The M 990 exhibits high sensitivity and with that an excellent signal-to-noise ratio. It combines modern large diaphragm capsule technology with the typical warm fully sound of tube microphones which is especially preferred by vocalists and soloists. The M 990 vacuum tube-condenser microphone is suited for difficult radio play recordings as well as supporting microphone for orchestra recordings. The time proven pressure gradient transducer of the M 990 uses a large diameter gold sputtered plastic membrane. The vacuum tube preamplifier is equipped with a pentode working as triode selected for its sonic characteristics.

The N 920.1 power supply provides the operating voltages for the vacuum tube-condenser microphone. It can be powered from a.c. mains with the primary voltage of 115 or 230 volts / 50 Hz or 60 Hz. 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 N 920.1 is equipped with the on/off-switch, the 7-pin Tuchel connector which powers the microphone and a 3-pin XLR connector with integrated voltage selector switch.

The complete system includes the M 990 microphone packed in a wooden case, N 920.1 power supply, C 92.1 microphone cable and an elastic suspension. The microphone is available in dark bronze.
