The Microphone Pro is a powerful measuring equipment to perform room acoustical measurements. It includes a high quality condenser microphone, a USB soundcard and the cables which are necessary to connect the soundcard to your computer and your hifi system. The Microphone Pro kit can be used with every room acoustic software. For the most common one, the Room Equalizer Wizard (REW), we even provide a calibration file. Using this measurement system enables you to optimizes the placement of your speakers and your listening position and to determine which measures you should consider concerning your room acoustics. Imporant to add that the Microphone Pro will not work with the XTZ Room Analyzer 2 Pro software, as that is limited to the microphone in the Room Analyzer Pro kit.
