General Information

Compact, Robust, Reliable and Clever - This is just a small part of all the benets 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.
