A leading feature of the DB4005 is the MPX input, which allows users to monitor external composite signals, regardless of whether they are from a composite STL receiver/stereo FM encoder, or from an off-air source. In addition, the loudness meter allows for measurements to be shown as defined by ITU BS.1770-4 and EBU R128 recommendations — the DB4005 supports both standards.

DB4005 is easy to use and packs a host of features. These include TCP/IP connectivity, audio streaming, and automatic alerts for operation outside of predefined ITU-R ranges, as well as optional GSM connectivity. Onboard tools include oscilloscope, loudness analyzer, spectrum analyzer, de-emphasis, stereo decoder, RDS/RBDS decoder, data logger, FTP server and audio streaming.

Alarms include RF, pilot left and right audio levels, MPX, MPX power and RDS. Remote operation can be rendered via PC or Android and Apple smart devices.
