Condenser microphone with switchable polar pattern and shockmount
JZ Black Hole (BH-1)
It is very handy and compact with an absolutely original 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.
- Multi - pattern condenser: cardioid, omni, figure-8
- Class A discrete amplifier circuit
- Two (!) opposite placed, independent, large, true electrostatic capsules inside the compact head
- New special capsule with single, less centre tap diaphragm and adjustable backplate.
- Patented variable sputtering of diaphragm, using specially mixed alloy for coating
- Integrated capsule shockmount. [http://static.zoovy.com/img/purewave/-/images/specs]
