I have two Presonus ACP 88s compreser limiters on my bench . And some of the closed gate LEDs are lit. I have tried to reset them to no avail. Presonus will not relinquish any schematics on this unit , as it is still considered to be an item thats still worthy of being repaired by them. Please if anyone on this site has any schematic of any kind on this unit it would be greatly appreciated. Thanks.
