 So the question is what is the best setting for the output volume of
 the SB3 with regard to distortion and S/N ratio? I usually have it on
 95% but I got the doubt wheter I am too close to potential clipping
 distortion of the output.
 
 One important detail is that i use the analog output.

I always turn mine up to 11. Sounds much better.

I had a weird thing happen today.  I went to squeezenetwork while I
rebooted my computer.  When I went back to SC later the volume had
dropped from 100% to -20dB.  Is that a glitch?  I keep mine at 100% but
I don't think I want to lock it for the rare times I can't find my
receiver remote and need to turn it down quickly.

[slim] What output level on the SB3 is best?

2008-08-02 Thread Aguida

I guess as most people I don't use the SB3 volume control but the one on
my stereo amp. 

So the question is what is the best setting for the output volume of
the SB3 with regard to distortion and S/N ratio? I usually have it on
95% but I got the doubt wheter I am too close to potential clipping
distortion of the output.

One important detail is that i use the analog output.

And one follow up question is: Is it possible to lock the volume si
that no one accidentally changes it again?

Thanks a lot.

Alessandro

Setting the volume at 100 will give you the best signal-to-noise ratio,
so that's the general recommendation. Just don't turn your amp's volume
too loud! With Sqeezceenter 7.1 and the new firmware it includes, you
can use the fixed output level option in Squeezecenter to lock both
digital and analog output at volume 100. I think you don't actually
lose detail until volume 70, but 70 on the SB3 is about -15 dB, so at
70 you've decreased the S/N by 15 dB. Use the Advanced Search feature
on these forums to find posts by user seanadams (company founder 
Squeezebox designer) for the best info on the subject.

If you're not using Squeezecenter 7.1 or if you want to lock the output
at a lower volume level, see my VolumeLock plugin. Basically, once you
get the volume where you want it, you can use the IR remote or Web
interface to ask VolumeLock to lock the output.

If your amp has an infrared remote control, you should also look at
Felix Mueller's IR Blaster plugin. I use this on one SB3 that's hooked
up to a mini stereo. IR Blaster fixes the Squeezebox output at a
certain level and passes volume up / volume down commands to your amp
once you acquire  set up an IR blaster infrared dongle.
