Eartec TD 904 Pro Overview

The Eartec TD 904 Pro Series is a portable, four-station wireless intercom system operating in the UHF frequency range. The full-duplex system consists of four TD900 radios (one master, three remotes) and four ProLine single-sided headsets equipped with adjustable, noise-cancelling, electret microphones. The system is powered by rechargeable NiCad batteries.

The TD 900 is truly portable and operates independently of any fixed remote base stations, supporting a virtually unlimited number of remote expansion units. There is a generous allocation of accessible, top-loaded controls and indicator lights, expressed on a very compact and lightweight frame. The TD 900 comes with an attached belt clip.

The ProLine headset is a popular "pro-audio" headset that is widely used in the television and video production industries. You can wear the ProLine in comfort for hours, thanks to the wide, cushioned headband and deluxe foam ear cushion. The flexible steel mic boom allows you to precisely position the electret condenser microphone.
