AKG MUP82 Make-Up Protectors for LC82 MD Omni MicroLite Mics 10-Pack

AKG MUP82: Keeping Cosmetics Out of an Omnidirectional MicroLite Capsule

The AKG MUP82 is a ten-pack of make-up protectors for the LC82 MD omnidirectional MicroLite microphone, slipped over the capsule housing during cosmetic application and removed before the microphone is used. AKG describes the procedure in one sentence, and the accessory does nothing more and nothing less than that. What makes it worth ordering deliberately is that the omnidirectional MicroLite capsule is the smallest in the range and the least forgiving of contamination, so the few minutes it spends in a make-up chair genuinely determine how long it keeps its published performance. Ten to a pack is the quantity that lets a make-up room treat protection as routine rather than as an exception.

Pressure Operation and What Contamination Does to It

An omnidirectional capsule is a pressure transducer: sound reaches the diaphragm through a single front port and the capsule responds to the instantaneous air pressure at that one point, which is why its output barely changes as the wearer turns their head. That single port is also the accessory's whole reason for existing, because anything that partially occludes it changes the acoustic impedance the diaphragm sees and dulls the response before anyone notices a fault. Foundation and powder are particularly effective at this, since pigment binds into the protective mesh and oils then hold dust in place on top of it. Given that the 82-series capsule measures only 0.14 in (3.6 mm) across, there is no cleaning procedure that reliably restores a contaminated one, so a disposable cover fitted at the right moment is the only practical answer.

The 82-Series Is Not Interchangeable With the 81-Series

Two protector part numbers exist for a real reason rather than as a catalogue convenience. Cardioid MicroLite models carry the digit pair 81 and use a physically larger capsule housing built around a rear acoustic path, while omnidirectional models carry 82 and use a smaller pressure-operated housing with no rear path at all. AKG therefore publishes the MUP82 specifically for the LC82 MD and the MUP81 specifically for the LC81 MD, and fitting the wrong one either refuses to seat or sits loose enough to let cosmetics past. Wardrobe and sound departments that stock both patterns in the same drawer are the ones most likely to grab the wrong pack, so labelling protector boxes by pattern rather than by colour is worth the two minutes it takes.

Rotating Body Microphones Across Two Casts

Musical theatre is where these protectors earn their place most obviously, because a body microphone in a long-running production is worn by different people at different performances and every one of them arrives from make-up. A wardrobe supervisor running a double-cast show can fit a protector before each call, pull it off at the half, and keep the same microphones sounding identical from the opening week to closing night. Broadcast studios use the same routine for a rotating panel of presenters and guests, and rental inventories fit them before a microphone goes out on hire so it comes back in the condition it left. Because the protector is never on the microphone during a performance, none of this involves any acoustic compromise at all.
