Piano Mounting System

  • Low-profile design for minimum visibility.
  • Crisp, clear, well-balanced microphone response, even at high SPLs
  • Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source
  • UniMount® magnetic piano mount attaches securely to the frame or other metal part of the piano, and provides excellent shock resistance for the microphone
  • Rugged UniMount® 9" gooseneck rigidly holds its shape, keeping microphone accurately positioned even during aggressive play
  • In-line power module is equipped with a switchable 80 Hz high-pass filter to control undesired ambient noise
  • Interchangeable elements available for hypercardioid and omnidirectional polar patterns
  • Included violin mount with hook-and-loop fastener provides an additional mounting option

    This ATM350PL system unique magnetic mount attaches to the piano’s cast iron frame or other metal part, allowing you to easily position the mic exactly where you want it. Whether set up vertically or horizontally, the mount stays where it is placed, but can also be repositioned with ease. Like the mounts in other ATM350a systems, the piano mount includes a screw to lock its 9" gooseneck into the mounting socket, and its base is lined with felt to prevent damage to the instrument.
