Designed for mobile journalists, videographers, and vloggers, the black Comica BoomX-D D2 is an ultracompact, true wireless digital microphone system with two microphone/transmitters and one dual-channel receiver. It offers a complete solution for recording dialogue, interviews, and speech with two people talking simultaneously—directly to a mirrorless/DSLR camera or a mobile device.
The ultralightweight BoomX-D D2 consists of two ultracompact clip-on transmitters each with its own built-in omnidirectional microphone and a separate lavalier microphone. It also comes with a tiny receiver that mounts on and plugs into your camera with the included TRS cable. An additional TRRS output cable gives you the option to plug the receiver into any smartphone equipped with a headphone jack.
The system delivers reliable transmission with a clear sound at a distance up to 164'. The built-in rechargeable batteries provide up to 5 hours of operation. Versatile and extremely easy to use with simple controls, the BoomX-D D2 is well suited for content creators of any experience level.
- The two-channel receiver allows you to save space on your shooting rig by using a single receiver to simultaneously receive signals from the two mic/transmitters. The receiver features a belt clip, which also doubles as a shoe mount adapter for your camera. In the absence of a smartphone holder, the receiver can also be clamped to your smartphone using the belt clip.
- This plug-and-play system is easy to use. It comes pre-paired at the factory; connect it to your camera, turn it On, and you're ready to start recording.
- Dedicated gain buttons on the receiver allow quick and effortless adjustment of the signal level for each microphone independently.
- The receiver and the transmitters have a display that shows signal strength, audio level, mono/stereo configuration, and battery life.
- You have the option to switch between mono or stereo on the receiver: Recording in mono combines both microphones on both the left and right side of your audio track. Recording in stereo puts one person on the left and the other person on the right, allowing you to isolate each person's dialog and adjust each level individually later in post.
- The transmitters and the receiver are powered via a built-in lithium-ion rechargeable battery. They can also be powered via USB, even while in use, giving you near unlimited operating time.
- If your camera doesn’t have a headphone jack, you can monitor your sound via the receiver’s 3.5mm headphone output while recording to ensure that you are capturing a clean signal.
- Whereas typical analog wireless systems are susceptible to interference from TV and radio waves, the BoomX-D digital system avoids that by operating in the 2.4 GHz frequency band, which occupies frequencies beyond those of television, radio transmissions, and UHF wireless microphone systems.
- The system automatic changes transmission frequency to mitigate noise and dropouts at a line-of-sight distance of up to 164 feet. For optimal performance, environments with limited Wi-Fi/2.4 GHz traffic and minimal physical obstructions are recommended.
