Audix CX112B Large-Diaphragm Condenser Vocal Microphone

The CX112B is a large-diaphragm condenser that delivers warm, silky vocals with a naturally smooth presence peak that flatters without coloring. The cardioid pattern gives you excellent rejection of room noise and feedback, making it feel responsive and controlled This laying down intimate vocal takes or performing live with confidence. Its presence rise sits perfectly in the vocal sweet spot, capturing clarity and detail while maintaining that rich, professional character that makes you sound larger than life.

Audio Performance

A pronounced presence peak centered around 10 kHz with approximately 6 dB of boost in the 8–14 kHz region ensures your vocals cut through a mix with natural clarity and definition. The cardioid pickup pattern provides tight off-axis rejection, while the included 10 dB pad handles loud sources and the bass roll-off filter controls proximity effect—essential tools for versatile studio and live use.
