Being sensitive to phantom power (especially if it's over a watt, no less 58W) I'd like to propose that:

A) the DSP have a trigger which shut's it down completely ... and if there is any chance that there might be a transient on its output then the DSP also have a trigger out which shuts down the amp before the DSP (and turns it on after the DSP is settled).

B) the Amp shut off completely after say (10min). I can only guess that this is not being done because the power supply takes a while to come back up. For people who want instant on then maybe this option is switch selectable.

Thoughts?
