Professional audio, microphones and system integration

The Harmonai CM-310 is a professional-grade conference table microphone featuring a back-electret condenser capsule and an interchangeable polar pattern capsule design supporting three modes: cardioid, supercardioid, and omnidirectional. Whether for one-on-one meetings or multi-participant roundtable discussions, it captures each voice with precision. Its flat midrange response and moderate high-frequency boost ensure clear, natural, and authentic vocal reproduction.
The compact, elegant, and durable metal matte-finish base pairs with 48V phantom power and a gold-plated XLRM 3-pin male output connector to guarantee optimal audio signal transmission—ideal for conference rooms, broadcast studios, and remote video conferencing environments.
