To celebrate the 75th Anniversary of Neumann/Microtech Gefell (MG was the East German branch of the company) Gefell released a limited edition microphone in 2003, inspired by the UM57.
Only 75 of these microphones were made and these are serial numbers one and two.
These mics were very lightly used and in excellent condition.
I am the original and only owner.
This is a rare opportunity to get a true collectors item and piece of microphone history.
These mics are sold as a pair only and include everything:power supply, cables, elastic suspensions, windscreens.
The cases are also included.
Here is more information about the UM75 from the Microtech Gefell Brochure:
The UM 75 studio microphone features our M 7 capsule, made after classic technologies from the 1930s and renowned for its outstanding sound quality. This pressure gradient transducer uses two large diameter gold sputtered plastic diaphragms.
The capsules are selected for optimum polar response. Three directional characteristics, omni-directional, cardioid and figure-8 are selectable with a pattern selector switch mounted on the power supply.
The vacuum tube microphone shows a considerable signal-to- noise ratio and a high sensitivity. The UM 75 has the typical warm full sound of tube microphones which is especially preferred by singers and soloists.
The
direction of maximum sensitivity is radial to the grill, i. e. side addressed.
The vacuum tube amplifier is a time proven design using a pentode working as
high μ triode selected for its sonic characteristics.
The
high performance output transformer provides distortion- free modulation in the
lower frequency range and supports the distinctive vintage sound of this
microphone.
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 by your service work- shop
for cable lengths longer than 50 meters. The UN 920.1 can be powered from AC
mains with the primery 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 choise of voltage, the 7-pin Tuchel connector which powers the microphone and a standard 3-pin XLR- connector for audio output.
