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.

DR Receiver Front Panel
Front Panel Antenna Mounts
Convenient when the receiver is installed in a rack mount transit case.
Headphone Monitor
Monitor individual or a mix of any number of channels. Volume knob recesses into from panel.
LCD and Control Panel
Easy navigation of numerous setup parameters is pro­vided by a backlit LCD, membrane pushbuttons and a rotary control wheel.
DR Receiver Rear Panel
ANT PWR
AES 5 & 6
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
AES 3 & 4
AES 1 & 2

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.
