Universal Mounting System - long

  • 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® universal clip-on mount attaches securely to instrument bell 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

    With a 9" gooseneck and universal clip-on mount, the ATM350UL is perfect for musicians who like to position the mic farther away from the instrument’s bell or for those playing big-belled instruments like the tuba. The mount features strong, rubber-lined clamping jaws and a locking screw to securely fasten the mount to the bell of your instrument or other surface. The socket screw locks the gooseneck to the mount, giving you the flexibility to position the mic exactly where you want it and the confidence to play freely, knowing that the mic will stay in place, no matter how much you move about.
