My apologies if this is a stupid question. I've been struggling to find the answer through the rather large threads..

On the PSU Schematic, on the protection circuit we have "TO IN (DC SENSE, INTERNAL)" and "TO AC (AC LOSS SENSE, INTERNAL)".

My question is: what are these inputs looking for in terms of voltage etc?

I intend on using this PSU on an Apex amp build that I'm currently working on so I'm trying to figure out how to interface the two.

TO IN (DC SENSE, INTERNAL) - senses DC at amplifier output. Internally connected to "IN" terminal of protection sections.

TO AC (AC LOSS SENSE, INTERNAL) - senses loss of AC at power off and quickly resets the protection circuit so that if power comes back soon the usual delay between power-on and speaker-on is retained. Internally connected to AC input of the PSU section.

Connect output of amp to the "IN" terminal and connect speaker's input (+ terminal of speaker) to the "OUT" terminal. Connect speaker return (- terminal of speaker) to one of the five GND output terminals.
