General Information
The DB4402-V2 – Dual FM Monitoring Receiver is a superb and highly practical combination
between a logger and a streamer which allows you to easily and accurately monitor and store all
important parameters of the FM signal while simultaneously giving you the opportunity to listen to
a constant, uninterrupted audio stream. The synchronized performance of both major functions is
at the core of the idea for this model, as well as the unit’s major asset. You can listen to the selected
audio feed at the same time as the logger campaign is running. The design of this device relies
on simplicity coupled with functionality to offer customers the opportunity of a single solution to
both tasks.
Providing the stable, dependable operation characterizing all DEVA products, the DB4402-V2
is fully DSP-based, with a built-in oscilloscope and an RDS/RBDS decoder with a BER meter.
It also permits users to set alarms for RF, MPX, Pilot and RDS signal via email, SMS or SNMP.
What is more, the TCP/IP and GSM connectivity provides easy remote control, monitoring and
listening to the radio signal from any location.
The device offers a “Restore Factory Defaults” option and easy update of the rmware. It is
an advanced solution giving customers a number of advantages and top all-round, multi-faceted
performance as both a monitoring tool and a streaming device.
