2 line output combiner convert consumer equipment stereo signal to mono or combine audio signal from two different equipments to1 input.
I measured the max output of my microphone at 2 vpp on battery power and my tablet s max output was measured at 3 vpp.
This required a larger gain on my microphone than on my music input channel.
