Neumann BCM 104 broadcast condenser microphone
The microphone is technically in very good condition, has no errors or anything else and is only being sold as a new purchase. The invoice is no longer available, but it's already more than 2 years old anyway.
The microphone can be picked up in 12305 Berlin. Everything barrier-free. There are enough parking spaces and good bus/S-Bahn connections.
