The TOA TS-780 Central Unit is a powerful and versatile component for the TOA Conference System, designed to handle multiple conference units while maintaining high-quality audio and seamless communication. It features line connection terminals that allow easy connections to the TS-781 and TS-782 conference units, enabling the creation of a flexible and expandable conference system. With the capability to connect up to 3 central units, the TS-780 can be expanded to meet the needs of larger conference setups.

One of the standout features of the TS-780 is its MP3 recorder, which allows conference contents to be recorded directly to an SD card for later playback or documentation. This feature ensures that important discussions are captured and can be easily reviewed. The unit also offers a variety of control functions, such as a priority speech chime, speaker restriction (up to 4 delegate units), and an automatic microphone-off function, which can be set to activate after 30 seconds.

The TS-780 also includes a feedback suppressor (FBS), with selectable EXT, OFF, AUTO, and MANUAL modes, providing optimal sound quality and minimizing unwanted audio feedback during the conference. The unit features both input and output terminals for various connections, including a recording output for external devices and headphone output for private listening.

For flexible installation, the TS-780 can be mounted in an EIA Standard equipment rack using the optional rack mounting bracket (MB-23B), making it a space-efficient solution for conference room setups. It is powered by a 220–240V AC supply, and its sturdy construction with an aluminum panel and steel case ensures durability in professional environments.
