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.

LED Indicators

Operational and power status is indicated by three LEDs.

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.
