The N 149 A power supply generates the necessary operating voltages for the M 147 Tube, M 149 Tube or M150 Tube microphones. It works with all mains voltages from 100 V to 240 V, 50 or 60 Hz. Mains power is connected via a standard IEC 320 socket. The microphone connects via a DIN-8 connector.
The microphone signal is routed to a 3M XLR connector. The modulation output is balanced. The N 149 A provides the bias voltages for the microphone capsule, the filament voltage controlled by a sensor circuit and another voltage to generate the plate voltage and other necessary operating voltages in the microphone itself .
The unit produces a constant current performing a soft start of the tube. The KT 8 cable between microphone and power supply can be up to 100 m long. Interconnect cable lengths up to approx. 300m are allowed. The three available versions of the N 149 A differ only in their closed mains cable.
