For clear, interference-free speech in boardrooms, courtrooms and security monitoring stations, the Countryman Isomax 4RF Cardioid Gooseneck Microphone is built for professional installations. This gooseneck microphone combines industry-leading radio-frequency rejection with a cardioid polar pattern to focus on the speaker while rejecting ambient noise and RF sources. The 18" dual-flex gooseneck lets integrators position the capsule precisely for podiums, conference tables and surveillance monitoring points. Tuned for speech with a 500 Hz–10 kHz frequency response and a 270 ohm impedance, the Isomax 4RF delivers intelligible, low-noise audio for pro AV, security, and monitoring applications. The package includes a storage tube and windscreen for added protection during transport and installation, and the unit carries CE certification and a 1-year limited warranty.
