TOA TS-911 Chairman Unit for Conference System

The TOA TS-911 Chairman Unit is the flagship chairperson station in the TS-910 wired conference system lineup, designed to empower meeting leaders with full control, priority speech access, multilingual channel selection, built-in voting keys and seamless integration into corporate, government or international conference environments.

Featuring a compact, sturdy design, the TS-911 connects directly to the TS-919 Bridge Unit (for single- or multi-conference configurations) and uses the TS-910 Central Unit (via TS-918 Expansion) to support large scale assemblies. With a built-in loudspeaker, dual headphone jacks, priority speech key, voting buttons and recording output, this chairman unit offers both high functionality and professional presentation.

Perfect for boardrooms, council chambers, training rooms or multi-language convention halls, the TS-911 ensures the chairperson’s voice takes precedence, the meeting runs smoothly, and multilingual attendees stay engaged.
