DB90-TX is an integrated audio converter that converts audio signal into a high quality compressed audio stream. The signal can be compressed by HE-AAC, MPEG-1 Layer 3 encoder. DB90-TX also supports uncompressed PCM stream in order to ensure audio transmission without quality loss. Compression is performed in real time, and the output signal is transmitted directly by IP-based networks. DB90-TX can work with both analog and digital audio signal. No matter how sophisticated, DB90-TX is located in a small and compact housing. All this allows you to quickly and painlessly integrate existing audio systems to the Internet.
DB90-RX is an integrated client for IP transmitted digital audio signal. It 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. No matter how sophisticated, DB90-RX is located in a small and compact housing. All this allows you to quickly and painlessly integrate existing audio systems to the Internet.
The best device to fight the dreaded dead air problem is the DB8000 from Deva Broadcast Ltd. It is designed and built to be simple, flexible, reliable and easy for integration with the existing setups of any single station to a large radio networks. The basic principle of DB8000 is that this unit can detect the silence and start playback of a preliminary created play list on the built-in MP3 player.
The MP3 backup audio files and play lists can be uploaded in the DB8000 from your PC using any FTP client. The audio storage capacity of DB8000 is 2 Giga Bytes.
The DB8000 provides additional security in case of loss of audio at the inputs. The audio backup is presented as an integrated auxiliary audio input for external program’s backup audio source and built-in MP3 audio player. Internal bass and treble controls module allow advanced audio adjustment of the MP3 backup audio.
The unit has DTMF remote control features. Preliminary assigned up to 3 digits DTMF tone combination can change the audio source input or just to start playing from the play list of the built-in MP3 Audio Player. Trough this feature the DB8000 can be used for local content or regional advertisement spots insertion.
"MAXIMIZER" is an MPX processor which is able to effectively and precisely control the amplitude of the signal before it is fed to the transmitter. The inclusion of a stereo enhancer after the processor will justify the addition of this component in the transmission chain. The stereo enhancer should be inserted after the processor for maximum effect; this will, however, alter the stability of modulation defined by the processor. Another device is thus required to restrict this parameter between acceptable limits.
Whoever works with composite MPX signals will know only too well the sensitivity of the parameters involved; MAXIMIZER effectively controls amplitude (and therefore also modulation depth) without having any effect on the quality of the output signal.
