When using Micro MPX for a single frequency network, what's the best way to make sure the pilot is synchronized at all sites? In our case, ST sends out uMPX from the studio to 2 transmitters, which gets decoded by PCs using ASI-5810 cards. The MPX audio is sent to each respective Nautel transmitter by MPX over AES. Since each sound card generates its own internal 192kHz frequency, I would imagine that the both pilots are not operating at precisely the same frequency. Is there a way to sync the sound cards to a common reference frequency? Or is this unnecessary?
