Description

Q Audio 20 Way Silent Disco Bundle With 20 x Headsets, Portable Transmitter & Charger.

The Q-Audio Silent Disco 20-Way BTX System is a portable, Bluetooth-enabled wireless audio package designed for small to mid-sized events. Featuring 20 QSD-3PRO headsets, one QSD-3PRO BTX battery-powered transmitter, and one SD-CH20 charging station, this setup offers high-quality sound, flexible operation, and complete freedom from mains power.

Compact and Wireless Operation

Powered by an internal rechargeable battery, the QSD-3PRO BTX transmitter delivers interference-free UHF audio on the licence-free CH70 spectrum (863–865 MHz). Perfect for outdoor events, guided tours, fitness sessions, or small silent discos, it provides the same professional sound performance as larger systems—without the need for cables or a fixed power source.

Bluetooth and Line Input Connectivity

Connect any Bluetooth device directly to the transmitter or use the included RCA and 3.5 mm cables for a wired connection to mixers or laptops. The transmitter supports three channels (Red, Green, Blue), allowing up to three BTX units to run simultaneously for multi-channel audio playback.

Comfortable and Reliable Headsets

Each QSD-3PRO headset features soft padded ear cushions, adjustable volume control, and coloured LED indicators to show the active channel. With up to 10 hours of battery life and a 3-hour charge time, they’re built for long sessions and consistent performance.

Efficient 20-Way Charging Solution

The SD-CH20 charging station includes a 5-way USB power hub and five 4-way splitter cables, giving you 20 USB-C outputs for simultaneous charging. Compact and organised, it’s ideal for event setups and transport.
