2.1 Functionality
With the MAGIC AD1 ETI Decoder an ETI output signal of an Ensemble Mul-
tiplexer can be monitored. The system allows a simultaneous monitoring of
all DAB & DAB+ Audio data streams. The system can be connected anywhere
in the 2-Mbit/s signal (NA, G.704 and NI, G. 703) to be monitored or it can be
connected in parallel with the signal path. All Audio programmes in the data
stream are monitored and an individual programme can be extracted and de-
coded. Additionally, the internal protocol file can be activated to store upcom-
ing error messages.
In case of a power breakdown the E1 signal is automatically looped back via
a relay.
The currently decoded Audio signal is available at the analogue or the digital
Audio outputs. If the digital AES/EBU Audio interface is used, two separate
Sample Rate Converters are available for automatic clock synchronisation.
For external clocking a clock input and a clock output are available.
Additionally, the ETI Decoder incorporates a Headphone interface for moni-
toring the Audio programm that is currently selected to be decoded.
