4.2 Microphone Input

Dynamic and condenser microphones or audio test equipment are connected to the PGA2505EVMV2 input through combo connector J3. The combo connector combines both a 3-pin female XLR and a 1/4-inch TRS jack for connecting to microphones and test signal sources. Both the XLR and TRS jacks are wired for a balanced input. Figure 4-2 illustrates the combo connector pin configuration for the PGA2505EVMV2.
