DSW Digital Wireless System

Introduction

DSW (Digital Secure Wireless) is designed for no-com-
promise applications where performance and security
are the highest priority.
A completely new digital architecture was developed
for the DSW wireless system. Extended operating
range rivals the best analog and Digital Hybrid Wire-
less 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).
256-bit encryption is applied to the transmitted signal
stream for security against eavesdropping. The algo-
rithm conforms to the AES 256-CTR standard.
DR Modular Receiver
The DR receiver is a 1RU modular, six-channel design
with a host mainframe that contains the DSP, micro-
processor, antenna multicoupler and control interface.
Receiver modules are installed on either side of the
mainframe. No tools are required to remove and install
the receiver modules. Each module will tune across a
25.6 MHz range.
Antenna ports on the rear panel accept input from
remote antennas, with a "loop-thru" output to another
mainframe. A high quality internal multicoupler distrib-
utes the RF signal to the receiver modules.
For rack mount installations, a kit is available to mount
antenna inputs (BNC connectors) on the receiver front
panel using a coaxial cable routed through the receiver
chassis to the rear panel connections.
DB Belt Pack Transmitter
The DB belt pack transmitter is encased in a solid
machined aluminum housing with a membrane switch
panel and backlit LCD interface. The servo bias input
circuitry will work with a wide variety of microphones
and line level sources, Input gain is adjustable over
a wide range in 1 dB steps to optimize the signal to
noise ratio and dynamics of the audio.
The transmitter tunes across the entire frequency
range of the DSW system, from 470 MHz to 691 MHz.
