My microphone requires 4v-9v. The device that I have iriver h120 has a 3v battery so I believe that if I don't use a battery box, the plug in play will give me 3v.
I have a battery box which supplies 1v. If I connect my mic to the battery box, which is then hooked up to my iriverh120... will my total voltage be 4v?
Does it combine it or will I only get 1v cause of the battery box?
