HI, You have at least 2 solutions: 1) to use only one of your stereo transceiver inputs (R or L and gnd), and 2) to short circuit your generator output to both inputs. Very probably you will face no problem if transceiver input impedances are at least 10Kohm, otherwise these may sink extracurrent from generator and load it (in such case you may need a buffer (stereo). You have to care the generator's voltage to not saturate input(s). Hopefuly it will work easily. Rgds, Augusto.
