The AKG CBL99 is a Hemispherical Boundary Layer Microphone, designed to deliver superior results for a multitude of recording applications. The CBL99 is small, lightweight and easy to place. Since the transducer sits in a metal plate only 5mm (0.2 in) thick, the plate doesn’t interfere with or color the sound.

Frequency response is very uniform within its hemisphere, and it captures the “room sound” of an instrument very accurately. The CBL99 requires 9V – 52V phantom power. Its output is unbalanced via a professional XLR connector with switchable bass-cut filter.
