MBHO MBNM 648 PZ

A pressure zone microphone as pressure gradient receiver is used more and more where a discrete recor-ding is to be made in the highest quality. Direct sound is 3 dB more sensitive than diffused sound (due to pressure duplication the output voltage at a pressure 2 zone greater than 1 m is increased by 6 dB, the direc-tional diagram is halfed). Thanks to easy exchange of the capsules, the sound engineer has all applica-tion possibilities on hand. Using a hypercardiod cap-sule yields a remarkable range of results which are quite valuable for live broadcasting. Due to the remote impedance transformer, the PZM can use all MBHO capsules optimally and discretely. The microphone is mounted on a marble plate which has a non-slip pad at the back.
