JZ Microphones BLACK-HOLE

Taking advantage of modern technologies together with a handcrafted and tested approach, JZ Microphones proudly introduces the new multi-pattern studio microphone The Black Hole. This technically innovative microphone is extraordinary because of two independent, opposite-placed large capsules inside the compact head.

This original-looking design is very compact. It has a new stand holder system (damper) and a patented variable-sputtered diaphragm, using a specially mixed alloy for coating. The Black Hole is produces with three switchable polar patterns: Omni, Cardioid, Figure of 8.
