General Information

DEVA’s DB8008 is a exible and reliable tool, designed by our engineers specically with

the aim of solving one of the most signicant problems in the radio industry – the one of radio

silence. DEVA’s smart and highly practical solution detects signal loss and immediately switches

the output to one of two alternative built-in backup players – MP3 or IP Audio. As an additional

advantage, it also allows for easy integration into the existing setups of a single station and large

radio networks alike.

The MP3 backup audio les and playlists can be uploaded to the device using any FTP client,

making this model not only ecient but also easy to use. The audio storage capacity of the unit is

an impressive 2GB for over 24 hours of audio playback without repetition. Moreover, the backup

sources priority is selected by users themselves.

The DB8008 features a fully DSP-based core, professional AES/EBU digital audio inputs and

outputs, and additionally allows for TCP/IP remote monitoring and control via SNMP and the WEB

Interface, which means that the device can also be used for local content or regional advertisement

spots. Another option provided by the model is the alert notications via email, SNMP or analog

opto-coupled outputs in case of signal loss.

Developed to provide users with a tool for an infallible and constant audio feed, the DB8008

is trademark DEVA device oering a simple and subtle solution to the problem of radio silence.
