the creative.com knowledge base search revealed:
Line In Full Scale Input 2.0 Vrms
Line In Impedance 10k ohms
what is Vrms? I guess it has something to do with voltage... should
2.0 Vrms play nicely with 150mV?
Root Mean Square, which technically means the DC voltage that develops
the same power in resistive load as the AC signal would... a sort of
average and a reasonable way of comparing volume levels.
No, it wouldn't play nicely - your 150mV output is, as shown, rather low
for an input that expects 2V and that explains ithe low levels you are
seeing.
looks like headphones output works pretty well. I
don't get
unprocessed signal (i.e. volume, treble/bass, effect (dolby, room
type...) etc. are all there so I have to be careful about the settings
on the receiver) but the signal is strong enough (matching what
soundblaster expects).
any comments? gotchas?
As you say, the volume and other controls affect it - but that's the
only problem, and you can live with that - just don't touch them once
set up correctly!
