BLU-Si Card For Si Compact, Expression & Performer
DIP Switch Settings
The BLU-Si card features two different sets of DIP switches;
BLU Link 'On Ramp' & 'Off Ramp' Channel Assign Settings
Si Console Connect 'Channel Select' Settings
Channel Assign Switches
The channel assign switches dictate which group of channels on the BLU Link network the card ‘listens’ to and
‘speaks’ to. Looking directly at the dip-switch block are six switches numbered 1-6 (left to right). The leftmost
three switches (switches 1-3) are used to select the on-ramp (card speaks to BLU Link) bank. The rightmost
three switches (switches 4-6) are used to select the off-ramp (card listens to BLU -Link) bank. Channels not
used by the Si BLU Link card are simply passed ‘thru’.

Si Console Connect 'Channel Select' Settings
The Si console needs to know what number of channels to extract from the card and how many channels to
send to the card. The console speaks to the card to extract this information which then allows the console to
configure itself for correct operation. These DIP switch settings control this 'Chanel Select' settings for the
card. These switches can also been seen on the SI Dante Card & Multi-Digital Card.
Thankfully, with the BLU-Link card, there is only one correct setting!

NOTE : Please always ensure you have the most recent software installed on you Soundcraft Si Console
When making any physical I/O changes to your console (for example adding an option
card), always Reset IO
RESET CONFIG: Clears the console
database of any option cards or external
I/O systems that may have been attached
to the console. Reset config also forces
a ‘re-discovery’of any installed option
cards or connected I/O system such as
a Soundcraft Stagebox; see I/O Discovery
for further details. The system will provide
a warning that the action will overwrite the
current configuration database and allow the action to be aborted
