Microtech Gefell M990
Brand: Microtech Gefell
The M 990 is renowned for its high sensitivity and excellent signal-to-noise ratio. It combines modern large diaphragm capsule technology with the typical full-bodied sound of tube microphones that are preferred by vocalists and soloists. The M 990 vacuum tube condenser microphone is well-suited for difficult radio play productions as well as a supporting microphone for orchestra recordings.
The new pressure gradient transducer of the M 990 uses a large diameter gold-plated plastic diaphragm. The vacuum tube preamplifier is equipped with a pentode working as a triode selected for its sonic characteristics.
The N 920.1 power supply provides the operating voltage for the vacuum tube condenser microphone. It can be powered from AC mains with a primary voltage of 115 or 230 volts / 50 or 60 Hz.
For cable lengths over 50 meters it is recommended to have your service provider set the heater voltage of the power supply to 5.8 volts. The N 920.1 is equipped with an on/off-switch, a 7-pin Tuchel connector that powers the microphone and a 3-pin XLR connector with integrated line voltage selector.
The M 990 is packed in a wooden case and comes with power supply , connection cable C 92.1 and elastic suspension EA 92.
The microphone is available in a dark bronze finish.
