Overhead Cardioid Condenser Gooseneck Microphone

Overhead Cardioid Condenser Gooseneck Microphone

<p>The Astatic GCM113 is a professional overhead condenser microphone designed for discreet, ceiling mounted installations where clear, intelligible speech and natural sound pickup are required. Featuring a cardioid pickup pattern and a short flexible gooseneck, the GCM113 is optimized for low ceiling environments and precise microphone positioning. Its clean, low profile design allows the microphone to blend seamlessly into conference rooms, classrooms, houses of worship, and distance learning spaces while delivering consistent, high quality audio performance. </p>

<p>Engineered for modern installed sound systems, the GCM113 provides excellent RF shielding, effectively rejecting interference from mobile phones and other wireless devices common in meeting spaces. A built in 100 Hz high pass filter reduces low frequency noise while maintaining natural voice clarity, and the wide dynamic range supports confident speech reproduction with high gain before feedback. Powered by standard phantom power (DC 24–52V) and terminating in a convenient 3 pin quick connector, the GCM113 installs easily into standard electrical boxes for fixed or suspended ceiling applications. </p>
