The Sony ECM-674 is a cost-effective shotgun electret condenser microphone delivering excellent audio quality for both studio and outdoor recording applications. Featuring a flat, wide frequency response of 40 Hz to 20 kHz, it ensures clean, natural sound reproduction. With sensitivity of -36 dB ±3 dB (0 dB = 1 V/Pa) at 1 kHz and low self-noise below 17 dB SPL, it captures clear voice recordings even in loud environments. The microphone offers dual power options, operating via phantom power (40-52 V DC) or internal AA battery. Its compact, lightweight design (20 mm diameter × 268 mm length, 185 g without battery) provides optimal balance when mounted on camcorders. The integrated low-cut filter with two positions (M, V) efficiently reduces ambient noise.
