The Eartec TD 900R is a full duplexing, truly portable UHF remote wireless transceiver, designed as an expansion solution for the Eartec TD 902 wireless intercom system. While a virtually unlimited number of expansion units may be used, the operating design allows for only one speaker at a time. All remotes monitor the director, and when called upon, may switch from Standby (listen only) to continuous talk operation.
There is a generous allocation of accessible, top-loaded transceiver controls and indicator lights, expressed on a very compact and lightweight frame, and the unit comes with a rugged integral belt clip.
The TD 900R is a viable, and very affordable, wireless communication expansion solution for the budget-minded professional ENG, Event, and House of Worship video crew.

Comments about Eartec TTD-900R - Full Duplexing Wireless Remote Transceiver - Remote Only:
I use it in an event for cars .. like a carshow. Works great with no noice or other fuzz. Easy to set up and handle. The volyme could have ben a little louder. We have it on maximum volume in our headsets and that´s just about enough
