Without additional hardware such as preamps or external sound cards, it allows for professional studio-quality recordings directly on the computer thanks to its integrated USB interface. As expected from CAD Audio, the large diaphragm condenser microphone delivers a rich and detailed sound, ideal for vocals, voice-overs, or instruments. Its cardioid polar pattern minimizes background noise and isolates the sound source being recorded. The U49 is "Class compliant" and compatible with Windows and Mac OS operating systems, eliminating the need for driver installation. The integrated headphone output of the U49 has a power of 125 mW and allows for direct monitoring of the signals with adjustable volume. For creative moments, it features an adjustable built-in echo effect. Founded in 1931 as Astatic Corporation, the American brand from Ohio made microphone history early on and developed the D-104, a broadcast classic that has established itself as a standard in numerous broadcasting stations worldwide for many decades. Launched in 1988 as the ProAudio division of Astatic, CAD Audio thus looks back on 85 years of experience in manufacturing high-quality microphones and has particularly revolutionized the project studio sector of the late 80s and 90s with its Equitek series microphones.
