1.1 Audio processing
Routed audio can be delayed up to 0.68 seconds per side, inverted, muted and processed
for error correction and data packet management.
Assigning delay
In general, as the block diagram below for Mode 1 shows, embedding and external output
routing have separate routing matrices on each side.
TANDEM-200 (Mode 1)
Since there is only one delay module available for each SDI circuit, delay cannot be
assigned simultaneously to both the embed router and output router.
For example, if an embedder is ON and has delay assigned to it, delay cannot also be
assigned to an output router on the same ‘side’. The embedder audio group control used to
select one of four audio groups can also be used to turn the embedder OFF. This will
allow the delay function to be assigned to the output router.
This logic applies to Modes 1, 2 and 4. Mode 3 has only a combined embed router so all
audio paths through that router may have delay assigned.
