Features:
The TS-772 is a Delegate unit for TOA Conference system, of which compact and lightweight design makes it easy to install

the speech button is placed in the OFF position, the microphone cannot be used but the speaker is turned on, allowing the

as optional products: the TS-773 standard type and the TS-774 long type.
