Specifications

To improve the series of Black Hole microphones and provide wider choice for customers, JZ decided to launch the third version of Black Hole which is fixed cardoid polar pattern with a pad of -5db and -10db options.

The new microphone under the name Black Hole PE (BH-3) has a fixed cardioid polar pattern but after numerous requests from real life engineers as addition here comes a pad with options of -5db and -10db. It is used to avoid overloading mic preamps with high output mic signals such as when recording loud guitar amplifiers or cabinets and kick drums. As capsule of the Black Hole could handle 135db SPL this mic can manage also an operatic soprano at close range. Visually it looks similar to previous two versions (BH-1 – multi pattern, BH-2 – fixed cardiod mic) only it is in dark green color.
