DEVA Broadcast DB4402-V2 – Dual FM Monitoring Receiver & Radio Streamer

Logger capability and simultaneous audio streaming in one innovative tool

The DEVA Broadcast DB4402-V2 – Dual FM Monitoring Receiver – is a superb and highly practical combination between a logger and a streamer. It allows you to easily and accurately monitor and store all important parameters of the FM signal. It simultaneously gives you the opportunity to listen to a constant and uninterrupted audio stream.

The synchronized performance of both major functions is the core of the idea for this model. It is 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. It offers customers the opportunity of a single solution to both tasks.

Providing the stable, dependable operation characterizing all DEVA products, the DEVA Broadcast 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 signals 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 firmware. It is an advanced solution giving customers a number of advantages and top all-around, multi-faceted performance as both a monitoring tool and a streaming device.
