How the Audio Works

The baseband supports three microphone inputs and two earpiece outputs. The
microphone inputs are MIC1, MIC2, and MIC3:
• MIC1 input is used for the phone's internal microphone,
• MIC2 input is used for headsets (HDB-4),
• MIC3 input is used for the Universal Headset.
Every microphone input can have either a differential or single ended ac connection to
UEMEK circuit. In the Nokia 6235/6235i/6236i, the internal microphone MIC1 and
external microphone MIC2 for Pop-Part™ accessory detection are both differential.
However, the Universal Headset interface is single ended. The microphone signals from
different sources are connected to separate inputs at UEMEK. Inputs for the microphone
