DX121
The DX121 provides flexible wireless connectivity for Theatre, studio or OB environments, simply plugging into the headset connector of any popular intercom station, or connecting to a matrix intercom system via its four-wire interface. It enables wireless intercom links to be established quickly and easily, extending an operator's range by up to 300 metres.
An assignable relay closure offers further versatility, allowing the appropriate matrix channel to be selected from a belt pack. A single DX121 can support up to four HME remote Communicator Beltpacks or headsets, while the system's FHSS Spectrum Friendly technology offers partial-band selection, enabling up to eight DX121 wireless intercoms to be used simultaneously for multi-channel applications.
The unit can be used to support wireless channels for theatrical and live events crew, broadcast control room operators, tech support crews and for connecting remote staff at large venues, among other applications.
