sine wave into a dead input channel. Use the block diagram and schematic to trace the physical path with an oscilloscope. If the signal is visible before an op-amp but missing after it, you have isolated a dead IC.

This section utilizes ultra-low-noise operational amplifiers. The schematic reveals dual phantom power rails split across channels 1–8 and 9–16. Soundcraft Fx16ii Schematic Diagram

If you are opening up the console to diagnose a hardware failure, cross-reference your live circuit board with the diagram utilizing these practices: Inject a steady sine wave into a dead input channel
