Using the included shoemount adapter, this compact receiver mounts on your camera without adding much weight. The two included cables allow you to connect it to either the 3.5mm or the XLR audio input of any DSLR/mirrorless, camcorder, or recording device.

The EK 100 G4 features user-friendly menu operation with flexible control options. A daylight-readable LED display shows reception quality, battery status, and audio level.

Q: 4. What is the difference between A1, A, and G? What should I use if I'm filming mainly in Los Angeles?

A: Sennheiser breaks up the legal frequency range for wireless microphones of 470-608 MHz into three blocks. I would recommend the A1 block for Los Angeles, which is 540-516 MHZ. But all of the three groups have 1680 frequencies, and the ability to auto scan to find a clean channel.

Q: 5. Can I get a shotgun mic in this kit instead of the handheld?

A: The plug-on transmitter is designed to be used with dynamic microphones only, and will not work with a shotgun mic, which are condenser mics. The SKP500 will work with shotgun mics, but is not available in this kit configuration: https://www.bhphotovideo.com/c/product/1385730-REG/sennheiser_skp_500_g4_gw1_skp_500_g4_pro.html
