I've struggled with this for many hours, and now I leave it with you guys
I'm not a PRO, especially not with all the settings on an amplifier.
I want to upgrade my soundsystem from a 4channel amp to a 5channel amp of the same model, and then build a Cubo15 extendend. (you can see it in the video)
The horns makes a high pith noise on the new amp (Precision Power P900.5). There's no problem when I use the old amplifier (p900.4).
I think the sound is a little stuffy, if that makes sense. Also I have a hard time hearing that theres coming some low frequencies out the 15" speaker.
Maybe the amplifier is broken, or maybe i'm just too stupid to figure out the right settings for the p900.5 amplifier.
This is a video, bare with me for the really bad english and the danish accent
I hope you can help me out. I've got 2 months until Roskilde Festival kicks off
