Recently purchased a power sequencer to try to fix the loud thump/pop/screetch when a Xs4300 is powered down. Unfortunately, it didn't help - even though the amp is powered down before the mixer and everything else, still get a pretty loud pop.
However, there is no thump when the amp is first powered down with the amp's power switch.
Is there any kind of fix that would allow for a quiet power down when the external power is removed?
