Mill River Music brings you a used Neumann M 147 Large Diaphragm Cardioid Tube Condenser Microphone w/ HSC and Power Transformer! In looking and testing this kit through, we found no issues with the microphone and other accessories physically or electronically; everything is in working order and sounds beautiful! Chasing vintage tones and pure sounds are within reach with this microphone, as the M-147 brings you Neumann's quality and flagship capsule found in their legendary U 47 but in a smaller housing!
From Neumann themselves:
"The M 147 Tube brings back the classic sound of Neumann’s famous tube microphones of the 1950s. The M 147 tube is a cardioid microphone using the same large diaphragm capsule as the legendary U 47 but combines it with an innovative tube circuit for lowest noise. Its transformerless output stage ensures superb performance at an attractive price."
