The Sony ECM-778 is a professional XLR shotgun microphone designed for camera mounting and boom pole applications. Featuring a compact design (176 mm length, 102 g weight), it delivers high-resolution audio with a frequency response of 40 Hz to 40 kHz. The microphone employs a mono electret condenser capsule with a superniche polar pattern, providing excellent directionality and off-axis rejection. With a sensitivity of -31 dB, 40 ohm output impedance, and a dynamic range exceeding 117 dB SPL, it captures nuanced audio with exceptional clarity. The ECM-778 includes integrated low-cut filter, comes with foam and fur windshields, and requires 44-52V phantom power. Its brass acoustic tube and aluminum housing ensure durability while minimizing handling noise.
