The SR-AX100 from Saramonic is a passive 2-channel audio adapter designed to provide a compact solution for recording two signals to any DSLR or camcorder that has a standard mounting shoe and a built-in audio jack. It features left and right trim controls, and requires no power source.
It has three integrated mounting shoes for attaching mics or wireless receivers. Connect inputs via two mono 3.5mm (1/8") jacks or the single stereo 3.5mm (1/8") jack. Route the stereo 3.5mm (1/8") output to your DSLR or camcorder. The output can be set to mono or stereo via the M/S switch.
