One of the great references of the genre on stage or in the studio. Specially designed for multi-purpose use, this pair of 'matched cigar' static microphones delivers flawless reproduction of the entire audio spectrum, with exemplary clarity and fidelity. Stereo X/Y or overhead use. 22mm capsule, straddling the line between small and medium, for a high signal-to-noise ratio while retaining an extremely wide, linear bandwidth. A low-cut filter of 12dB/octave at 100Hz to attenuate any 'sub-bass' that may be undesirable in certain situations. duo A1S are incredibly effective on string, wind, and percussion instruments, and are often used on drum overheads, acoustic guitars, and pianos. As well as on choir recordings, orchestras and all types of ambience. More info here
