Abstract
This invention is a linear preamp with switchable and variable gains, for several switched input signal circuits, so that the output of the preamp can compensates either for differences in the input signal amplitudes or for different desired signal levels for different inputs. The variation in gain control position or level produces a nearly log change in gain, to conform better to human hearing. The preamp does so with a minimum of low- or micro-power components, allowing run times of hundreds to thousands of hours on small battery packs.
