XLR dynamic microphones contain filters that help capture audio, eliminate background noise and deliver clear and professional audio. The microphones, used in both studio and non-studio settings, also come in a variety of sizes and styles. An XLR dynamic microphone can be connected to your computer and used in place of your computer's built-in microphone. The connection is made through your system's sound card/built-in microphone jack via an adapter or a pre-amp to process the audio signals.
