Si Impact Firmware

About the Soundcraft Si

Si Compact, Si Expression, Si Impact and Si Performer put Soundcraft's processing into fixed-format frames for installation, house-of-worship and small-venue work. Si Impact adds a 32-in/32-out USB interface; Si Performer adds DMX lighting control. Firmware is loaded from USB media.

How Soundcraft ships firmware

Ui-series updates are applied through the browser interface itself, while Vi and Si consoles are updated from USB media. Soundcraft rotates older downloads off its support pages fairly quickly, which makes an independent mirror genuinely useful for anyone maintaining an older desk.

Verifying what you download

Every Soundcraft Si Impact file in this archive lists the SHA-256 checksum recorded the moment we mirrored it, plus a link to the original Soundcraft source URL. Before loading firmware onto a console, run shasum -a 256 <file> (macOS/Linux) or certutil -hashfile <file> SHA256 (Windows) and compare it to the value in the table above. If they differ, do not load the file. More on how this archive verifies files →
