Build an Audio Mixer Projects All About Circuits

Aug 11, 2015· The full output of the mixer circuit is Vout = -Rf(V1/R1 + V2/R2 + V3/R3 . . . + Vn/Rn). Thus, by making RF larger the gain can be increased. The other option is to make the resistor in the channel(s) smaller, but you are already using a potentiometer that can become very small, thus increasing the size of Rf is a better choice.

Muting Circuits For Audio

4 MOSFETs. Enhancement mode MOSFETs can be used for muting, but two are needed, connected in 'inverse series' to get around the issue of the internal body diode.They can work very well, but the need for two is a bit of a nuisance. The fact that they need a DC gate voltage to be turned on is a disadvantage, but it's all the greater because it has to be a floating supply.
