Product overview
The NEUMANN NM V is a classical pattern control unit with a mains transformer for operating the M 49 V and all vintage NEUMANN microphones utilizing the AC 701 tube, such as the older M 49 and M 249. It automatically switches between the 100-120 V and 220-240 V AC mains voltage ranges, and in the OFF position it draws no current.
To ensure a long life the tube is heated up gently, with current limiting, and very effective filtering ensures high-quality operating voltages with a minimum of residual noise. The audio signal is available at a balanced, floating XLR 3 output wired to IEC 60268-12 and IEC 61938: pin 1 ground, pin 2 audio (+ phase), pin 3 audio (- phase); with unbalanced inputs pin 3 must be connected to ground.
