Product Overview

The Harmonai EM-2500 is a professional hypercardioid interview microphone, engineered using the acoustic interference hyper-directional principle to accurately lock onto target sound sources in noisy environments — delivering clear, pristine vocal capture. It supports dual power modes: 48V phantom power and 1.5V AA batteries, making it equally suitable for studio recording and on-location interviews.

The microphone features a back-electret condenser transducer, with a frequency response of 40Hz–16kHz for natural, full-bodied vocal reproduction. An intuitive ON/OFF power switch ensures straightforward operation. Its output uses a gold-plated XLRM 3-pin male connector, guaranteeing stable, low-loss audio signal transmission over long cable runs.

Weighing only 228g, with a slim shotgun form factor measuring Φ27 × 225mm, the EM-2500 is highly portable and versatile — perfect for handheld interviews, camera-mount use, or tripod mounting.

Recommended Applications

The EM-2500 is purpose-built for professional journalism and broadcast applications, including news gathering, film/TV production sound recording, documentary filming, sports event interviews, corporate event coverage, and outdoor podcasting. Its hypercardioid pattern delivers precise front-axis pickup even in challenging environments — effectively rejecting off-axis noise from crowds and wind. The dual-power design ensures reliable operation with 48V-equipped professional recorders or standalone battery-powered setups in remote locations.
