Used in combination with the ST-300W-CT 7” Touch Controller, this HDMI synchronisation box mirrors the timer interface on any external display.
The unit receives data from the controller and outputs real-time speaker timing information - such as remaining time and status cues - on any monitor equipped with an HDMI input.
This functionality is particularly valuable for keeping the audience, stage managers, AV operators, and technical teams informed of speaking time without interrupting or distracting from the presentation.
Thanks to wireless connectivity or a wired RS485 network, the ST-300W-PB adapts seamlessly to both temporary event setups and permanent AV installations.
It is an ideal solution for large conference venues, auditoriums, technical control rooms, and backstage areas where extended visibility of speaker timing is essential.
