Deva Broadcast DB910 Full Duplex IP Audio Codec

IP Codecs
Deva Broadcast
De nieuwe Deva DB910 is een full duplex ip codec die tegelijkertijd audio kan verzenden en ontvangen voor een makkelijke conrole van het audiosignaal wat naar de zender wordt verstuurd.Als twee weg verzending niet nodig is kan deze codect uiteraard ook als losse encoder of decoder weken en zijn ze volledig compatable met de andere Deva broadcast IP codec modellen.

Deva Broadcast DB910 Full Duplex Compact IP Audio Codec

Inspired by DEVA continuous strive for excellence, and based on our long-term formative experience in the field 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 either as an encoder or 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 configurable 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 files 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.
