USB buzzers

This buzzer has an XLR connection. You can therefore deport it up to 50 m thanks to simple microphone cables. The feet of his hull have a spacing of 8 cm, which allows him to insert directly into the top of a beam F14.

HF Buzzers

Same design as USB, our HF buzzer uses 433 MHz radio technology. It can operate on battery with a minimum autonomy of 12 H. With its USB receiver (a receiver can handle 50 HF buzzers), its range is greater than 500 m.


Software side, this buzzer does not need a driver. It is seen as a standard communication port of the system (Windows, Linux, Mac). Directly compatible with our BQuizz system, it can also simulate the keys of a keyboard thanks to the utility “BuzzKeys” (Windows 10 only) which makes it compatible with most software of quiz of the market.


Make the choice of tailor-made! for the same price, choose the color of your button as well as that of your shell when ordering (button: green, white, red, blue, yellow, shell: black, red, blue, green, orange).
