Wireless Lavalier Microphone Comica BoomX-U U2 — Dual-channel UHF Bodypack System

Comica BoomX-U U2 is a wireless lavalier microphone system designed as a dual-channel UHF bodypack setup for capture of clear, hands-free audio in interviews, vlogging, presentations and field recording. The system consists of compact bodypack transmitters and a matching receiver that support clip-on lavalier microphones, enabling two independent audio sources to be recorded simultaneously without cables restricting movement. Its UHF operation and dual-channel configuration simplify multi-person recording and on-location workflows.

Advantages

The dual-channel design allows two separate lavalier microphones to transmit to a single receiver, reducing the need for multiple receivers in multi-person setups and streamlining monitoring and recording. UHF transmission offers stable wireless range and resistance to common interference in indoor and outdoor environments. Lightweight bodypack transmitters and clip-on lavalier microphones provide unobtrusive, hands-free operation for presenters and on-camera talent. The system is portable and intended to integrate with cameras, recorders, and mobile devices that accept an external microphone input.

Suitable for

• On-camera interviews and two-person conversations
• Vlogging and content creation where freedom of movement is required
• Presentations, lectures and corporate video recording
• Field recording and run-and-gun production

How to use

Attach the included lavalier microphones to the speakers' clothing and clip the bodypack transmitters securely to belts or pockets. Power on the transmitters and receiver, select matching UHF channels for each transmitter on the receiver, and confirm signal presence and levels on the receiver indicators. Connect the receiver output to your camera or recorder using the appropriate cable and adjust input levels to avoid clipping. Monitor audio through headphones if available and perform a quick sound check before recording to confirm clarity and channel separation.

Usage recommendations

Place the lavalier microphone element on the chest area, approximately 15–20 cm from the speaker's mouth, and conceal cabling to minimize rustle. Keep line of sight between transmitters and receiver when possible and avoid placing transmitters near large metal objects or strong radio-frequency sources to maintain optimal UHF reception.
