The black U 87 Ai Condenser Microphone from Neumann is a large, dual-diaphragm condenser microphone offering three selectable directional patterns: omnidirectional, cardioid, and figure-8. A switch below the head grille allows you to choose the desired pattern, with a window above displaying the selected symbol. On the rear, a 10 dB attenuation switch enables the microphone to handle sound pressure levels up to 127 dB without distortion. Additionally, the low-frequency response can be reduced to counteract the proximity effect.
