I have TRIED to set two differing brightness levels, but it doesn't appear to be sensing when I change the lights.

I've gone into the fader menu, set the display at 100, exited back to the default (no menu) state. Turned lights on, gone into the fader menu, set at 70%, exited completely out. When I turn the lights back off, the fader is still set at 70.

I'm pretty certain that the empeg knows the difference between home and car, as fader is showing up, and the EQ displays 4 channels as opposed to the 2 for home use.

That's why I was hoping to determine if the electronics of the unit was actually seeing the state change. Multimeter tests certainly look like my soldering on the install was good (checking on the ISO plug outs).

I've noted that Displayserver shows various power levels on it's web page, but I don't know where it's pulling that info from.

Thanks
