The Saramonic SR-VM4 is a high-quality super-cardioid condenser microphone for cameras and camcorders with an integrated 3.5 mm TRS mini-jack microphone connector. It features signal power adjustment, a high-pass filter, and high-frequency boost for optimal sound quality. A special new mounting system is responsible for noise and crackle suppression, eliminating unwanted sounds during camera or camcorder movements. Power is supplied by two AA batteries, and the microphone has a low battery indicator. A "deadcat" type wind muff is included, which reduces unwanted noises caused by air movement. Compatibility: Cameras, DSLRs, and camcorders with a 3.5 mm TRS mini-jack input.
