Zaxcom Patents Technology Behind TRX Wireless Recording Systems

Zaxcom has received a U.S. patent for the company's virtual wireless multitrack recording systems.

Patent 7,711,443 covers the entire Zaxcom TRX family of digital wireless systems with built-in backup recording.

That includes tools like the TRX900LT digital wireless transmitter, first announced at the 2010 NAB Show, which can fully encrypt audio signals for secure transmission.

"Our TRX family of digital recording wireless systems provides television and film production teams with the unique ability to automatically and simultaneously record multiple tracks of digital audio while wirelessly transmitting the signals. The ability to perform all these functions in a single, compact, reliable system lessens equipment weight and cost while also safeguarding against the risk of lost audio," said Glenn Sanders, Zaxcom's president. "We're excited that this system has been recognized by the U.S. Patent Office as a significant and unique technology."

With the optional patented internal timecode-referenced audio recorder, each TRX system backs up all wireless transmissions on a removable microSD card to eliminate the possibility of audio loss due to interference or signal dropout.
