I require an omnidirectional mic element for a Shure handheld transmitter. The mic is used for audience questions and few people know how to speak into a directional mic.
NOTE: Not all Shure handheld transmitters have interchangeable mic elements.
The Shure VP68 wireless mic capsule, introduced in June 2011, is sold as the model RPW124. The VP68 audio pick-up pattern is omnidirectional ("all directions"), so the mic can be held upside down, or sideways, and the talker will still be heard. This is a useful attribute when the mic is spoken into by a person that typically does not use a mic, e.g., an audience member asking a question, a family member giving a wedding toast, or a citizen addressing the city council.
Other useful attributes of the VP68 omnidirectional mic capsule are:
1) Minimal wind noise when used outdoors.
2) Minimal handling noise as the user touches, bumps, or moves the mic.
3) Minimal "P" popping when the user speaks words beginning with "P", "B", or "T".
4) No proximity effect [excessive bass] when the mic is positioned close to the mouth.
These forgiving attributes are beneficial for the novice mic user, plus these attributes improve the intelligibility of the spoken word.
