WMS 420: A Range Designed for Installations and Mobile Performances
The AKG WMS 420 wireless microphone systems are designed to meet the needs of users alternating between mobile use (hosting, conferences, presentations) and fixed use (rooms, places of worship, institutions, equipped stages). The range is based on a flexible UHF solution capable of integrating into both single-channel configurations and multi-channel setups, with up to 8 compatible frequencies per frequency band.
A complete WMS 420 system revolves around the SR420 receiver paired optionally with a handheld transmitter HT420 or a bodypack transmitter PT420. In this "presenter" configuration, the PT420 bodypack transmitter is paired with the C417L lavalier microphone, a combination particularly suited for natural, discreet, and effective speech capture.
Who Is This System Ideal For, and What Are Its Uses?
This pack is tailored for situations where freedom of movement and voice clarity are paramount: conferences, training, presentations, ceremonies, corporate events, hosting, or stage interventions requiring a discreet microphone. The C417L lavalier microphone remains visually unobtrusive while maintaining close source capture, helping to preserve intelligible voice even when the speaker turns their head or moves.
Thanks to its multi-system logic (up to 8 compatible channels per band), the WMS 420 also targets organizations that need to equip multiple speakers: schools, multipurpose rooms, technical service providers, and fixed installations seeking a coherent and scalable solution.
