Replacement mic capsule for hand-held wireless transmitters using the PR 22 element.

The Heil Sound RC 22 contains the dynamic element of the PR 22, producing much better articulation with high rejection from the sides and rear.

Heil replacement capsules are interchangeable with any of the screw-on type hand-held transmitters that receive a 31.3mm/pitch 1.0mm. Some hand-held transmitters have a .035 inch hexagonal-head set screw to secure the microphone capsule. If your transmitter has that, loosen the setscrew in the handle of the mic transmitter before attempting to unscrew the original capsule.

Holding the bottom of the transmitter simply unscrew the original capsule turning it counterclockwise. Carefully remove. The three conductor contact board disconnects the contacts. Avoid touching or damaging the gold plated contacts on the transmitter or the contact board. Screw your new Heil RC Capsule onto the transmitter handle and tighten.
