The Boya BY-SM80 Stereo Microphone is a stereo X/Y condenser microphone, which produces broadcast quality stereo sound to your DSLR camera, video camera or audio recorder. The BY-SM80 is equipped with a high signal-to-noise ratio and is highly sensitive, providing greater control of your audio than the internal microphones integrated into DSLR cameras, video cameras and digital recorders. Both microphones can be turned 90 - 120 allowing you to achieve the best possible sound.
