Comica Audio BoomX-U QUA 4-Person Wireless Microphone

Designed for mobile journalists, videographers, and vloggers, the Comica BoomX-U QUA is a compact, true-wireless UHF microphone system with four mic/transmitters and just one receiver. It offers a complete solution for recording dialogue, interviews, and speech with four people talking simultaneously—directly to a mirrorless/DSLR camera or a mobile device.

The ultralightweight BoomX-U QUA consists of four 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 directly into your camera. Additionally, the included TRRS output cable gives you the option to plug the receiver into any smartphone equipped with a headphone jack.

The system operates in the UHF frequency band to deliver reliable transmission with clear sound at a line-of-site distance up to 394′. The built-in rechargeable batteries provide up to 6.5 hours of operation. Versatile and extremely easy to use with simple controls, the BoomX-U QUA is well suited for content creators of any experience level.

Four Microphones into One Receiver

The four-channel receiver allows you to save space on your shooting rig by using a single receiver to simultaneously receive signals from the four 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.

Built-In Mics for True Wireless

Each 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 high-pass filter switch, allowing you to eliminate unwanted low-end frequencies for clearer speech.
Furry windscreens are supplied to fit over the integrated mics on the transmitters to reduce wind and breath noise for more intelligible speech and dialog.

Lavalier Mics Included

For a more discreet setup, use the small lavalier microphones, which can be easily concealed away from the camera’s eye.
Foam windscreens are included with the lavs to reduce wind, breath, and plosive noise

Easy-to-Operate Wireless for 4 People

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.
The receiver’s crisp LCD shows signal strength, audio level, output configuration, and battery life.
Adjust the gain on each transmitter remotely from the receiver.
The receiver features two 3.5mm output jacks and a 3.5mm headphone jack for monitoring.
The system includes a 3.5mm TRS cable for your camera and a 3.5mm TRRS cable for your smartphone or mobile device; a 3.5mm to XLR cable is also supplied
You have the option to mix all four microphones together to a single dual-mono output or separate all of them and send the signals to the left and right channels on each of the receiver’s two 3.5mm outputs. If your camera or recording device offers two stereo inputs or four mono inputs, you can record each mic on an individual track, 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.

Monitor in Real 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.

UHF Wireless for Longer Distances

Whereas typical digital wireless systems are susceptible to interference from Wi-Fi devices, the BoomX-U QUA operates in the UHF spectrum, far away from the crowded 2.4 GHz band.
The system automatically scans the UHF spectrum to find an open frequency. For optimal performance, environments with minimal physical obstructions are recommended.
