Professional audio, microphones and system integration

The Harmonai CM-250E is a desktop conference microphone designed specifically for professional meeting environments. It uses a back-electret condenser transducer and offers three interchangeable capsules: cardioid, supercardioid, and omnidirectional, enabling flexible audio capture for varying meeting sizes. With a frequency response of 40Hz–16kHz, flat midrange and gentle high-frequency lift ensure accurate vocal detail reproduction—every word remains intelligible and natural.
The unit features a metal matte-finish base—compact, elegant, and built to last—and connects via a gold-plated XLRM 3-pin male connector, powered by 48V phantom power. Its stable, low-noise signal transmission makes it ideal for conference rooms, auditoriums, and training classrooms.

The CM-250E is suited for any professional environment requiring high-fidelity voice pickup: in corporate meeting rooms, switch to the cardioid capsule for precise speaker isolation; in multi-purpose auditoriums, use the omnidirectional capsule for wider coverage; and in training rooms and remote video conferences, its low noise floor and high SPL handling deliver clean, quiet, and intelligible audio—even for remote participants.
