Vonyx STWM712H - Dual VHF Wireless Headset Microphone System
The Vonyx STWM712H is a professional two-channel wireless microphone system operating in the VHF band, specifically designed to offer complete freedom of movement and crystal-clear voice transmission. This complete set eliminates the hassle of cables thanks to its two bodypack transmitters and corresponding headset microphones, allowing two users to operate simultaneously without mutual interference. It's the perfect solution for situations where hands-free operation is required, ensuring clear and powerful voice projection.
Signal reliability is at the heart of this system. Equipped with diversity antenna technology , the receiver constantly monitors signal quality and automatically selects the best reception to minimize dropouts, static, or dead spots on stage. The bodypack transmitters are lightweight, compact, and feature a belt clip that ensures a secure and discreet fit, allowing the user to move, gesture, or perform physical demonstrations without worrying about the equipment.
Integration with existing sound equipment is remarkably simple thanks to its professional connectivity options. The receiver features balanced XLR outputs and an unbalanced 6.3mm (Jack) mix output, facilitating connection to mixing consoles, amplifiers, or active PA systems. Furthermore, the front panel provides a clear view of system status via radio frequency (RF) and audio frequency (AF) LED indicators, ensuring that the technician or user has complete control over the equipment's performance at all times.
Main features
-
Dual VHF System: Allows the simultaneous use of two microphones on different fixed frequencies (200.175 MHz and 201.400 MHz) without signal crossing.
-
Diversity Technology: Dual antenna system that improves reception stability and drastically reduces signal interruptions.
-
Ergonomic transmitters: Lightweight bodypacks that operate on standard AA batteries, offering long autonomy and easy replacement.
-
Monitoring indicators: LED lights on the receiver to monitor RF signal and AF audio levels in real time.
-
Versatile connectivity: Audio outputs via 3-pin XLR connectors and 6.3mm jack for universal compatibility.
-
Antenna mounting: Antennas located on the front panel for easy installation in racks or confined spaces without obstructions.
Benefits for the user
The greatest benefit of the Vonyx STWM712H is its freedom of movement and control . Unlike handheld microphones, the included headset microphones maintain a constant distance from the mouth, ensuring consistent volume even if the speaker turns their head or moves vigorously. Setup is plug-and-play: by using fixed, highly stable quartz frequencies, there's no need to manually tune channels; simply turn it on and the system is ready to use. Furthermore, the energy efficiency of its transmitters guarantees hours of continuous use, reducing battery operating costs.
Use cases
-
Fitness instructors and gyms: Ideal for aerobics, spinning or yoga classes where the instructor needs to move intensely while giving instructions.
-
Presentations and conferences: Perfect for speakers who use their hands to point at slides or interact with objects.
-
Theater and performances: Allows actors to perform their roles without being limited by a handheld microphone or microphone stand.
-
Corporate and educational events: Excellent for teachers or trainers who need to move around the classroom or stage.
Frequently Asked Questions
Can both microphones be used at the same time?
Yes, the system is designed with two independent channels that operate on different frequencies, allowing both microphones to work simultaneously without interfering with each other.
What type of batteries do flasks use?
Each bodypack transmitter operates on 2 standard AA batteries (3V total), which are easy to obtain and replace.
What is the approximate range of the system?
While dependent on the environment and obstructions, VHF technology with diversity system typically offers a robust operating range suitable for standard scenarios, classrooms, and large conference rooms.
Project description
Dual VHF wireless microphone system with a desktop receiver and two bodypack transmitters with headset microphones. The system operates on the fixed frequencies of 200.175 MHz and 201.400 MHz with a frequency stability of 0.005%. The receiver incorporates diversity antenna technology for signal optimization, RF/AF LED indicators, and audio outputs via 3-pin XLR and 6.3mm combo jack connectors. Technical specifications include a dynamic range greater than 100dB, a frequency response of 40Hz to 20kHz, a signal-to-noise ratio >100dB, and THD <0.5%. The receiver is powered by a 12V adapter, and the transmitters by two AA batteries each.
