Lectrosonics DRM Encrypted Digital Wireless Receiver Module

Share

The Lectrosonics DRM Encrypted Digital Wireless Receiver Module is part of the DSW line (Digital Secure Wireless). Other DSW components include DB Digital Wireless Belt Pack Transmitter and the DR Digital Receiver.

The Digital Secure Wireless system, featuring AES-256-CTR (Advanced Encryption Standard) encryption technology, is ideal for use in environments where privacy is of paramount concern, such as corporate boardrooms, shareholder meetings, and government facilities. As a rugged and high-quality wireless microphone system, the new products will also find a home in theaters, film making, touring and other demanding applications.

AES (Advanced Encryption Standard) encryption technology employing a 256-bit key was approved as a government standard encryption algorithm in 2001 [FIPS 197]. The CTR (Counter) Encryption mode as found in the Lectrosonics Digital Secure Wireless system maintains low latency (2.5 ms overall) while keeping channel noise at a minimum. Key management is user selectable in one of two modes: "persistent", where the key is kept from session to session, and "one-time", where the key must be generated for each session (most secure). The system utilizes a special chip for entropy generation in order to ensure the key is generated in a truly random manner-thus complying with another government standard [FIPS 140-2]. The key transfer requires a simple cabled download, thus avoiding security issues with easily detected infrared key transfer systems.

The Lectrosonics DRM Digital Wireless Receiver Modules are individual receiver modules nested on both sides of the mainframe assembly. The modules tune across a 25.6 MHz range and can be positioned in any of the six pockets in the chassis. Delrin retaining clips keep the modules securely in place.

The modules are fan cooled for reliable operation when installed in racks with limited ventilation. Unused modules installed in the mainframe can be powered on and off with the software GUI or front panel controls. Please select frequency block when ordering.

CONSUMER ALERT: This particular wireless microphone device operates in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC's wireless microphone website or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
