FET audio mixer circuit


Posted on Feb 6, 2014

This FET audio mixer is an example of FET`s versatility. FETs are originally designed for high frequency applications but they can be used for audio frequencies and in fact they perform excellently in this area. The number of inputs that can be connected to the circuit is unlimited as long as the R1 value is chosen according to this formula: R1 =
