Product description

• VS Violin, Viola, and Mandolin Microphone The VS Violin, Viola, and Mandolin Microphone from AMT is a miniature cardioid, condenser microphone designed for use with violin, viola and mandolin. The entire microphone and mounting mechanism is designed to clamp securely to the body of the instrument without damage to its finish.The element itself is attached to a flexible gooseneck, allowing easy positioning at the sound board. The cardioid polar pattern effectively minimizes off-axis audio that causes noise and feedback. An external beltpack provides the output stage and power supply for the microphone. The beltpack also provides variable impedance for line level output and standard a XLR output connector. The VS is powered with external 11-52VDC phantom power or 9-volt battery.
  Miniature Element and Mounting System
