EVS Synapse UXU500, Installation And Operation Manual, Page: 60 / 72

The system makes use of the same passive copper traces on the internal bus PCB as normal add-on bus
cards.
The maximum amount of ADD-ON cards in Quad Speed mode is 3. These 3 ADD-ON cards will run all on
the same clock in the same phase as the MASTER-CARD. This guarantees that audio channels that are
processed in different ADD-ON cards will still operate in the same phase, something very important
when processing multiple discrete surround channels.
You can mix normal speed Master-Cards with Quad Speed MASTER-Cards in one frame as the MASTER-
CARD breaks the connection to the left hand card. All cards to the right of the master must be in the
same mode as the master.
Mixing normal ADD-ONs with Quad Speed ADD-ON combinations in one frame is allowed.
Example 1. Here we combine a master card that performs embedded domain Dolby E to Dolby Digital
Plus encoding. Between the E-decoding and Dolby Digital Plus encoding we want to watermark the left,
right and center channel of the decoded discrete 5.1 surround channels and watermark a PCM channel
used as a voice over for audio description.
Embedded domain Dolby E to Dolby Digital Plus with Watermarking. The only connection to the outside
world are two BNC cables.
