Heil Sound RC 22

Heil Sound RC 22

The Heil RC 22 is a replacement microphone capsule for wireless transmitters and uses the same internal elements as the PR 22. The RC 22 gives you all the great mids and highs, great articulation, high rejection of side and rear noise via the large diaphragm, phasing plug placement, and the patent pending ISO BAND™ shock-mount prevents handling noise from getting in the way.
The RC 22 lets you upgrade your transmitter (most all popular brands*) to the PR 22 sound and reliability with wireless freedom. Let your ears be the judge, the RC 22 will provide all the proof you need. Turning your wireless transmitter into a world-class microphone is just a few turns of a screw away.
