There is a big misunderstanding about the word "mixer".
When people coming from audio talk about a mixer, then
they only want an "adder".
This means the circuit adds the signals of two sources.
It can be done in the most simple way with just two
equal resistors as it's done in this circuit.
When we can neglect the source resistance of the audio
sources then the result is:
Vout=(V1+V2)/2
The FET in this schematics just acts as a buffer to get a low
output resistance. It could be replaced by any kind
of transistor or an opamp if some small circuit modifications
will be done.
