Small Form Factor To Fit Tight Miking Spots - Great Sound

Heil Sound's HEI-PR31BW (HEI-PR31BW) has all the benefits of Heil Sounds PR30, but with a smaller footprint, making it ideal for mounting to toms and for capturing cymbals from underneath, as well as from overhead. Developed in collaboration with FOH engineer Bob Workman (hence the 'BW' designation), the PR31BW has -40 dB of side and rear noise rejection with the best SPL tolerance available, and there's no worrying about overload. This versatile mic features shock mounting, screen mesh and foam popping filter. Beyond its percussion applications, this mic is great for guitar, brass mic, vocals, brass horns, saxophone, piano, and vocals/broadcasting.


  • 4" Tall
  • Great For Vocals, Guitar Cabinets, Brass Horns, Saxophone, And Piano
  • Will Even Fit Inside Leslie Speaker Cabinets, And More
  • 40 Hz - 18 KHz Frequency Response
  • 3 Pin XLR
