4. Microphone Header - JP7
JP7 is a 2-pin, 0.100" spaced header that provides a microphone input connection. This is the same connection provided by the MIC jack on the bracket. A signal present at JP7 is switched in only when there is no plug in the MIC jack. The microphone input will supply 2.5 VDC phantom power required by an Electret type condenser microphone. A dynamic microphone can also be used, although the phantom power will degrade the dynamic range of the microphone somewhat. This can be avoided by using an adapter with a DC blocking capacitor when using a dynamic mi- crophone.
