I did a function a few weeks ago and was told last night and at the function that there were times that the highs were screaming. He's what i'm using. The Denon DN MC 6000 controller. 2 Yamaha DSR 115 tops and 2 DSR 118 subs. I wanted to know how to i cut down on the highs so they aren't screaming out at everyone. On the controller i keep the highs, mids and bass knobs at 12 o'clock. I don't go past that. On the back of the tops there are no seperate knobs to control the highs, mids or bass. I was thinking of checking how the settings are for the amp and make sure that it's not running too high. What i mean is that the volume knob on the back is very low and i like it to be 12 o'clock. Might just have to use different settings in the back to control the volume instead of what they are set for now. Any suggestions.
