The TOA TS-781 Chairman Unit is a high-quality conference system component designed specifically for chairpersons, offering complete control during meetings and discussions. With its built-in priority function, the chairman can override all delegate units, ensuring smooth communication and organized discussions.
When the SPEECH button is pressed, the chairman’s microphone activates, and the built-in speaker automatically turns off to prevent acoustic feedback. When the button is released, the microphone deactivates and the speaker turns back on, allowing the chairman to listen to other participants clearly.
The unit includes a headphone/recording output for private listening or external recording and supports both TOA TS-773 (standard microphone) and TOA TS-774 (long microphone) options for flexible configurations.
