SMX-20 Compact High-Performance Directional Stereo mic with stereo mini-plug output cable, windscreen and shock-mount holder

Designed to work with today’s high performance DSLR cameras, the SMX-20 offers directional high quality stereo sound. At less than 5” long the SMX-20 is small in size only. Its wide frequency response, low noise and directional sound is a major step-up from the camera’s built in microphone. The SMX-20 comes complete with windscreen, LR-44 battery and shock mount holder with shoe. The attached output cable terminates with a 3.5 mm stereo mini-plug and connects directly into the camera’s microphone jack.
