At NAB 2006, Zaxcom introduced its new TRX900 and TRX990 digital wireless microphone transceivers. The TRX900 system is designed for use with a lavalier microphone, while the TRX990 is engineered as a complete solution to boom pole–type transmitters and offers two audio channels with integrated phantom power. These systems record directly to a Flash memory card, storing audio as WAV files that can be transferred to a PC or Mac.
Optional timecode transmission and video sync generation allow the user to transmit two channels of audio, timecode and video sync to just one receiver on the camera. Video sync types include tri-level, NTSC and PAL. A built-in IFB receiver allows the user to receive cues and other information from the production staff without an additional bodypack. The RF remote-control feature allows users to change the parameters of a microphone—such as mic gain, highpass filter or the selected channel—from up to 200 feet away.
Zaxcom’s TRX900AA operates for up to 12 hours on two AA batteries and provides integrated recording of up to 12 hours of audio.
