Wireless Mic System from Lectrosonics Utilizes 256-bit Encryption

Letrosonics’ new wireless mic system provides the latest encryption technologies, while maintaining low levels of latency.

The Rio Rancho, N.M.-based company Lectrosonics produces a variety of professional audio products that address a variety of applications.

The Skinny: The latest product announcement from this Southwestern-based company provides users who are concerned with the security level of wireless audio solutions a reason to invest in wireless transmission systems.

The Specs: Lectrosonics’ newly announced Digital Secure Wireless system utilizes AES-256-CTR (Advanced Encryption Standard) encryption technologies, and a choice of “persistent” and “one-time” user modes that offer users the ability keep security keys from session to session or to engage new keys for each new usage session.

“The new Digital Secure Wireless system is the ideal tool for those environments where privacy is crucial and is, for example, particularly well suited for use at large corporations, banks and other financial institutions,” says Karl Winkler, Director of Business Development, Lectrosonics. “With the passage in 2002 of the Sarbanes-Oxley Act, information security and access control have been central themes with companies in compliance with the law. Closed sets, theater and live productions can similarly benefit from secure wireless mic transmission.”

Lectrosonics says the system maintains low latency levels (as low as 2.5ms), and that it includes a DR digital wireless receiver frame, individual DRM digital receiver modules and DB digital wireless beltpack transmitters. The company says the DR digital wireless receiver frame supports as many as six channels/modules in 1RU, and it includes analog and digital (AES/EBU) XLR outputs that are selectable from a device menu.

Lectronics adds that the frame supports wideband reception (470.100 to 691.175MHz), and it includes other features such as 50-ohm BNC antenna inputs and outputs for cascading up to three additional frames for a total of 24 channels.

In addition, the company points out that each receiver module docks into the DR digital wireless receiver frame and up to six modules can be docked per DR frame. Each module has 25.5MHz of bandwidth. The beltpacks offer wideband tuning (470-698MHz), as well as a linear RF output stage for reduced intermodulation distortion.

Solutions: The Digital Secure Wireless system from Lectrosonics can be used for corporate sound installations, and live music and theater installs.
