• Channel shuffling is done in the ADD-ON card.
The master card has only one setting to enable the quad speed audio bus.
• Every Quad-Speed ADD-ON card takes 32 channels from the ‘right hand ADD-ON card’ and adds (or
overwrites) the local processed channels.
This can be done for any of the channels that are processed in the ADD-ON card.
• Some master cards are switchable between normal and quad-speed bus.
• Channel designations on the block schematics:
Channel 1-32 (or less) are injected into the large, dark green arrow from the master card to the ADD-
ON card and looped onto the next ADD-ON card via the dark green arrow.
The ADD-ON card injects up to 32 channels into the large brown arrow.
An ADD-ON card will also actively loop extra processed channels into the next ADD-ON card, and
finally into the master card.
• The cross looping of the original design is now a straight loop.
• The quad speed bus can also work in one direction.
You can use a Quad Speed audio bus to de-embed audio from the master and present on the ADD-
ON card as AES/EBU, Bitstream (like Dolby) or analog audio.
If applicable, the ADD-ON card can also be used as in injection point of physical audio streams.
The ADD-ON cards also provide a looping function from one ADD-ON card to the next. This is however
more intelligent looping, with optional re-insertion and multiplexing of signals.
Cascading of Quad Speed cards works identically to normal add-on cards. Every connection in the
example below transports 16 mono audio channels (= 32 channels per color). It shows the inter-slot
connections ‘in quad Speed mode’ as part of the frame bus PCB.
The system makes use of the same passive copper traces on the internal bus PCB as normal add-on bus
cards.
