Zaxcom Dramatically Extends IFB Audio Range, Flexibility With New Voting Feature

(September 07, 2007)
DMN Newswire--2007-9-7-- Zaxcom, a pioneering provider of professional audio equipment for the television and film industries, today announced a new IFB voting feature for the companys TRX900 family of digital wireless microphone transceivers. The voting feature, part of the new 2.4-GHz IFB100 on display at IBC2007, allows the TRX900s internal IFB receiver to select the highest quality signal automatically from a group of IFB transmitters operating on different frequencies. With this capability, users can greatly extend the range and flexibility of their wireless microphone systems by setting up several IFB transmitters within a large space.

?Weve expanded on our new IFB100 to include a voting feature, which will further open the doorway for the use of wireless microphone transceivers, even in the difficult or expansive environments often encountered in reality TV or live news productions. Audio crews could set up IFB transmitters on each floor of a building, for example, and be confident that together the transmitters will provide an extended coverage area free of any RF interference from the walls of the building, said Glenn Sanders, president of Zaxcom. ?In much the same way as a mobile phone switches among cellular towers to provide the caller with the best signal, our IFB voting feature allows the TRX900 to seamlessly and invisibly select the strongest signal at any given time.


Zaxcoms IFB100 operates at 2.4 GHz and uses spread-spectrum technology for superior resistance to interference. Up to 32 IFB channels can be operated at one time. The IFB100 with integrated voting is designed for use with Zaxcoms TRX900 and TRX900AA digital wireless microphone transceivers, the industry's first wireless microphones with internal IFB, integrated audio recording, and timecode transmission. This patent-pending feature set allows audio professionals to record up to 12 hours of audio directly to a Flash memory card and then transfer the .wav files to either a PC or Macintosh for post-production.

More information about this product and Zaxcoms full line of wireless audio systems is available at or at IBC2007 in the Ambient Technologies stand, 8.481, Sept. 7 11, 2007, in Amsterdam.
