Introduction
DEVA Broadcast Ltd. was established in 1997 as a broadcasting and telecommunications
equipment importer for Bulgaria and Eastern Europe regions. Subsequently, DEVABroadcast Ltd.
hasdeveloped andproduced awiderange oflow and midpower transmitters,RDS/RBDS Encoders
and Decoders, Modulation Monitors, Remote Controls, Site monitoring and other systems for
many companies. Our high degree engineers accomplish their bright ideas through successful
engineering, marketing and management in DEVA Broadcast Ltd.’s Headquarter in Bulgaria.
During the last ten years the company products have become our partners’ best sellers. After
detailed marketing analysis, our team has decided to launch its own brand products based on the
latest technologies in the broadcasting business. The company’s main goal is to design, develop
and offer a complete line of high quality and competitive products for FM and Digital Radio,
Radio Networks, Telecommunication Operators and regulation authorities. We base our market
authority position on our good after sales support and relation with the clients.
Since 2003 DEVA Broadcast Ltd. has been ISO 9001 certied .
The contractors of DEVA Broadcast Ltd. are satised with the permanent business comfort
and to their own confession they owe it to a great extent as well as their prosperity to the loyal

General Information
Compact, Robust, Reliable and Clever - This is just a small part of all the benets of our DB44
FM Radio Monitoring Receiver and Basic Modulation Analyzer. Based on the latest technology,
the DB44 core is DSP based digital design for 24/7/365 operation.
After demodulating the FM signal, the MPX signal is digitalized and all signal processing
is then made through calculations. Digitizing in this way, at the input gives the equipment
measurement reproducibility over time. Digital lters’ accuracy, used in this equipment, enables
the FM multiplex signal’s components to be accurately and repeatedly reproduced from one device
to another, i.e. same signal applied to two devices will give the same result. The processing power
in this equipment enables all measurements to be refreshed simultaneously and synchronously,
thereby allowing for detailed readings of all the Multiplex FM signal components.
DB44 allows you through its TCP/IP and GSM Connectivity to monitor all the RDS and some
other signal parameters from anywhere. You can easily receive the channel status or listen to the
audio from anywhere, using your mobile phone. With the built-in Audio Streamer you can even
listen to, skim and record the audio from any station. DB44 is our most cost effective unit for
permanent monitoring of the quality and continuity FM Radio Stations or Radio Networks.
