With outboard units with digital options fitted, why does the digital audio output intermittently drop out?
All analogue outboard units must be supplied with a valid sync source if they have digital options fitted, to enable the digital output to be in sync with the rest of your digital studio setup. The following should be observed to prevent digital output audio drop-out. 1. If a unit receives a Wordclock sync source (via the Wordclock In BNC connector), and there is nothing connected to the Wordclock Out BNC connector, the 75 termination switch should be in the correct position. 2. In setups where multiple units require a sync source, a ‘star’ system should be employed rather than a ‘daisy-chain’. In a star system, a cable goes from the sync source directly to each unit, and each unit has it’s wordclock terminated. In a daisy-chain system, a single cable supplies the first unit from the sync source (IN), which is then fed into the second (via the OUT BNC on the first, to the IN on the second), then OUT of the second and IN on the third etc.
