Which buttons control the output to the SB in the console?

The correct option highlights that the buttons controlling the output to the SB (sub-bus) in the console are found within the BAM (Bus Assignment Module). The ST A B or C buttons allow the user to specifically assign or route the main stereo outputs to different sub-buses. This function is crucial for managing how audio signals are mixed and sent out, allowing for precision in the audio workflow.

Understanding this provides insight into the mixing console's operational logic, as certain assignments are essential for achieving the desired audio effects or routing necessary for both live sound applications and recorded productions. The ability to manipulate these outputs is a fundamental aspect of monitoring and mixing audio signals effectively.
