Descriptions Lectrosonics DR, Digital Encrypted Wireless System DR - Encrypted Receiver The Lectrosonics DR is a completely new digital architecture was developed for the DSW wireless system. Extended operating range rivals the best analog and Digital Hybrid Wireless® systems, with remarkable audio quality and only 2.5 ms of latency. The system operates on standard UHF FCC Part 74 frequencies (TV channel band). The Lectrosonics DR receiver is a modular, six-channel design with a host mainframe that contains the DSP, microprocessor, antenna multicoupler and control interface. Receiver modules are installed on either side of the mainframe. Antenna ports on the rear panel of the Lectrosonics DR accept input from remote antennas, with a “loop-thru” output to another mainframe using the internal multicoupler. A kit is also available to mount antenna inputs (BNC connectors) on the front panel, with a coaxial cable routed inside the mainframe chassis to a rear panel location.
