As is commonly known, quality audio processing starts with enough current headroom (available current for musical peaks!) to supply the most extreme audio swings on demand. With the wide variety of processing modules available for the 9000 Series, it might be necessary to calculate the current consumption of your modules to make sure that the audio quality is not compromised by the limits of the power supply.
