The Neumann KM 145 comprises the KM 100 microphone body with the AK 45 removable capsule.
The AK 45 is a pressure gradient transducer with cardioid characteristic, similar to the AK 40. However, it has an acoustic bass roll-off that is useful during applications when subsonic and low frequencies may cause difficulties. The AK 45 is optimized for a flat low frequency response at a recording distance of 15 cm (“speech cardioid”).
This is a flexible miniature microphone system for professional users. A comprehensive selection of accessories permits adaptation to a wide range of requirements. Seven different capsules are available.
