Introduction
DSW (Digital Secure Wireless) is designed for no-compromise 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 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).
256-bit encryption is applied to the transmitted signal
stream for security against eavesdropping. The algorithm 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, microprocessor, 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 distributes 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.

Encryption key and settings transfer port
A cable between the transmitter and this port on the

Hardware Installation
Receiver Modules
The DR mainframe/host assembly is a wideband
design that coves the entire available frequency range.
Individual receiver modules are available in 25.6 MHz
frequency “blocks.” Any module can be installed in any
of the six mainframe positions without regard to the
frequency tuning range. Module positions correspond
to the rear panel audio outputs as shown here.

Installing Receiver Modules
1. Turn the mainframe power off.
The receiver modules interface with the main as-
sembly through multi-pin connectors on either side
of the chassis. Insert the module straight down and
then slide it toward the main housing to insert the
connector pins. The module should sit flush against
the side of the housing.

Antenna Connections
Connect the antennas or coaxial cables to the antenna
input connectors labeled IN on the rear panel.
Note: The frequency bandwidth of the antennas
must cover the range of the modules in use.
For multiple unit installations, a “loop thru” is available
to feed two or three receivers from a single antenna
pair. Connect coaxial cables from the multicoupler outputs on the first receiver to the antenna inputs on the
next receiver in the stack.

Retaining clip
Caution: Make sure the connectors align
correctly. Do not apply excessive force to seat
the module onto the tab.
2. Align the ridge on the retaining clip with the slot in
the chassis and press the clip downward until the
ridge snaps into the slot in the side panel.
Removing Receiver Modules
1. Turn the mainframe power off.
2. Remove the retaining clip by pressing the top side-
ways to release it from the slot in the side panel.
Then pull upward to remove it.
3. Pull outward on the module to release the connector and then lift it upward out of the chassis. Holes
in the underside of the chassis allow you to grip the
module on the top and bottom.

Audio Output Wiring - AES3 Digital
XLR output connectors deliver digital audio that conforms to the AES standard. The wiring is the same as
a balanced analog output.
Pin 1 Ground/Shield
Pin 2 Data (+)
Pin 3 Data (–)
Pins 2 and 3 carry the digital audio. Although polarity
is not an issue, it is good practice to maintain a “pin
to pin” connection - pin 1 to pin 1, pin 2 to pin 2, pin 3
to pin 3 in cables that terminate in XLR connectors at
both ends. It is best to use 110 ohm cable designed to
carry digital signals. Conventional microphone cables
may cause problems, especially with distances over 30
or 40 feet.
For pinout details of wiring to a DB-25 connector, refer
to the documentation for the device you are using.
Channel assignments per connector are marked on
the rear panel of the receiver.
Connections for Computer Interface
Connection to a computer for set up is easiest with a
