This Bundle Includes:
100 x Q-Audio QSD-3PRO Silent Disco Headset Receiver
2 x Q-Audio SD-CH48 Silent Disco 48-Way Charger
1 x Q-Audio QSD-3PRO TX+ Bluetooth Silent Disco Transmitter

This Q-Audio 100-Way Silent Disco Bundle with Bluetooth Transmitter and Chargers is a large silent listening package for event organisers, venues, schools, universities, fitness operators, corporate AV teams and hire companies needing a professional wireless headphone system for bigger audiences. With 100 QSD-3PRO headset receivers, 2 x SD-CH48 high capacity chargers and 1 x QSD-3PRO TX+ Bluetooth transmitter included, this bundle is designed for silent discos, guided listening events, classes, tours, conferences and large group activities.

The 100 included QSD-3PRO headset receivers deliver audio directly to each listener without the need for loudspeakers. This makes the system especially useful for noise-sensitive venues, shared event spaces, hotels, schools, gyms, outdoor sessions, museums, exhibitions and late-night entertainment where clear sound is required without creating high external noise levels.

Each QSD-3PRO headset receiver features 3 selectable channels within the CH70 band, operating between 863 and 865MHz. Integrated red, green and blue LED indicators show the active channel selected on each headset, making it easier for organisers to manage groups and identify which users are listening to each feed. Individual volume control on each headset allows every listener to set their own comfortable level without changing the source volume for everyone else.

The QSD-3PRO TX+ transmitter gives the bundle a flexible audio input point for music, speech and event audio. Bluetooth pairing allows quick wireless playback from compatible devices, while the balanced stereo XLR/combi jack inputs are suitable for DJ mixers, controllers, live sound desks, media players and professional AV systems. This makes the bundle practical for both simple music playback and more demanding event setups.

A 1/8 inch microphone input on the transmitter allows announcements to be mixed into the transmitted audio. This is useful for event hosts, fitness instructors, tour guides, teachers, presenters and activity leaders who need to speak over the programme material and communicate clearly with everyone wearing a headset.

The QSD-3PRO system supports 3 selectable channels, with up to 3 compatible transmitters able to be used together when additional audio feeds are required. This bundle includes one TX+ transmitter, giving one audio feed as supplied, with the option to expand later by adding more transmitters for multi-channel silent disco events, multiple DJs, language options or separate listening zones.

The two included SD-CH48 charging systems provide high capacity USB-C charging for QSD-3PRO headset receivers. Each charger can charge up to 48 compatible headphones at once, giving a total simultaneous charging capacity of up to 96 headsets across the two chargers. The remaining 4 headsets can be charged separately or in a second charging cycle, making the charging setup practical for preparing a large 100-headset system before events.

Each QSD-3PRO headset charges via USB-C, with a full charge taking approximately 3 hours and battery life of around 8 to 10 hours. This makes the bundle suitable for extended events, repeated classes, corporate sessions, event hire and professional use where a large number of headsets need to be kept charged, organised and ready.

Best for silent disco parties, wedding entertainment, universities, schools, fitness events, wellness classes, guided tours, museums, conferences, exhibitions, corporate AV, event hire, festivals, venues and organisers needing a large 100-headset silent disco system with Bluetooth transmitter and high capacity charging.
