Wow, that's a neat little device. I have a rather unconventional and simple setup, but I wanted to improve the audio for an interview with a GoPro Hero 4 mounted on a Feiyu G4 handheld gimbal. That works great. I installed it on a Feiyu G4 with stock GoPro hardware. Then I attach a Shure VP83 LensHopper gun mic to the side of the self-powered hot shoe that plugs into the 3.5mm jack on one channel, and an Audio Technica lavalier mic with an XLR connector that Phantom power required on the other channel. Channel. Each is independently level controllable, ideal for post-production mixing. The two exits are great;
