This adapter allows you to connect a standard microphone with a 3-pin XLR connector to the iPhone/iPad/iPod or other compatible device for quality recording. This adapter incorporates passive components which provide DC blocking/isolation between the microphone input for device protection, as well as, impedance matching components for allowing a wide variety of microphones and instruments to be used with the device. This adapter works with Dynamic microphones, wireless microphones and battery powered condenser microphones. This adapter will not work with microphones that require phantom power, unless you connect a phantom power supply inline with the microphone. Compatible with iOS and Android Phones.
