DB9000-RX – IP Decoder

This is a device designed to support HE-AAC and MPEG-1 Layer 3 compressed audio streams and PCM uncompressed stream for audio transmission without quality loss. Decoding takes place in real time by a powerful DSP processor and the output signal is both in digital and analog form. DB9000-RX have built-in backup player for continuous audio play in case of signal loss or connection with server.

DB9000-RX is a professional and highly reliable IP to Audio decoder. It comes with an HTML5 based web server for device management and Ethernet to a RS-232 Redirector, enabling quick integration of the existing audio systems to the Internet. The device is available with an optional fully digital, DSP-based Stereo & RDS Encoder Module.

Supporting the compulsory for this high class equipment HE-AAC versions 1 and 2, MPEG-1 Layer 3 compressed audio streams and PCM uncompressed stream, the DB9000-RX can be used for a scope of professional audio applications: Broadcast, Internet Radio, Studio to Transmitter Link and VoIP.

The powerful DSP processor and either digital or analog output signals allow for the decoding process to be accomplished in real time which makes the device compatible with any online radio system, including Icecast and Shoutcast. Another impressive addition to DB9000-RX features is the low latency Real Time Protocol (RTP) connection support.

Along with its main IP audio source DB9000-RX comes with several IP audio sources and a built-in MP3/AAC Backup Audio Player for higher stability. The device has a built-in FTP server and 2GB SD card where the audio content for the MP3 Player is recorded. The backup audio files can be easily managed anytime remotely via any FTP client.

If the audio signal of the main source disappear, the device will switch to the first available IP audio backup source. If none of the audio backups are available then the MP3 Player starts. While when the main audio signal is recovered, DB9000-RX will automatically switch back to it. Depending on your needs, the sequence of the backup audio sources can be easily changed.
