Ok, I just got my SVT 4 today. I noticed in mono bridge mode (using a AMpeg 4x10 HLF) that there is more noise then my SVT 3 pro. Is this normal since it's much more powerful? I also tried it using mono mode pluging into Power AMP A with just 1/4 inch to 1/4 inch and same results. I'm pretty sure it just outputs more noise because it's much more powerful but I just want to make sure.
