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.
TheoryofOperation:
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.

ExampleConfigurations:
An example of a valid configuration:
64 Channel
Input
Expansion
Bus
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
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.
< 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
< Card #1(AES) INPUTS 1-8 active
< Card #2(MADI) INPUTS 1-64 active
A typical example of an output configuration:
64 Channel

Bus
> Card 1(AES) Outputs 1-8 Active
> Card 2 (MADI) Outputs 1-32 Active
>Card 3 (MADI) Outputs 1-64 Active
CardSwitchSettings:
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.
SiSeriesOpticalMADICard
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.
The auxiliary interface can be used as a redundant link.
Specifications
Max. cable length multi-mode fibre 1300 nm 2 km
Input frequencies 48 kHz ±100 ppm
Current consumption (3.3 V) 0.4A
(5 V) 0.4A
Operating temperature 0...45° C
Switch Settings:
Input Switches:
CH IN 1-8 – MADI channels 1-8 feed expansion bus inputs 1-8
CH IN 9-16 – MADI channels 9-16 feed expansion bus inputs 9-16
CH IN 17-32 – MADI channels 17-32 feed expansion bus inputs 17-32
CH IN 33-64 – MADI channels 33-64 feed expansion bus inputs 33-64
Output Switches:
The switches have no function; all expansion bus outputs feed MADI channels 1-64
SiSeriesAESCards
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.
NOTE: The SUB D version includes a Word Clock Out on a 75R BNC connector.
Specifications
Input/output impedance 110 Ω
Input sensitivity min. 0.2 V
Output level (into 110 Ω) 3.3 V
SFC range 22...108 kHz
Operating temperature 0...45° C
Pin Configurations:
SUB-D Connector
XLR Connectors:
PIN#1 GND
PIN#2 HOT
PIN#3 COLD
Switch Settings:
Input Switches:
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:
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].
