loop-thru for additional receivers
• 256-bit encryption - AES 256-CTR
• Transmitter tunes entire frequency range
• Extended operating range
• Analog and AES-EBU audio outputs
• Ethernet interface
• USB interface
• RS-232 serial interface
• Includes PC software for Windows/Mac
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 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 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.
The DBa 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.

Antenna Ports
Antenna inputs and outputs to an additional mainframe
allow “stacking” of up to three mainframes with a single
pair of antennas.
Audio Outputs
Six XLR jacks provide analog and AES-EBU outputs in
various configurations as labeled on the rear panel.
Ethernet Port
Network connection is provided through a standard RJ45 jack.
Encryption Key Interface
Encryption key transfer and complete transmitter setup is
accessed through a TRS mini-jack connection.
Front Panel USB Port
A standard USB interface is provided on the front panel
for the PC interface.

AES Word Clock
The mainframe can provide the master clock sync signal,
or sync to an external clock.
RS-232 Port
Control with third party devices is enabled through an
RS-232 serial port.
Power Supply
The mainframe is powered by 10 to 18 VDC from an
external 4 amp source.
Modular Versatility
Individual receiver modules are 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 or
front panel controls.
DBa Belt Pack Transmitter
The belt pack transmitter is
constructed of solid machined
aluminum for lasting ruggedness. The exterior is finished
with an ultra hard, black
electroless nickel finish called
ebENi.
Setup and adjustment is enabled through a backlit LCD,
membrane switches and an
intuitive menu structure. Input
gain is adjustable over a wide
range in 1 dB steps to optimize modulation and limiting.
The servo bias input preamp
adapts to any microphone or
line level input with simple connector wiring.
A separate switch is provided
on the top panel that can be
configured as a mute or power
switch, or be bypassed.
Firmware updates are made
through a side panel mini-USB
port.
Top panel input jack, mute/power switch and
antenna connection.
Battery compartment uses two AA batteries
connected in series. Aluminum door latches
securely.
Wireless Designer Software
The software GUI provides an overall view of the system,
including all mainframes connected. The display is scalable to fit and screen size and several color themes are
provided.
System overview with scan results
Frequency coordination is fast and thorough. Scan data
may be imported and used in the coordination. When
individual carriers are moved manually, compatibility is
instantly recalculated and displayed.
