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.
