Introducing the Vox VDR™: Next-Generation Digital Radio System for Tour Guides
Elevate your guided tour experience with Vox VDR™, a state-of-the-art digital radio system that melds innovation, convenience, and exceptional audio quality into a single, elegant package.
Our next-generation technology is powered by patented intelligent pairing, ensuring an instant, seamless connection between the tour guide and participants. Even at whisper-level audio, the system delivers clear, high-standard quiet-vox-grade commentary. Designed for flexibility, Vox VDR™ offers up to 99 channels, allowing the guide to effortlessly select their transmission channel and get the tour started right away.
What sets the Vox VDR™ apart is its operation on the interference-free 1.9 GHz bandwidth, a fresh frequency band authorized by the ART. This allows the device to sidestep the congestion and interference commonly associated with the 2.4 GHz zone used by Bluetooth. Compliant with the latest European transmission regulations, our system promises an unbeatable, interference-free reception range of up to 300 metres, ensuring that you never miss a word.
In terms of durability and practicality, the Vox VDR™ excels with a staggering battery life of 65 hours and automatic on/off features. Its compact, lightweight, and stylish design makes it an ideal companion for any tour guide aiming to deliver a superior experience to their audience.
