The SRPMIC2 is a lightweight, entry-level stereo cardioid microphone that records high quality audio to your DSLR camera or camcorder. It allows you to adjust the low cut filter to prevent rumble or other low frequency noise, and increase intelligibility of dialogue. The cold shoe mount allows you to mount the microphone to a camera or audio mixer. No battery is required, and the microphone connects directly to the camera via the included 3.5mm audio cable.
