Neumann N 149 A US Power Supply for Neumann M147, M149 and M150 Tube Microphones

Neumann's N149A power supply generates the necessary operating voltages for M147 Tube, M149 Tube or M150 Tube microphones. Mains power is connected through a standard IEC 320 socket. The microphone connects via DIN-8 connector.

The microphone signal is fed to a 3-pin XLR-M connector. The modulation output is balanced. The N149A supplies the bias voltages for the microphone capsule, the filament voltage controlled by a sensor circuit, and a further voltage to generate the plate voltage and other necessary operating voltages within the microphone itself.

The unit produces constant current, effecting a soft start of the tube. The KT 8 cable (not included) between microphone and power supply can be up to 100m long. Modulation cable lengths up to approximately 300m are allowed.
