Installation

  1. Attach the wire hanger:
    • Snap the wire into the groove on the microphone body.
    • Guide the cable through the spiral at the end of the wire, beginning at the bottom and working toward the exit.
  2. Hang the microphone according to the guidelines for placement.
  3. Aim the microphone toward the sound source by holding the wire hanger in place and twisting the microphone body.
  4. If necessary, tie a strong transparent thread or fishing line to the loop at the end of the wire hanger and attach it to a ceiling anchor for additional stability.
  5. Connect the XLR cable to a mixer or P.A. system.

    Note: This microphone requires +48V phantom power to operate.

Microphone Placement and Use

  1. 3:1 Rule: If using multiple Shure Centraverse overhead microphones, the distance between the microphones should be three times greater than the distance between the microphone and the sound source.
  2. Choir Installations: Place the microphone in front of the choir, above their heads and aimed at the back row.
  3. Windscreen: Use the supplied snap-fit windscreen to eliminate wind noise and plosives. To install the windsreen, snap it into the first groove on the microphone head. To remove the windscreen, locate the gap in the ring and use your fingernail to pull the windscreen off from the right-hand side.
