Hi All! First time posting on here so please bear with me. I just received my new XLS802D and noticed that channel 1 made a popping sound thru my sub when shutting the amp down. (I know the LOFO routine). If I turn the attenuators all the way down there is no popping sound. BTW Kevin G if you read this ,yes it has gotten louder. Just wondering what the latest scoop is on this problem. I see another thread related to this has been locked.
