Recording industry standard Neumann U87Ai capacitive recording microphone

Neumann U87Ai capacitive recording microphone U87 since 1967 had been recording industry standards, in a professional recording studio microphone, it to warm sound and well balanced character. Now, thanks to improved U87AI SNR increases 6 dB. The microphone is equipped with two large earthquake film, there are three points to sexual selection: Omni, heart-shaped point, 8 font point to. Behind the microphone, and a 10 dB attenuation switch, it can make the phone even if you pick up to 127 dB (the equivalent sound pressure 45Pa) sound signal will not cause distortion. The microphone can also be on the low frequency response attenuator to compensate for the proximity effect generated by the low frequency enhancement. Its frequency response range 20Hz-20kHz, rated impedance is 200 euro. Neumann U87Ai capacitive recording microphone U87AI very wide scope of application, it can basically be meet Studio, film, television, and other areas of various recording needs. It can be used as the main Orchestra band recording microphone, the microphone can also be used as directed on the separate instruments for recording. In various musical styles and voice for the environment, the human voice recording also U87AI behaved very well.
