DSP-Based Stereo Generator with RDS/RBDS encoder
The DB9000-STC is a fully digital, DSP-based Stereo Generator with built-in RDS/RBDS encoder. It supports TCP/IP and SNMP communication protocols, and allows full integration of RDS/RBDS transmissions with the station’s other network functions, including message streams for digital radio and Webcasting. It also offers an ASCII protocol for broadcasting song/artist information. Thus, the unit can be easily interfaced to various automation systems.
The DB9000-STC is intended to fight the dreaded dead air problem. In case of audio loss, the unit will detect the silence right away and switch directly to the integrated built-in MP3 audio back-up player. The audio files and playlists can be uploaded to the device from your PC via any FTP client.
Developed with the goal of easiness of use, the DB9000-STC can be managed through a standard Web browser, PC, PDA, or other device, which makes it the best choice for professional and consumer use.

DB9000-STC is a high-performance, 32bits DSP based Stereo Generator with built-in RDS/RBDS encoder. It has been successfully designed to satisfy the most demanding requirements of FM Stereo generation and advanced RDS/RBDS encoding. This Stereo Encoder accepts both, Analog and Digital AES/EBU audio sources. DB9000-STC comes with an 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 firmware updates, directly on field or from remote.
The built-in RDS encoder can 'parse' scrolling text, automatically breaking phrases into word groups. It gives dynamic, on-the-fly 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 offers an ASCII protocol for broadcasting song/artist information.
Another impressive feature of the DB9000-STC is that it can fight 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's backup audio files 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 digitally designed for 24/7/365 operation. This product is the most cost effective, versatile and reliable solution designed for the broadcasters looking for a customized solution for a single, or a multiple transmitter sites.

How can I access the internal storage and upload tracks?
DB9000-STC has a built-in backup audio player. In case of main audio signal loss it plays tracks from the SD Card storage uploaded over the FTP. An FTP client should be used in order for the internal storage of DB9000-STC to be entered. For further information on the FTP Server Settings, please refer to the Quick user guide. An important requirement for the MP3 Player configuration is that all MP3 files should be stored in a single folder named Audio. The folder should be located in the root of the SD Card. The playlist file has to be named playlist.m3u. Please note that subfolders are not allowed.

Why the alternative frequencies (AF) that I have set are not transmitted?
DB9000-STC is controlled trough a build in WEB Server and a standard web browser can be used to monitor its status or to make some adjustments. Once you have accessed the WEB Interface, in order for the needed AF adjustments to be made, go to MPX section, then select AF List subsection and set a number of alternative frequencies. Then, if for example you have specified 3 AFs, the 4th AF should be set as disabled. The disabled AF is considered as the end of the list and AFs after it will not be transmitted. Please note that If AF 1 is "Disabled" the list will NOT be transmitted.
