Hi Max,

Yes, the LS-10 is quietest on maximum gain, but as previously discussed her=
e, it is still quite enough at a lower gain (SENSE LOW), level 10 for most =
situations.

>On the basis of this understanding, and accepting that the iRig is a cheap=
 bit of kit, is why I set LS-1O to max gain and use the iRig to set levels.=
 This ensures that the higher level gain noise of the iRig is kept at the m=
inimum possible noise level for the recording in hand; am I correct?

No, this is unfortunaetly not true. The problem is that you insert the real=
ively noisy iRig preamp into the signal chain, which will finally increase =
the overall (input-referenced) noise floor.

It is usually the very first preamplifier stage (the iRig in this case) tha=
t determines the overall noise performance of any analog signal processing =
system.

Cheers,
Raimund
