The Black Hole BH-1
Taking advantage of modern technologies together with handcrafted and tested approach, JZ Microphones proudly introduces the new multi - pattern studio microphone Black Hole. The Black Hole is an absolutely technically innovative microphone. It is extraordinary because of two independent opposite placed large capsules inside the compact head.
It is very handy and compact with absolutely originally looking design. It has new original stand holder system (damper) and patented variable sputtering of diaphragm, using specially mixed alloy for coating. The Black Hole is produced with three switchable polar patterns (Omni, Cardioid and Figure of 8). Designer of Black Hole is sure that the result will agreeably surprise every user.
