DPA 4091 Omni-Directional Condenser Microphone Black

With 144 dB SPL handling, this microphone can meet just about any challenge including miking an electric guitar amp. It is also an excellent microphone for use with percussion instruments as well as wind and string instruments. Due to their remarkably linear frequency response in the 20 Hz to 20 kHz range, sound system engineers can also use these mics for sound system alignment, testing and tuning. The rugged and compact design features a 5.4 mm (.21 in) diameter pre-polarized condenser capsule in a tapered body measuring just 12 cm (4.76 in).
