Thanks!
Yes I noticed that it increased with the latest iteration of the sound system. Previously I was using high level inputs and didn't notice it as much. Gains set using SMD-DD1. 0db 1000Hz for head unit, -5 db 1000Hz for the PSM and Amp gain settings. It is only really noticeable at low or no volume.

Thanks for the input.

 

I think some of the tech nerds at ARC recommend the master gains to be in the -10 range or possibly less but there seem to be tons of different ways to currently skin this cat.

Wow! that's a big difference from what I have it set at in the PSM
Fronts and Rears at + 5.5 (where the SMD-DD1 shows distortion at -5 db 1000Hz), then very little gain at the Arc 600.4 amp

Horns set at -10 (Small kenwood amp had no gain control) still has some small gain hiss at low/no volume

BTW I have all of this crammed in the fairing of a 15 Road glide (except for the VO-M6x9s that are in bag lids) so getting to the gain settings of the Arc 600.4 is going to be a nightmare again.

 

More food for thought, thanks T.

 

I have a ton of floor noise with my ARC. Tried a few different settings. So I thought about it for.......about 2 seconds and just decided to crank up the tunes and leave it! I don't hear it then .

 

Anyone using a subtractive EQ strategy vs additive EQ strategy?

T

 

I am, for now at least.

 

I prefer to use subtractive as my baseline then additive to fine tune if needed.

 

Very cool!!!! That has seemed to help the floor noise as well. Cleaner tunes as well.

Prob 1000 ways to break the code but I'm enjoying tinkering with and learning the various strategies.

DSPs are more like the dementors Scary and when around they suck the joy out of you
I tried using them a bit, thinking I will get a hang of it eventually, but it doesn't work that way :/
