Buzzer System
Be it game or show, studio or stage - the buzzer system is a great thing. The system identifies the first of two up to four players to press his/ her button. Once a button is pressed, the console emits a preselectable sound and a light signal on top of the console identifies the first player. The light stays on until the reset button in the software is pressed.
The system comes with a central electronic unit (powered from a wall outlet, no batteries) plus a console for each candidate. The system can be shipped safely because of the rugged flight cases.
