The Saramonic SR-AX100 is an ultra-compact, active two-channel audio mixer that allows you to input two microphones into a single 3.5mm jack. The SR-AX100 provides two XLR-1/4" combo preamp inputs with 48V phantom power for condenser and active ribbon microphones. Equipped with a built-in shoe, it can attach directly to your camera, a tripod, camera cage, and more with its 1/4-20 tripod thread. The SR-AX100's indented attenuator knobs make it easy to accurately set volume levels, and it records audio in one or two modes: mono, which blends the signals together; and stereo, which splits them between the left and right channels. The SR-AX100 provides a dedicated headphone out for monitoring your audio. And, it doesn't waste any space, providing you with three additional shoe mounts for lights, microphones, and wireless receivers.
