Product Overview

Harmonai DM-268 is a professional supercardioid back-electret condenser microphone engineered for DSLR cameras, camcorders, and smartphone video recording. Its wide frequency response of 40Hz–16kHz and high sensitivity of -43dB ± 3dB accurately capture vocal detail while effectively suppressing ambient noise. The supercardioid polar pattern enables long-distance directional pickup — making it ideal for outdoor interviews, vlogging, and short-form video creation.

The lightweight body measures just 15mm in diameter, 163mm in length, and weighs only 205g, delivering near-zero added weight when mounted on a camera hot shoe. It connects directly via a standard 3.5mm audio jack and is compatible with popular DSLRs and camcorders supporting MIC input — including Canon 5D/7D/60D series, Sony CX series, Nikon D7000/D90, and Panasonic GH1.
