General Information

The best device to ght the dreaded dead air problem is the DB8008 from DEVA Broadcast Ltd.

It is designed and built to be simple, exible, reliable and easy for integration with the existing

setups of any single station to a large radio networks. The basic principle of DB8008 is that this

unit can detect the silence and switch the output to some of the alternative sources.

The MP3 backup audio les and play lists can be uploaded in the DB8008 from your PC using

any FTP client. The audio storage capacity of DB8008 is 2 Giga Bytes.

The DB8008 provides additional security in case of loss of audio at the inputs. The audio

backup is presented as an integrated auxiliary audio input for external program’s backup audio

source, IP Stream and built-in MP3 audio player.

The unit has SNMP and WEB remote control features. Through this feature the DB8008 can be

used for local content or regional advertisement spots insertion.
