Si Series: Stereo Matrix Audio Loss on Right Control Room Monitor Channel
Table of Contents
Brand:
- Soundcraft
Affected Products:
- Soundcraft Si Series Consoles (Si Impact, Si Expression, Si Performer)
Summary:
- When routing audio from the Stereo Master to a Stereo Matrix bus on Soundcraft Si Series consoles, selecting the matrix feed via TOTEM for Control Room (CR) monitoring may result in the right leg of the stereo audio signal being dropped. This issue affects confidence monitoring only; actual physical Matrix outputs function normally. Installing firmware version V2.1 build 5 or higher resolves this monitoring routing bug.
Troubleshooting:
- End-User Action:
- Download console firmware version V2.1 build 5 (or newer) from the official Soundcraft website.
- Install the firmware update via USB flash drive following standard console software update procedures.
- Re-test Control Room monitoring selection on assigned Stereo Matrix feeds.
- Resolution: Update console firmware to version V2.1 build 5 or higher.
- Verification: Press the MTX TOTEM button to solo/monitor the Stereo Matrix feed in the Control Room monitors and confirm stereo audio is present on both left and right monitor channels.
