts for cable lengths longer than 50 meters.  The UN 920.1 can be powered from AC mains with the primary voltage from 115 or 230 volts - 50 or 60 Hz.

Mounted on the front panel are the pattern selector switch and the on/off switch.  Mounted on the rear panel are the AC mains connector (with choice of voltage), the 7-pin Tuchel connector which powers the microphone and a standard 3-pin XLR connector for audio output.
