The Boya BY-MP4 Audio Adapter is a simple yet functional two-channel audio adapter. Using the included 3.5 mm TRRS cable and the 3.5 mm TRS cable, the Boya BY-MP4 is easy to connect with a smartphone, DSLR, camcorder or PC. The Boya BY-MP4 Audio Adapter offers you an easy solution for using audio mixing and dual mic mounting. The audio adapter has three mounting shoes on which you can mount various accessories, such as microphones, wireless receivers, LED lighting and the like. This audio adapter can be used without batteries; the BY-MP4 works on the phantom power of the camera.

The Boya BY-MP4 could be used as follows: you connect a shotgun microphone (not supplied) to the stereo input, which you attach to the top door of the BY-MP4. Connect a lavalier microphone (not supplied) to both mono inputs. These can also be wireless microphones, where you can attach the receivers to the left and right hotshoe. You can switch between the sound of the shotgun microphone and the sound of the microphones with the stereo mono button. Since the sound of both mono channels is sent to the camera on a separate track, you can edit both separately in the editing.
