Neumann KMR82i 15.55" High Directional Shotgun Microphone, Nickel

The Neumann KMR82I 15.55" Supercardioid Shotgun Microphone uses a combination of a pressure gradient transducer and an interference tube. If the wavelength of the frequency is longer than the tube length, the microphones work as pressure gradient transducers. At higher frequencies they operate as interference transducers for lateral sound. Off axis sound sources are picked up with reduced level, but without coloration. Therefore, the microphones are well suited to record individual instruments of an orchestra. The pickup areas of several shotgun microphones may even overlap as, for example, during recordings on a large stage, without causing any problem.
