The M 990 art is a large diaphragm tube microphone that, due to its unmistakable vintage sound is much loved by vocalists and instrumentalists alike.
The high sensitivity with its associated and outstanding signal-to-noise ratio are the result of modern, pionering, large capsule engineering. The pressure gradient transducer of the M 990 art uses a new
gold-sputtered PVC membrane based on well- established manufacturing technology. The tube amplifier is a low noise pentode valve operating in a triode configuration.
The valve is carefully selected for suitability by us in our own factory to ensure the long-term characteristics.
The M 990 art tube microphone is as much at home with demanding radio drama productions as it is as a spot microphone in orchestral recordings.
The microphone gets its power from the N 920.1 power supply unit, which is designed for mains supplies of 115 V or 230 V, at 50 Hz or 60 Hz. The heater voltage for the valve is stabilised. It is recommended that for cable lengths exceeding 50 m between the power supply and the microphone, the heater voltage, measured at the microphone, be set in the workshop to 5.8 V.
The N 920.1 is equipped with an on/off switch, a 7-pin Tuchel connector for the microphone cable,
a 3-pin XLR connector for the audio output, and a mains input connector with an integrated mains voltage selector.
The microphone is finished in a high quality, low reflection dark bronze with a precious pearl-gold plated ring.
