Expansion options for Soundcraft digital mixing consoles

Mini Stagebox
When you don't need the modularity and configurability of a larger system, the Mini Stagebox provides a lower-cost stage connectivity solution. Used with the Si Expression's optional MADI interface card, the Mini Stagebox 32 (3U) features 32 analog inputs and 16 line outputs, while the Mini Stagebox 16 (2U) features 16 analog inputs and 8 line outputs.
Compact Stagebox (CSB)
The Compact Stagebox is a configurable modular unit, offering a high density of I/O connections in only 4U of rack space. It provides cost-effective I/O capability extension and allows connection to popular digital formats, including CobraNet®, AVIOM A-Net®16, Ethersound, ADAT and RockNet. The standard configuration offers 32 mic/line inputs, 8 line outputs, 8 channels of AES/EBU outputs and 2 expansion slots.

Various Soundcraft ViSi Connect option cards can be added to the 64x64 card slot on the rear panel of the Si Expression console, enabling interfacing with other digital systems.



MADI
The optional MADI I/O card enables linking the Si Expression to any Soundcraft stagebox and can establish a 64-channel MADI input and output for increased I/O power and flexibility. Single-mode optical, multi-mode optical and Cat5 versions are available.


CobraNet®
The optional CobraNet card enables sending and receiving up to 32 audio channels to and from a CobraNet digital audio network.


AVIOM A-NET®16
The AVIOM A-NET 16 card enables the Si Expression to digitally feed 16 mono signals to any number of Aviom personal mixers connected in a daisy-chain configuration, providing audio and synchronization data to the chain. DIP switches enable test tone generation and the grouping of two adjacent channels into one stereo channel.


AES (XLR)
An XLR-based I/O card provides two pairs of AES/EBU inputs and outputs (4 in/4 out).


AES (D-Type)
A D-type connector-based I/O card has 8 inputs and 8 outputs. A BNC connector is provided for wordclock output.
