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
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
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.
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.
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.
high performance output transformer provides distortion- free modulation in the
lower frequency range and supports the distinctive vintage sound of this
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.
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.
