The JTS MA-XU is a brilliantly clever device that plugs in to any standard microphone and converts it into a USB microphone for direct to computer recording. It works with dynamic microphones and condenser microphones including those that require external phantom power as it has a built in switchable phantom power supply. But it doesn’t stop there ! Connect your headphones to it and there is a built in monitoring system allowing you to hear the microphone and playback audio. A versatile plug and play solution for easy computer recording.
