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/IP communication 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 various Automation Systems and oers an ASCII 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 eective, versatile and reliable solution designed for the

broadcasters looking for a complete solution for a single, or a multiple transmitter sites.
