Si Option Slot and Option Card User Guide V2.12 0813
Si Series AES Cards
The AES I/O cards offer standard AES inputs and outputs conforming to the AES 3 specification. The card is available
in two versions either 4ch IN and 4ch OUT on XLR connectors or 8ch IN and 8ch OUT on a 25w SUB-D female
connector.

Input Switch Settings:
CH IN 1-8 – AES channels 1-8 [1-4] feed expansion bus inputs 1-8[1-4]
CH IN 9-16 – AES channels 1-8 [1-4] feed expansion bus inputs 9-16 [9-12]
CH IN 17-32 – AES channels 1-8 [1-4] feed expansion bus inputs 17-24 [17-20]
CH IN 33-64 – AES channels 1-8 [1-4] feed expansion bus inputs 33-40 [33-36]
Output Switches Settings:
CH OUT 8 – Expansion bus outputs 1-8 feed AES outputs 1-8 [1-4]
CH OUT 9-16 – Expansion bus outputs 9-16 feed AES outputs 1-8 [1-4]
CH OUT 17-32 – Expansion bus outputs 17-24 feed AES outputs 1-8 [1-4]
CH OUT 33-64 – Expansion bus outputs 33-40 feed AES outputs 1-8 [1-4]
NOTE:
Numbers in [Square Brackets] relate to the XLR version of the card
NOTE
: Although an AES card may have fewer channels than the expansion bus group enabling the switch occupies all
the channels within the expansion bus group to which it is enabled e.g. if enabling group 17-32 there will be no audio
on expansion bus channels 25-32 [21-32].
