Soundcraft Si Cat 5 MADI Dual Port Option Card

The Soundcraft Si Cat 5 MADI Dual Port Option Card is a purpose-built expansion module that adds MADI (Multichannel Audio Digital Interface) connectivity to Soundcraft Si series digital mixing consoles. MADI is an established standard for transporting large channel counts of digital audio over a single connection, and this card's use of Cat 5 cabling makes it a practical choice for venues and production setups where running affordable, readily available Ethernet-style cable is preferable to fiber optic or coaxial alternatives. The dual-port design provides either two independent MADI connections or the ability to configure a redundant link for added reliability during critical events.

Designed to work in conjunction with Soundcraft's Compact Stage Box (CSB), the card enables remote I/O expansion by transporting audio channels digitally between the stage and the front-of-house console position. This eliminates the need for heavy analog cable snakes and preserves signal quality over distance. Installation is straightforward, as the card slots directly into the option card bay of compatible Si series consoles. For live sound engineers and installed-system integrators working within the Soundcraft ecosystem, this card provides a clean and efficient path to scaling their console's connectivity.
