Designed for mobile journalists, videographers, and vloggers, the Comica BoomX-D MI1 is an ultracompact, true wireless digital microphone system with one microphone and a dual-channel receiver that can also be used to receive a second microphone (available separately). It offers a complete solution for recording dialogue, interviews, and speech with one person talking—directly to an iOS smartphone or tablet.

The ultralightweight BoomX-D MI1 consists of an ultracompact clip-on transmitter with its own built-in omnidirectional microphone and a separate lavalier microphone. It also comes with a tiny receiver that mounts on and plugs directly into the Lightning port of your phone. To ensure that you are capturing a clean signal, you can monitor your mic via the receiver's 3.5mm headphone output while recording.

The system delivers reliable transmission with a clear sound at a distance up to 164'. The transmitter's built-in rechargeable battery provide up to 5 hours of operation. Versatile and extremely easy to use with simple controls, the BoomX-D MI1 is well suited for content creators of any experience level.

• The transmitter is equipped with a built-in microphone and a 3.5mm mic input that accepts the included lavalier microphone.
• For a truly wireless experience, the transmitter can be clipped on clothing without having to wire yourself or your talent. You can also hold the transmitter in your hand and use it as a handheld microphone.
• The On/Off switch doubles as a mute button.

• For a more discreet setup, use the small lavalier microphone, which can be easily concealed away from the camera's eye.

• This plug-and-play system is easy to use. It comes pre-paired at the factory; connect it to your phone, 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 transmitter has a display that shows signal strength, audio level, and battery life.
• The transmitter is powered via a built-in lithium-ion rechargeable battery. It can also be powered by an external charger while in use, giving you near unlimited operating time.
• The receiver is powered via the phone.

• If you need to expand your system with a second microphone, the two-channel receiver allows you to save space on your shooting rig by using a single receiver to simultaneously receive signals from two mic/transmitters.

• 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.

Q: 1. Can you use a USB-C to USB3 adapter for a PC without USB-C?

A: Yes, you can use an adapter like the Angelbird USB Type-C Female to USB Type-A Male Adapter (B&H # ANUSBAC) to connect the Comica Audio wireless receiver to a standard USB Type-A port on your computer.

Q: 2. How can we use this for zoom meeting plugged into a phone? There is no audio so cannot hear others, but they can hear me.

A: Try starting the app on your iPhone using the built-in mic (without connecting the wireless system). Once the app is already running, then connect the wireless receiver to the iPhone. That may work. You will probably need to use headphones to hear the others in the Zoom meeting. Apple iOS devices may not work with an external mic when using video conferencing apps that have two-way audio, but do work for standard type video and audio recording. Comica has not provided any details about compatibility for this wireless system with Zoom meetings and Apple is constantly making changes to the software. We cannot confirm compatibility as results can vary depending on the version of the phone and operating system. However, we can confirm that the Comica BoomX-D DMI2 does work for recording audio and video with audio on the iPhone.
