The Trantec LM–22 (MIC–SJ212–P–R) is a Lavalier/Lapel Microphone, designed for use with the S4.04-BTX or S4.10-BTX Beltpacks that form part of the S4.04L or S4.10L kits. This product is perfectly suited to pick up highly intelligible speech or vocals, and is probably one of the most discrete microphones on the market.

Its ability to withstand moisture penetration and cosmetics make it perfect for the theatre world. Not only suited to speech and vocal use, the microphone would be equally at home being used for instrument pick up.
