• Six-channel modular design

• Built-in wideband antenna multicoupler with

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

sys-

tems, 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, microproces-

sor, 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 ma-

chined 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.

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.
