Harmonai CM-612 hyper-cardioid condenser microphone product image

Product Overview

The Harmonai CM-612 is a professional hyper-cardioid back-electret condenser microphone, engineered specifically for stage performance and live sound capture. It achieves outstanding hyper-directional performance using the acoustic interference principle, precisely capturing the target sound source while effectively rejecting off-axis and ambient noise. The CM-612 supports both 48V phantom power and 1.5V AA batteries, delivering reliable operation indoors and outdoors. Equipped with a gold-plated XLR 3-pin male connector for low-loss, high-fidelity audio transmission, and featuring a wide, balanced frequency response of 40Hz–16kHz, it renders vocal reproduction natural and full-bodied.

Recommended Applications

Thanks to its hyper-cardioid pattern and flexible dual-power design, the CM-612 excels in stage performances, live vocal pickup, conference speaking, and outdoor interviews. In 48V phantom power mode, it delivers higher sensitivity and greater dynamic range (106dB), making it ideal for professional stages and recording studios. When powered by 1.5V AA batteries, it maintains up to 115dB maximum SPL handling—perfect for mobile outdoor filming and news reporting. Its 180Hz/12dB low-frequency roll-off effectively reduces stage low-end rumble and handling noise, ensuring clear, focused vocal reproduction.
