Q-Audio QSD-3PRO TX+ Silent Disco Transmitter

The Q-Audio QSD-3PRO TX+ is the updated transmitter for the QSD-3PRO system, designed to make setup faster and integration cleaner in professional environments. The key upgrade is balanced stereo XLR/Combi Jack inputs, making it far better suited to DJ mixers, controllers, and live sound outputs than RCA-style connections.

For quick control in the booth, the TX+ adds channel up/down buttons, dedicated Bluetooth power and pairing controls, and a clear LCD display showing essential status information such as battery and channel. A physical OFF/LO/HI switch lets you choose between lower power operation for shorter range and longer runtime, or high power for maximum coverage.

The TX+ supports both wireless and wired source workflows, includes a 1/8" microphone input for announcements mixed into the transmitted audio, and uses USB-C for power and charging, plus a separate USB-C service port intended for servicing/updates only. With UHF/FM transmission, stereo audio, and strong real-world range, it is built for silent disco events, tours, fitness classes, corporate AV, and multi-receiver listening environments.
