Page 24: Synchronizing The Sps Sample Rate
Additional equipment General considerations You can achieve the best SPS audio performance if you synchronize the Importer Plus’ 44.1 kHz audio sample rate to the master clock of the HD system. The difference in audio quality may not be perceptible, or even important, given that SPS channels are typically lower quality audio. To synchronize, you may require considerable equipment infrastructure (see “Using an HD-4 audio...
