Figure 2.4: Using an audio processor for SPS synchronization
If the Importer Plus will not be co-located with the NE IBOC, Exporter or Exporter Plus, you can
purchase a second GPS synchronization unit to install near the Importer Plus. Both units must be
GPS locked to satellite. Since the GPS synchronization unit can only synchronize a single audio
source, you will need to use the GPS synch word clock, or a spare AES output, as an input to a
sample rate converter (audio processor) if you are using more than one SPS. See Figure 2.5 on page
2-8 for a block diagram of this setup.
