Product Overview

The Harmonai EM-865 is a professional-grade hypercardioid interview microphone built with a back electret condenser capsule, engineered specifically for news reporting, broadcast interviews, and documentary field recording.Hypercardioid polar pattern precisely captures sound from the front while effectively rejecting ambient noise from the sides and rear, ensuring clean, intelligible vocal recordings. Supportsdual power modes: 48V phantom power and 1.5V AA batteries, offering flexibility for both studio-based and mobile outdoor use.

The EM-865 delivers a wide frequency response of 40Hz–16kHz, a high signal-to-noise ratio of 70dB, a maximum input SPL of 130dB (with 48V power), and a dynamic range of 106dB — all meeting professional broadcast audio standards. Its compact Φ21×285mm body weighs only 134g (excluding accessories), enabling comfortable extended handheld operation.
