Vonyx STWM712 - Dual VHF Wireless Microphone System with Diversity Technology
Forget the limitations of cables and experience true freedom of movement with the Vonyx STWM712 wireless microphone system. This professional two-channel set operates in the VHF band, offering a robust and affordable solution for those seeking high-quality audio without technical complications. Designed for reliable performance in a wide variety of environments, the STWM712 stands out for its engineering focused on signal stability and vocal clarity.
The heart of this system is its diversity receiver. Unlike standard single-antenna systems, the STWM712 employs two front-mounted antennas that work together to constantly monitor signal quality. If one antenna detects a drop in signal or interference, the system instantly compensates, ensuring that the audio remains continuous and clear. This feature is crucial for preventing dreaded sound dropouts when users move around the stage or room.
The kit includes two ergonomic handheld microphones , each tuned to a different fixed frequency (200.175 MHz and 201.400 MHz), allowing two people to speak or sing simultaneously without interfering with each other. Thanks to its excellent signal-to-noise ratio of over 100dB and a wide frequency response, voice reproduction is natural, clear, and full of presence, making this system a versatile tool for both spoken word and live singing.

Benefits for the user
The Vonyx STWM712 is designed to simplify the user's life. Its setup is virtually "plug and play": with factory-set frequencies, you don't need to waste time scanning channels or syncing devices; simply turn it on and use it. The lightweight construction of the handheld microphones reduces fatigue during long performances, while the compact receiver takes up minimal space on your work surface or DJ setup. Furthermore, the flexibility of its audio outputs allows you to integrate it into everything from home karaoke systems to more complex PA systems.
Ideal use cases
-
Events and Presentations: Ideal for speakers, lecturers or masters of ceremonies who need to move freely around the stage.
-
Karaoke and Vocalists: Perfect for duos and amateur singers who require a clear voice without distortion.
-

Animation and DJ: An essential tool for DJs who make announcements or liven up parties, allowing them to interact with the audience away from the booth.
Frequently Asked Questions
Can I use both microphones at the same time?
Yes, absolutely. Each microphone is calibrated to a specific and distinct frequency, so both can operate simultaneously without causing mutual interference.
What is the scope of the system?
Although it depends on the environment and physical obstacles, the system offers a wide and sufficient operating range for most scenarios, event halls and medium-sized auditoriums, maintaining stability thanks to its diversity antennas.
How do I connect it to my sound system?
The receiver offers complete versatility. You can use the Mix Out (6.3mm jack) to send both voices mixed to a single input on your speaker or amplifier, or use the XLR outputs to send each microphone to a separate channel on a mixing console for more precise control.
