Analog vs Digital Volume Difference?

[cpals]

I'm sure this has been answered before, but I cannot find it.

I just got done setting up my equipment and everything works, but my analog inputs (htpc and ps2) are a lot louder than my optical inputs (hd-a3 and tv). Is this normal? I had to make the analog inputs -12db to try and not get a big sound difference when changing inputs. The radio is a lot louder than all the inputs.

Equipment:
Onkyo 605
R50s L/R
CSi25 Center
Toshiba HD-A3

Also, in the onkyo manual it says something about changing the impedance to 4ohms if any of the speakers are 4-6 ohms. The csi25 is 4ohm but the r50s are 8ohms. However, I do not have that selection in my menu.

Thanks.

The problem with analog is that it can have different input levels into the receiver. Depending on the device, this can vary greatly. Some receivers may have a compensation for this depending on the input but I am not aware of any unfortunately.

That's normal. It isn't that their digital, DD and other digital formats are running full blast all the time and use the dynamic range better (softest to loudest).

there should be a switch near the speaker output for 4/8 ohm.

The idea of a volume know is to make the input louder or softer. It should be a goal to have all sources at the same level, it will depend on the recording.

You mean the speaker output on the receiver? I don't think theres any kind of switch for 4/8ohm.
