The Countryman Isomax 4RF Gooseneck Microphone improves on a standard that can be found in many boardrooms, schools, courtrooms, meeting halls, etc.

The gooseneck microphone is designed to capture vocals with great clarity and detail while effectively rejecting nearby radio frequency (RF) interference from cell phones, computers and other electrical sources. Active Vibration Isolation uses a separate element to sense noise caused by vibration and shock and eliminates the noise on output.

The microphone itself delivers exceptional quality with a flat 70Hz to 18kHz frequency response and exceptional wind and breath noise reduction. The Isomax 4RF features a standard 3-pin XLR base and is an ideal choice for lectures, depositions, courtroom proceedings, and much more.
