AKG WM82 Beige Wire-Mesh Caps for Omni MicroLite Mics 5-Pack

AKG WM82 Beige Wire-Mesh Caps: Protecting a Pressure-Operated MicroLite Capsule

The AKG WM82 beige 5-pack supplies five wire-mesh protection caps for the omnidirectional MicroLite microphones, protecting the membrane from wind and pop noise as well as dirt such as make-up or dust. AKG confirms these microphones can be used with or without the cap, so it is an optional component, and it is the layer that the W82 foam windscreen is designed to sit over. Beige suits the concealed positions where omnidirectional body microphones are most often placed, against light skin and fair hair. Five caps to a pack is the quantity that keeps a working complement of microphones complete.

Omnidirectional Capsule Geometry and What the Cap Must Not Do

An omnidirectional MicroLite capsule measures 0.14 in (3.6 mm) across and operates on pressure, which means sound reaches its diaphragm through a single front port and the capsule reports the instantaneous air pressure at that one point. Because there is no rear acoustic path to preserve, the cap's job is different from its cardioid counterpart: it must screen contamination and absorb impact while leaving that front port acoustically open and, crucially, without sitting hard against it. A rigid mesh at a fixed standoff achieves both, intercepting powder and airborne debris while presenting negligible obstruction to the sound field. Substituting a soft cover pressed onto the port would change the acoustic impedance the diaphragm sees and dull the response, which is precisely why the pattern-specific cap exists.

Beige Across Lecture Rooms, Ear-Hooks and Hairlines

Omnidirectional MicroLite microphones turn up wherever a talker moves their head a lot, because a pressure capsule barely changes output as the source angle changes. That puts them on ear-hook frames for lecturers and fitness instructors, at hairlines for musical theatre, and on lapels for panel and broadcast work, and beige is the finish that disappears at the first two of those positions on light skin and fair hair. A university lecture-capture team standardising on ear-hook microphones across twenty rooms will normally hold beige caps as the default and darker finishes for specific presenters, because most concealed mounts sit against the face. Matching the cap, the foam and the tape in the same finish is what makes the whole rig read as nothing rather than as three separate objects.

Hygiene Rotation Across a Roomful of Presenters

Where a theatre keeps one microphone with one performer for a whole run, a conference or training operation does the opposite and hands the same microphone to a new person every session. That rotation is the real argument for stocking caps by the pack, because a cap loaded with another person's make-up and dried perspiration is neither hygienic nor acoustically neutral, and swapping it takes seconds while cleaning a capsule is not a practical option. A corporate AV team supporting eight panellists in a day, a training centre running back-to-back classes and a house of worship handing a lapel microphone to a series of readers all operate on that cycle. Fresh caps between talkers, fresh W82 foam over the top where breath noise is an issue, and the microphone itself stays untouched.
