The Audio-Technica ATUC-M43H Conference Gooseneck Microphone is a fixed-charge, hypercardioid condenser microphone engineered for professional discussion environments. This microphone serves as a primary audio input for the ATUC-50 Digital Discussion System, supporting both wired and wireless configurations. The hypercardioid polar pattern focuses audio capture on the speaker, effectively reducing ambient noise and feedback.
The ATUC-M43H features a total length of 446.0 mm (17.56") and a head diameter of 20.0 mm (0.79"). A double-layer pop filter is integrated into the head to minimize breath noise and plosives during speech. The unit connects via a standard 3-pin XLRM-type connector, ensuring a secure and reliable interface with the discussion system base.
This microphone operates with a frequency response of 100 – 15,000 Hz, specifically optimized for vocal clarity. To maintain signal purity in modern electronic environments, the ATUC-M43H incorporates RFI-shielding technology. This shielding protects the audio signal from interference caused by radio frequencies.
For improved meeting management, the microphone includes a remote-controlled LED ring. This visual indicator allows participants and moderators to monitor the microphone's active status.
