[. . . ] 5 Version: V1. 1 Supported Cards: OPTICAL MADI AES Introduction: The Si series of consoles feature a versatile 128 channel expansion bus offering 64 discrete additional input sources and 64 additional output patches that may be used in parallel to fan-out to multiple destinations. Routing from the cards to the processing channels and from channels or buses to the option card buses is achieved via the `Patching' functionality; see Si User Guide for details. Theory of Operation: Inputs ­ All of the 64 expansion bus inputs are present at all expansion slot positions, and any card may talk to any bus however only one card may be set to `speak' to any one bus at any one time. For example if you require 64 inputs from a MADI card then no other input cards may be active at the same time; see `DIP SWITCH SETTINGS' for your option cards for details on how to activate / de-activate routing. Registered Office: Harman International Industries Limited, Cranborne House, Cranborne Road, Potters Bar, Hertfordshire EN6 3JN. Company Registration 1485558 Example Configurations: An example of a valid configuration: 64 Channel Input Expansion Bus < Card #1(AES) INPUTS 1-8 active < Card #2(AES) INPUTS 9-16 active < Card #3 (MADI) INPUTS 17-32 active < Card #4 (MADI) INPUTS 33-64 active This configuration uses all four slots found in an Si3 / Si2 but no two cards are trying to speak to the same bus. NOTE: Si1 has only two option slots but the same principles apply. An example of an invalid configuration: 64 Channel Input Expansion Bus < Card #1(AES) INPUTS 1-8 active < Card #2(MADI) INPUTS 1-64 active In this example there is a clash between the two cards as both are trying to `speak' to buses 1-8 and the conflict must be resolved by resetting of the routing dip switches on one or other of the cards. Outputs ­ The operation of the outputs is slightly easier to understand; in this case whilst only one audio source on the console may feed any one channel of the output bus any or all of the cards may `listen' to what is being routed to the output bus. The DIP switches may still be used to limit or choose which signals the card uses in the event you do not wish all cards to re-transmit all channels. A typical example of an output configuration: 64 Channel Output Expansion Bus > Card 1(AES) Outputs 1-8 Active > Card 2 (MADI) Outputs 1-32 Active >Card 3 (MADI) Outputs 1-64 Active Card Switch Settings: This topology allows great versatility when you are required as an example to route direct outputs to multiple destinations simultaneously. The table below illustrates the function of the DIP switches found on the Si Series option cards: Setting any given input switch shall enable routing of the INPUTS TO THE OPTION CARD to the given channels on the expansion bus. Setting any given output switch shall enable routing of the SIGNALS ON THE EXPANSION BUS (outputs from the console) TO THE OPTION CARD. It is important to remember that the patching of I/O signals to / from the expansion bus is unrelated to the setting of the physical switches on option cards; the card switches dictate only which channels of the option card bus the expansion card can monitor / talk to. NOTE: There are some exceptions to the above, please refer to the Switch Settings section of each card type for full details. Si Series Optical MADI Card The MADI I/O card can establish a 64-channel MADI input and output to a remote device such as stage box or other equipped device. Optical inputs and outputs are provided on SC connectors available in multi-mode versions only.
