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-tonoise 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.
