The Opus 53 is a condenser microphone consisting of a lightweight, but rugged, carbon fiber reinforced composite casing. Its small and short design allows flexible and unobtrusive positioning. The frequency response of 30 - 20,000 Hz has been optimized for universal miking of instruments. In particular, it is suitable for miking drums such as snare or hi-hat taking advantage of the tight cardioid polar pattern. But it is also a great microphone for miking brass and woodwind instruments as well as guitars and other string instruments.
