General Information

Inspired by DEVA continuous strive for excellence, and based on our long-term formative

experience in the eld of IP audio broadcasting tools, DEVA product portfolio is extended with yet

another strategic solution - the DB910 Full Duplex IP Audio Codec.

A full duplex solution when two tools are in use, the DB910 allows you to send and receive

audio at the same time, while guaranteeing fast and easy monitoring of the signal fed to the

transmitter. Where two-way transmission is not required, DB910 may be used as a decoder, being

fully compatible with DEVA’s already widely-known hallmark IP audio codecs.

The real time audio encoding/decoding into a high quality congurable format process is

uncompromisingly guaranteed by the powerful DSP processor. Supporting all the mandatory

compressed audio streams and lossless, uncompressed PCM stream, the DB910 can be used for

a wide range of professional audio applications: Broadcast, Internet Radio, Studio to Transmitter

Link and VoIP.

Apart from its main audio source, DB910 supports several IP audio sources and a built-in MP3

Backup Audio Player in addition. With several backup audio sources incorporated, the DB910 will

immediately switch between the sources when the audio is lost, and return to the main one when

the audio is restored, with no user intervention. The audio content for the MP3 player is recorded

on the internal SD card. The backup les can be managed remotely through the built-in FTP

Server, via standard FTP client.

Combining the super compact form of the DB90 and some of the most impressive features of

the renowned DB9000 line in a single product, the DB910 will meet the requirements of the most

demanding broadcasters. This advanced radio gear is equipped with two-way GPIOs and RS-232

serial communication that could be used for telemetry and automation. The front panel audio level

bar graphs and LED indicators of the unit allow reading the current state of the device at a glance.

Controlled through a simple and intuitive HTML5 interface and any kind of web browser, be it

your PC, smart phone or tablet, the DB910 could be managed remotely or locally.

DB910 is the ultimate all-in-one solution to maintain your competitiveness, combining essential

professional applications and key trends.
