The MAGIC AD1 ETI decoder enables monitoring of the DAB transmission signal at any location in the ETI/EDI distribution network.
The system can either be patched in directly to the ETI (NA, G. 704 and NI, G. 703)2-Mbit/s signal to be monitored or connected parallel to the signal. Optionally, the connection can also be made via EDI. In case of failure of the device, the 2-Mbit-connection is bridged via a relay.
All audio programs contained in the ETI/EDI stream are monitored, whereby one of the programs can be decoded and listened to.
Additional ETI decoders can be cascaded via the 2-Mbit/s output so that several programs can be decoded at the same time.
The audio signal can be output in analogue and digital (AES3). There is also a headphone output.
The display shows all available programs as a list. Switching between the audio programs is done by simply pressing a button on the device. All relevant information on the currently selected programme can be retrieved.
Two relays and six GPIO contacts are available for external signalling.
In addition, all alarms can be stored internally in the system with date and time without PC.
The integrated LAN interface allows the system to be controlled and monitored. SNMP is also used to integrate the system into a network management system.
The possibility of extracting any program from the DAB ensemble allows a cost-effective audio program feed for non-DAB applications without the need to use additional transmission lines. This allows FM audio programs to be transmitted to station locations and audio programs to be fed into cable networks.
The supplied Windows PC software enables detailed error monitoring, decoding of the ETI data stream and reading of the error memory. All relevant information, such as 2-Mbit alarms, number of subchannels, subchannel types, etc., are displayed in a very clear way.
Optional ist eine zweite LAN-Schnittstelle verfügbar.
Mit der Option EDI kann ein EDI-Signal über die LAN-Schnittstelle zugeführt werden.
