Core spec / processing recap: channel, bus, matrix and FX counts on the Quantum 225
Likely cause: Figures taken directly from the manufacturer data sheet and A&E spec; these are the fixed processing limits of the platform.
- Step-by-step fixGet the fix →
Optocore / optical loop options and capacity
Likely cause: Optocore is a closed ring; a mode mismatch or a broken/reversed fibre run leaves the loop unlocked, which is the most common optical fault.

Ticks, dropouts or unlocked I/O across a multi-device rig - clocking best practice
Likely cause: Two masters or a sample-rate mismatch produce slips at the buffer boundary; a single reference clock eliminates them.

Virtual soundcheck / multitrack record and playback via UB MADI
Likely cause: UB MADI removes the need for a separate MADI-USB bridge for basic 48ch capture/playback, which is why it is the standard route for virtual soundcheck on this desk.

Waves SoundGrid card setup and clocking
Likely cause: A single defined clock master between console and SoundGrid prevents the ticks/dropouts that come from two masters fighting.

Worksurface layout, faders and the customisable left bracket
Likely cause: Manufacturer worksurface description; the assignable-layout and bracket are the defining features versus fixed-layout consoles.
