Product Overview

Harmonai CM-31E is a back-electret condenser microphone engineered specifically for professional broadcast applications. It features an interchangeable capsule design, supporting free switching among cardioid, supercardioid, and omnidirectional polar patterns—enabling one microphone to cover diverse sound capture needs including voiceover, interviews, meetings, and studio recording.

Acoustically tuned with a flat midrange response and a slight high-frequency boost, the CM-31E delivers clear, transparent, and naturally accurate vocal reproduction. Its metal matte-finish body is compact, elegant, and robust—effectively minimizing desk resonance. The gold-plated XLR 3-pin male connector ensures optimal audio signal transmission, meeting professional-grade audio quality requirements.

Recommended Applications

The CM-31E is widely used in radio broadcasting, podcast production, conference speaking, voice narration, and online course recording—any professional voice application requiring clarity and fidelity. Its tri-directional interchangeable-capsule design ensures optimal pickup performance across acoustic environments: cardioid for solo presenters, supercardioid for effective ambient noise rejection, and omnidirectional for round-table group discussions.
