First choice for loud sound sources

• solid-state successor of the legendary U47
• was developed between 1969 and 1972 under the leadership of the famous Neumann chief engineer Gerhart Boré (U67, SM23, U87 etc.)
• due to the complex circuit design with a huge output transformer the U47 fet handles even the highest SPLs (up to 137 dB, with attenuation up to 147 dB!)
• equipped with the same type of capsule (K47) as late U47s
• cardioid polar pattern
• switch for pre-attenuation (-10 dB), output attenuation (-6 dB) and low-cut (140 Hz)
• manufacturing period: 1972-1986, in October 2014 Neumann has resumed the production of this microphone

Favourite applications: similar to dynamic microphones: in front of the bass drum (often combined with a dynamic microphone in the BD), bass amp, brass instruments, upright bass, vocals (especially male voices)
