This Bundle Includes:
20 x Q-Audio QSD-3PRO Silent Disco Headset Receiver
1 x Q-Audio SD-CH20 Silent Disco 20-Way Charger
1 x Q-Audio QSD-3PRO TX+ Bluetooth Silent Disco Transmitter

This Q-Audio 20-Way Silent Disco Bundle with Bluetooth Transmitter and Charger is a complete wireless headphone system for silent disco events, schools, fitness classes, wellness sessions, guided tours, corporate activities, exhibitions, conferences and private parties. With 20 QSD-3PRO headset receivers, the QSD-3PRO TX+ Bluetooth transmitter and the SD-CH20 20-way charger included, this package is ideal for users who need a ready-made silent listening system for up to 20 participants.

The 20 included QSD-3PRO headset receivers are designed for direct-to-ear wireless audio, helping deliver clear music or speech without using loudspeakers. This makes the bundle useful in shared venues, noise-sensitive locations, schools, studios, outdoor sessions and multi-use event spaces where traditional amplified sound may not be suitable.

Each QSD-3PRO headset receiver offers 3 selectable channels within the CH70 band, operating between 863 and 865MHz. Built-in red, green and blue LED indicators show the active channel, making it easy for organisers to see which audio feed each user is listening to. Individual volume control on each headset lets every participant set their own listening level without changing the source volume for the whole group.

The QSD-3PRO TX+ transmitter gives the system a flexible and professional audio input point. Bluetooth pairing is included for quick wireless playback from compatible devices, while the balanced stereo XLR/combi jack inputs make it suitable for DJ mixers, controllers, sound desks, media players and AV systems. This makes the bundle suitable for both simple plug and play use and more professional event setups.

A 1/8 inch microphone input on the transmitter allows voice announcements to be mixed into the transmitted audio. This is useful for instructors, event hosts, teachers, tour guides, presenters and fitness leaders who need to speak over music or provide clear instructions to everyone wearing a headset.

The TX+ transmitter supports 3 selectable channels, with up to 3 transmitters able to be used together when extra audio feeds are required. This means the system can be expanded for multi-channel silent disco events, separate DJ channels, language options, guided tours or different listening zones. One TX+ transmitter is included in this bundle, giving one audio feed as supplied, with the option to add more transmitters later.

The SD-CH20 charger is designed to charge up to 20 QSD-3PRO headset receivers simultaneously, making it a perfect match for this 20-way bundle. It uses a high performance 5-way USB power supply with five 4-way USB-A to USB-C splitter cables, providing organised charging for the full headset set. Each headset charges via USB-C, with a full charge taking approximately 3 hours and providing around 8 to 10 hours of battery life.

Best for silent disco parties, wedding entertainment, schools, colleges, fitness instructors, wellness classes, guided tours, museums, conferences, exhibitions, corporate AV, venue entertainment, event organisers and hire companies needing a complete 20 headset silent disco system with Bluetooth transmitter and charging.
