Beyerdynamic"s versatile TG I55C helix condenser microphone really demonstrates its strengths when used with instruments such as the violin, viola, recorder, dulcimer, and many others. It delivers extremely natural, true sound reproduction without coloration due to the proximity effect. The omnidirectional polar pattern ensures even sound regardless of how the capsule is positioned. The unique, innovative helix clamp enables quick and easy mounting without drilling holes or scratching the instrument. For wired operation at a phantom powering input, the optional CV 18 (sold separately) is necessary. Since 1924 Beyerdynamic has remained a German family owned company committed to continuous research and innovative developments for the audio market. All over the world, Beyerdynamic is known for the use of the latest technologies and a high quality standard. All Beyerdynamic products are made in Germany.
