AKG C547BL - Condenser Microphone

AKG C547 BL - Low-profile hypercardioid boundary zone microphone for tabletop, lectern, and stage

The AKG C547 BL is a professional boundary layer microphone designed to capture vocals with high intelligibility and lateral noise rejection thanks to its hypercardioid polar pattern . Its condenser capsule offers a frequency response of 30 Hz to 18 kHz , sensitivity of 8.5 mV/Pa (≈ −41 dBV), equivalent noise reduction of 22 dB-A and SNR 72 dB-A , with a switchable low-cut filter at 150 Hz to reduce foot slamming and low-frequency rumble on stage or desks. It operates on 9–52 V phantom power (approx. 2 mA consumption ) and is delivered with a 3-pin XLR connector and a 3 m fixed cable for quick integration into AV and sound reinforcement systems. Its ultra-low-profile ( 19 mm high) “no-crush” chassis withstands intensive use and blends seamlessly into meeting rooms, houses of worship, theaters, and educational settings. Compact dimensions of 120 × 185 × 19 mm and 160 g net weight with a matte dark gray finish.
