Introduction:

The Si 1,2 3 including ‘+’ 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 the console user guide for details.

IMPORTANT: Setting of DIP switches on Si 1,2,3 including ‘+’ variants is critical since the console option slots

share an expansion bus. Setting of dip switches on Si Performer, Si Compact and Si Expression is not critical as there is

an expansion bus dedicated to each option slot.

Theory of Operation:

Inputs – All of the 64 expansion bus inputs are present at all expansion slot positions; any card may route to any

expansion bus however only one card may be set to route to any one bus at any one time, as an example if you require

64 inputs from a MADI card then no routing from 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 to the expansion bus.

NOTE: There is a clear distinction between patching & routing; patching is the act action of assigning an available

signal source to a processing channel whilst option card whilst routing is the action of enabling / disabling outputs of

an option card to the expansion bus for where it may then be patched to a DSP channel.

Example Configurations:

An example of a valid configuration:

< 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 route to the same bus.

NOTE: Si1 has only two option slots but the same principles apply.
