Q-Audio QSD-3PRO TX Silent Disco Bluetooth Transmitter, Channel 70

The Q-Audio QSD-3PRO TX Silent Disco Bluetooth Transmitter is a UHF transmitter purpose-built for seamless integration with the Q-Audio QSD-3PRO silent disco headphone system. Operating within the licence-free CH70 spectrum at 863–865 MHz, it delivers stable and interference-resistant RF transmission, ensuring clear and consistent audio delivery in a variety of event environments.

There is no limit to the number of QSD-3PRO headphones that can receive signal from a single QSD-3PRO TX transmitter, making it ideal for both small and large-scale deployments. For multi-channel playback, up to three transmitters may be used concurrently, each assigned to a separate channel (red, green, or blue). This enables simultaneous broadcasting of three distinct audio sources, giving users the freedom to choose their preferred content in real-time.

Designed with flexibility and scalability in mind, the QSD-3PRO TX is well-suited for silent discos, multi-language conferences, guided tours, and corporate events—any setting where high-quality wireless audio distribution is essential.
