DSW Digital Wireless System

Rio Rancho, NM

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.
