DiGiCo SD11 troubleshooting
The DiGiCo SD11 problems live-event techs bring to Ask Roadie most (also called SD11 console). Pick your symptom, or describe your own in plain words, and get the likeliest fix first, with the manual page when there is one.
Common SD11 errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.

Converting a session from SD12 to SD11 loses the MADI BNC port / other convert quirks
Likely cause: The MADI-port deletion on convert was a known software defect resolved in the V2126 release; running current software plus the matching convert tool avoids it.
- Step-by-step fixGet the fix →
External MADI/rack device will not achieve clock sync with the SD11
Likely cause: Forcing Main/Aux priority removes ambiguity about which port supplies clock.
- Step-by-step fixGet the fix →
Need 64ch Dante on an SD11
Likely cause: The Dante capability was added in the V2126 software cycle; older firmware will not enumerate the Fourier card.
- Step-by-step fixGet the fix →
No +48V phantom power reaching a condenser mic on SD11/rack input
Likely cause: The rack socket has a dedicated orange LED for phantom state; using it confirms 48V at the hardware rather than trusting only the on-screen toggle.
- Step-by-step fixGet the fix →
No input signal / channel not showing from a D-Rack or SD-Rack
Likely cause: Isolates the fault to cable, patch, or clock.
- Step-by-step fixGet the fix →
Random clicks/pops or 1–10s dropouts on SD11 MADI (BNC) outputs feeding a MADI router/PA
Likely cause: MADI clicks/dropouts are almost always a clocking mismatch or sample-rate mismatch between the console and the downstream MADI device.
- Step-by-step fixGet the fix →
SD11 fader behaving erratically / not tracking position — is calibration needed?
Likely cause: Cleaning addresses the actual cause without risking the fader reference.
- Step-by-step fixGet the fix →
Split/gain-tracking outputs: analog gain changes on input are affecting a FOH/monitor split
Likely cause: Gain Tracking is the mechanism that lets two consoles share one set of preamps without one engineer's gain moves changing the other's levels; the rack LEDs confirm its state at the hardware.
- Step-by-step fixGet the fix →
What are the SD11 core specs and I/O?
Likely cause: Baseline reference so techs know channel/bus/IO limits before patching.
- Step-by-step fixGet the fix →
What is the current SD11 software/firmware version and how do I update?
Likely cause: V2126 is the newest confirmed release and adds Fourier (Dante) card support to SD9/10/11.
