The TS-681L is a Chairman unit of the TOA conference system, TS-680 Series of which compact and lightweight design makes it easy to install and store. Placing the talk key in ON position allows a chairman to speak and disable the speaker to prevent feedback. If the talk key is placed in the OFF position, the microphone cannot be used but the speaker is turned on, allowing voices from other conference units to be monitored. Priority key on the chairman unit allows chairman to take precedence over any delegate units. And the TS-681L Chairman Unit comes with a long microphone as a standard accessory.
