I tried following the math a few pages back to figure out how to set my system up but I got totally lost.
Here's what I know:
I have an Emotive MPS-1 (and DMC-1 Pre/Pro, but contemplating taking that out of the system and using my 105D lieu of it) and here are the specs I was able to track down:
The reviewer measured the voltage gain as:
Unbalanced: Av = 27dB
Balanced: AV = 26dB
and said, "It took about 1.65Vrms to drive the MPS-1 to full power."
When I connect my 105D to the amp directly I have to keep the volume down to around 60. I saw a recommendation to get some attenuators so I'll dig back through the thread to see which ones to buy unless someone posts suggestions in response to my post.
In the meantime, however, what would be the effect of reducing all of my speakers' trim levels by 10dB? Does this make an effective -10dB attenuation or does it reduce the fidelity in the same way as turning the volume down -10dB?
This question stems from what I thought I read about turning down a digital volume control and its relationship to the DACs' bits thereby resulting in reduced fidelity at low enough volumes. If I understand that relationship relatively accurately, does it hold true when I turn the volume down via the trim levels? Also, are there other considerations in doing this?
-10dB via trims gives me 20 volume clicks to adjust, correct?
