Mesa D800 without cab DI only

Green is good. In general, do class-d power amps have a standby mode that allows it to save energy if it is not being used? Phones do this.
Generally not, because if the amount is being used as a preamp/di, the power supply still needs to operate. The class D section draws very little power when not being actively used.

If the amp’s not being used, shutting the power switch off saves 100% of the energy.
