The Q-Audio QSD-3PRO TX+ is an updated silent disco transmitter designed for professional wireless headphone systems where simple setup, clean audio connection and reliable coverage are essential. Built for the QSD-3PRO silent disco range, it is ideal for silent disco events, weddings, festivals, schools, fitness classes, wellness sessions, guided tours, corporate AV and multi-channel listening environments.

A key upgrade on the TX+ is the addition of balanced stereo XLR combi jack inputs, making it easier to connect directly from DJ mixers, audio interfaces, live sound desks, media players and professional AV equipment. This gives event users a cleaner and more flexible input option than basic consumer style connections, especially when the transmitter is being used in a live or commercial setup.

For fast operation, the QSD-3PRO TX+ includes channel up and down buttons, a clear LCD display and dedicated Bluetooth power, pairing and unpair controls. Bluetooth connectivity allows convenient wireless audio playback from compatible devices, while the wired inputs remain available for professional source equipment when a direct audio feed is preferred.

The transmitter operates with 3 selectable channels within the CH70 band, allowing up to 3 transmitters to be used together with one channel selected per receiver. There is no fixed limit to the number of compatible QSD-3PRO receivers that can be used on each transmitter, making it suitable for building silent disco systems for small private groups through to larger event audiences.

A useful 1/8 inch microphone input allows voice announcements to be mixed into the transmitted audio, making the TX+ practical for instructors, event hosts, tour guides, teachers and presenters as well as DJs. This makes it especially useful beyond traditional silent disco, including fitness instruction, guided wellness sessions, museum tours, school activities, conferences and outdoor classes.

The physical OFF, LO and HI switch lets users choose the transmit power level to suit the venue and battery needs. Low power mode is useful for shorter range situations and longer runtime, while high power mode provides maximum coverage with an effective range of up to 300m in suitable conditions. The unit also includes BT and RF antenna connections to support stable wireless performance.

Power and charging are handled through USB-C, while a separate USB-C service port is provided for servicing or updates only. Compact, practical and designed for modern silent disco systems, the Q-Audio QSD-3PRO TX+ is a strong choice for anyone expanding or upgrading a QSD silent disco setup with professional audio inputs, Bluetooth convenience and flexible channel control.

Best for silent disco events, weddings, parties, festivals, schools, fitness instructors, wellness classes, guided tours, museums, conferences, corporate AV, venue entertainment and hire companies needing a reliable QSD-3PRO compatible transmitter.
