Hi again, I've a simple question: on the AMP4 board, there is a label that says "18v" by the powering screw terminal. But on the specs, it says that the AMP4 can be powered up to 24v (and 20v is recommended).
I want to double check if this is also true for the screw terminal (before I burn it up), or does it have a cap at 18v?
Thanks!
You can use up to 24V on both (barrel jack and screw terminal), but we recommend to stay below 24V as some 24V power supplies output higher voltages on low load.
I power my amp4 with a Topping P50 linear power supply. This give only 15V, but it sounds beautiful. It has enough power for my C-Note bookshelf speakers.
