Doh! Ok, I put a piece of tape down and that seems to have solved the problem. Thanks!

Hi. I just built my mini3 but I am concerned about the volume. I am about to get a lod for my ipod but am connecting it to my ipod from the minijack output for now. The music coming out sounds normal and good, but I have to raise the volume on my IPOD to get a reasonable output level from the amp. What could be the reason for this low output? It passed all initial checks with flying colors by the way.

You should use a LOD instead of taking the headphone out. The LOD is a true line out and is not affected by the iPod's volume control.

Any amp expects a certain input voltage level. As AMB said it is best to use the iPod LOD to get the best sound possible out of the iPod. However if you are using the headphone out, I found the best sound came from the iPod when the Volume was set just below MAX.

Yeah you are right. If anything now the volume can get too loud with the LOD. Thanks. This is a great project!
