Product Overview

The Williams AV MIC 090 is a mini omnidirectional lapel clip microphone for hands-free speech pickup with Williams AV assistive listening transmitters. Its omnidirectional electret condenser capsule maintains consistent level even as the wearer turns their head, making it forgiving for presenters, docents, and instructors who move while they talk. With a full 20 Hz 18 kHz frequency response and a weight of just 0.05 lbs, this mini lavalier microphone delivers natural speech to FM assistive listening receivers while remaining nearly invisible on the wearer. The right-angle 3.5 mm plug connects directly to the PPA T27 and PPA T46 transmitters.

Product Description

Omnidirectional lavaliers are the standard choice when wearer movement is unpredictable the capsule picks up evenly from all directions, so head turns and clothing position changes don’t cause level drops. The MIC 090 applies that principle in a miniature housing suited for personal FM systems, tour guide deployments, and classroom assistive listening where the talker wears a body-pack transmitter.

The 39-inch cord terminates in a right-angle 3.5 mm mono plug that reduces strain on the transmitter jack when the body pack is worn on a belt. Williams AV specifies the MIC 090 for use with the PPA T27 and PPA T46 transmitters, keeping the signal chain vendor-matched from capsule to receiver. With a 79 dB dynamic range and 63 dB signal-to-noise ratio, the capsule reproduces conversational speech cleanly without external preamplification.

Wear parts are field-replaceable: the foam windscreen is the Williams AV WND 006 and the lapel clip is the Williams AV CLP 090, so the microphone can stay in daily service for years. Find compatible transmitters and the complete accessory line in the Williams AV collection at Creation Networks.
