Zaxcom Provides Secure Audio Transmission Encryption

  • Zaxcom's new TRX900LT digital wireless transmitter, first announced at the 2010 NAB Show, features the ability to fully encrypt audio signals for secure audio transmission in corporate and legal settings where sensitive material may need to be protected from signal interception or theft. The TRX900LT bodypack unit combines wireless transmission, recording, and remote control receiving functions into a single low-cost wireless transmitter.
  • To activate the encryption, a TRX900LT user simply enters an encryption code into the transmitting and receiving units. With over 16 million key code combinations, it's impossible to decode the audio signals without the key. Once the code is entered, the system will encrypt all signals automatically.
  • "There are many situations in corporate offices, religious facilities, and legal settings in which sensitive material may need to be protected during transmission and recording. As with all of our digital wireless technologies, our new TRX900LT addresses this need with complete digital audio encryption. In addition, the TRX900LT packages a powerful feature set into our lightest, lowest-cost unit that fits well with virtually any setting and budget," said Glenn Sanders, Zaxcom's president.
  • Like all technologies in Zaxcom's popular TRX product line, the TRX900LT bodypack unit features 100 percent digital transmission for audio quality that rivals a hard-wired system, and it is superior to all analog and hybrid wireless units. Designed to be extremely lightweight and durable, the TRX900LT is housed in a high-strength, impact-resistant nylon polymer casing that provides protection from both corrosion and water damage.
  • With a patented internal timecode-referenced audio recorder that backs up all wireless transmissions on a removable microSD card, the TRX900LT eliminates the possibility of audio loss due to interference or signal dropout. By integrating a group of TRX900LT units, users in board meetings or other company events are able to establish a multi-track recording session directly from the bodypack units. Each TRX900LT unit will operate for up to five hours on a single AA lithium battery and is compatible with all Zaxcom wireless receivers and IFB transmitters.
  • Also included in the TRX900LT transmitter is reception of remote controls via ZaxNet. ZaxNet is Zaxcom's new 2.4-GHz RF network that enables distribution of remote control signals, timecode, and metadata. With ZaxNet, TRX900LT users will be able to control gain and audio replays remotely via a timecode reference so that multiple Zaxcom wireless systems can replay audio in sync. The TRX900LT-ZaxNet integration also will allow users to remix audio from multiple transmitters, creating a virtual multitrack playback and re-record system.
