On mine. there is a single push button on the front that will turn the unit on and into standby. There is a rocker switch at the back that turns the unit on and off.
The green light at the front of the unit shows if the amp is on or in standby. With the 12v trigger installed, the unit just sits on solid green (turned on) and just won't go into standby mode.

I have tried that maybe I need to turn off/on the rocker with the trigger cable installed, and that made no difference. Tried putting it into standby mode with the pre-amp turned off, and then see if it comes on when the pre is turned on. Nope. Tried routing the cable through the EP500 just in case the power signal wasn't getting through. The EP500 turns on and off perfectly, but not the ADA.
