I have a Pioneer VSX 40 AV receiver. There is no microphone input and I am trying to somehow integrate one with it. My wife likes to sing karaoke on youtube but do not have a mic she can use with it. I am running youtube through Apple TV 3 through HDMI on Video 1. The problem is, there is no way to connect a mic since HDMI is being used. I know the receiver is Bluetooth capable but not sure if a handheld Bluetooth mic (if even available since I haven't seen one) will work. I have a Magic Sing Karaoke mic that can plug to the Video 2 input in front of the receiver. But that's just it, HDMI Video 1 and Video 2 cannot work simultaneously. Any ideas how I can get a mic to work with my receiver would be greatly appreciated. Thanks in advance.
