AKG CGN99 H/L Hypercardioid condenser Gooseneck Microphone

AKG CGN99 H/L Hypercardioid Condenser Gooseneck Microphone

The CGN99 H/L delivers a rigid yet responsive gooseneck design that positions reliably in fixed or mobile installations without drift or fatigue. Its 50cm length extends reach across conference tables, pulpits, and stage setups, while the hypercardioid polar pattern rejects ambient noise and side reflections—essential in houses of worship, conference rooms, and theater environments where clean, focused pickup matters.

Audio Performance

Built on condenser transducer technology, this microphone captures a 50Hz to 19kHz frequency response with 12 mV/Pa sensitivity and a 73 dB signal-to-noise ratio, ensuring articulate speech and detail even in moderately noisy spaces. The 125 dB maximum SPL handles elevated vocal levels without distortion, while the integrated 250Hz bass rolloff naturally tames proximity rumble and HVAC hum.

Design & Connectivity

The integrated XLR phantom power adapter accepts 9 to 52V phantom power from any standard mixer, eliminating external boxes and keeping cable runs clean. Its 13.5mm diameter and 160g weight mount securely without straining gooseneck brackets, while the 3-pin XLR output and 600-ohm output impedance ensure rock-solid compatibility with pro audio infrastructure.
