From Manufacturer
The EW 100 G4 2-Person Camera-Mount Wireless Combo Microphone System Kit from B&H is an extensive wireless mic system designed to deliver a compact, flexible, and reliable audio solution for a wide variety of applications including 2-person sit-down interviews, man-on-the-street interviews, documentaries, lectures, and more.
The kit offers two ME2-II omnidirectional lavalier mics with bodypack transmitters, a Senal omnidirectional handheld interview microphone with plug-on transmitter, two lightweight camera-mount receivers, a Vello mounting bracket, and a Kopul CMCS-1 microphone combiner. A waterproof SKB case is also included for transporting and storing the system.
Both receivers and the mic combiner can be mounted onto a single camera using the triple-shoe bracket. The two receivers plug into the combiner, which in turn plugs into the 3.5mm audio input of your camera. This allows you to record both mics using the single input of your DSLR, keeping your rig portable and compact. Alternatively, you can attach each system to its own camera during multi-cam shoots
