More details

More info

Professional high quality DSP hardware audio encoder MAGIC AE1 DAB + Go is realized as a fanless device ½ x 19 ''. Some audio interfaces analog and digital are available for audio signal input. The Windows software supplied allows the configuration of up to to 40 systems.

In addition to the usual PAD power supply via the multiplexer - which supports all standardized services - the PAD services Dynamic Label Via FTP or UECP and Slideshow via FTP can also be fed locally on the device. In addition, a traffic announcement ( TA ) can be triggered very easily via UECP or a GPI contact. Finally, the audio encoder allows direct transmission of the program type ( PTy ) like Rock, Pop etc. via UECP.

The transmission is monitored via the supplied Windows PC software or SNMP. Alternatively, an alarm can also be issued via a GPO contact.
