Transducer Type
Back-electret electret condenser
Professional audio, microphones and system integration

The Harmonai CM-350D is a professional condenser desktop microphone engineered for demanding conference applications. It features a back-electret electret condenser transducer and offers three interchangeable capsules — cardioid, supercardioid, and omnidirectional — to flexibly address varying meeting and presentation requirements. Its flat midrange response with a gentle high-frequency boost ensures clear, transparent vocal reproduction. The compact metal base with matte-finish surface delivers both aesthetic appeal and durability while effectively minimizing transmission of desk vibrations. A gold-plated XLR male (XLRM) 3-pin output connector, powered by 48V phantom power, guarantees faithful, authoritative voice reproduction for every speaking engagement.

The CM-350D is widely deployed in professional conference rooms, business forums, academic lectures, courtroom proceedings, and government agency audio systems. Its interchangeable capsule design enables flexible adaptation to diverse scenarios: omnidirectional for roundtable discussions, cardioid for solo presentations, and supercardioid for multi-speaker meetings. The 3-meter extended cable and gold-plated XLR interface ensure stable, reliable audio signal transmission; when paired with standard 48V phantom power, the microphone delivers rapid, plug-and-play deployment — making it an ideal choice for building high-fidelity conference systems.
