Audix ADX18HC Miniature Gooseneck Microphone

22 Inch Hypercardioid Gooseneck Microphone For Focused Speech Reinforcement

The Audix ADX18HC is a 22-inch miniature hypercardioid gooseneck condenser microphone engineered for podiums, conference tables, lecture halls, courtrooms, and teleconferencing systems where maximum speech isolation is critical. Its extended length allows comfortable placement while maintaining tight, controlled vocal pickup for presenters in professional installed sound environments.

Hypercardioid Polar Pattern For Maximum Noise Rejection

Featuring a uniformly controlled hypercardioid pickup pattern, the ADX18HC provides tighter front-facing sensitivity and stronger side rejection than standard cardioid microphones. This focused response reduces ambient room noise, stage bleed, and feedback, making it ideal for high-volume PA systems, acoustically challenging spaces, and multi-microphone setups.

Wide Frequency Response For Clear And Natural Voice Reproduction

With a 40 Hz to 18 kHz frequency range, the ADX18HC captures speech with detailed articulation, balanced low-frequency response, and smooth high-end clarity. Fast transient response ensures consonants remain defined and intelligible, supporting professional speech reinforcement, live broadcast, conferencing, and installed audio systems.

Integrated Low Noise Preamplifier With XLR Output

The ADX18HC includes an integrated low-noise preamp circuit built directly into its base, delivering clean signal output via a standard XLR connector. Operating on 18 to 52 volts phantom power, it integrates seamlessly with mixers, DSP processors, audio interfaces, and commercial sound systems without requiring additional hardware.

Dual Gooseneck Design For Precise Microphone Placement

Constructed from durable machined aluminum, the ADX18HC features dual flexible gooseneck sections that allow accurate positioning of the capsule in front of the speaker’s mouth. The low-profile matte-black finish ensures a discreet appearance in boardrooms, worship spaces, and corporate installations while maintaining rugged reliability.

Interchangeable Capsule And Flexible Installation Options

The hypercardioid capsule can be removed and replaced with a cardioid capsule when broader pickup coverage is desired. The microphone includes a flange table mount for permanent podium or conference table installation and a foam windscreen to reduce plosives and breath noise. Designed, assembled, manufactured, and tested in the USA, it is built for long-term professional use.
