Williams AV had unveiled an updated version of its Digi-Wave 400 series digital intercom and tour guide communication system, featuring a new OLED display.
Two-way wireless communication is now enabled with the new Digi-Wave 400 system, allowing for communication between two devices at over 300 metres.
A new interface has been added alongside a new charging interface for the USB-C standard charging dock, with the Digi-Wave 400 system including at least one receiver (DLT 400) and can be combined with transceivers and receivers based on the application.
