My preamp has a 22K res in series with a 25K volume pot, for each channel. Can anyone explain what having this res there, does?
My thinking is that when the pot is fully wound round (ie. maximum volume, so the pot is out-of-circuit), the signal is still going through a 22K resistor - so I must be getting some signal attenuation.
The reason for my question is that I would like to achieve a bit more gain from my preamp - and I'm thinking that reducing the value of these resistors ( or removing them) would do this?
Thanks,
Andy
