Focusrite Scarlett 2i2 Gain Question
#980257 - 04/04/12 10:53 PM
I got this bus powered USB interface to use with a laptop for portable recording and it
seems to work quite well with Windows 7 and Reaper. Regarding the gain knobs, there is
some signal input even with the knobs all the way down. It may not matter but I've never
come across this before. Anything to be concerned about? Thanks.

Nothing to be concerned about -- it's
quite normal. The gain knobs are exactly that -- they adjust the gain of the preamp over a
specified range, which the handbook says is +10 to +55dB for mic inputs, and -10 to +35dB
for line inputs.
So there is always at least 10dB of gain provided for mic
inputs -- it will never turn of completely. This is quite normal.

In the less than stringent guitar amplifier industry you will encounter controls labeled
"gain" when in fact they are nothing of the sort but are "interstage volume controls" and
these controls will fade to zero.
Some amp makers even "cheat" a little and
arrange for the control not to take the signal quite to zero but this is a trick! It is
not a proper gain control (which uses negative feedback to alter the amplification factor
of the stage) but a "pot" with a setup resistor in its lower extremity.
is a lot of smoke and mirrors in this audio lark mate. Keep asking!
