General Information
DB9000-STC is a high-performance, 32bits DSP based Stereo Generator with built-in RDS/
RBDS encoder. It has been accurately designed to satisfy the most demanding requirements in FM
Stereo generation and advanced RDS/RBDS encoding. This Stereo Encoder accept both of types,
Analog and Digital AES/EBU audio sources. DB9000-STC comes with easy to use and password
protected Web Server and a comprehensive remote control features. It supports SNMP, RS232,
UDP, TCP/IPcommunication protocols. Its digital architecture guarantees long term reliability and
easy rmware updates, directly on eld or from remote.
The built-in RDS encoder can ‘parse’ scrolling text, automatically breaking phrases into word
groups. It gives dynamic, on-the-y programming access with its built-in USB, TCP/IP, UDP/
IP interfaces. This connectivity permits full integration of RDS/RBDS transmissions with the
station’s other networked functions, including message streams for digital radio and Webcasting. It
can be easily interfaced to variousAutomation Systems and offers anASCII protocol for broadcast
song/artist information.
Another great feature of the DB9000-STC is that it can ght the dreaded dead air problem.
The DB9000-STC provides additional uncompromising security in case of loss of audio at the
audio inputs. The audio backup is presented as an integrated built-in MP3 audio player. The basic
principle of operation is that this unit can detect the silence and switch the output to the alternative
MP3 Player. The MP3 backup audio les and play lists can be uploaded in the device from your
PC using any FTP client. The audio storage capacity of DB9000-STC is 2 Giga Bytes.
Based on the latest DSP technology, the DB9000-STC is fully digital design for 24/7/365
operation. This product is the most cost effective, versatile and reliable solution designed for the
broadcasters looking for a complete solution for a single, or a multiple transmitter sites.
