An AKG Wireless Solution Designed for Stage and Installation
The WMS 420 is part of AKG's HF/UHF system range designed to meet the needs of users seeking a reliable, easy-to-deploy set that is scalable enough to handle multiple simultaneous links. The pack presented here combines a fixed-frequency SR420 receiver and a HT420 handheld transmitter, a duo particularly appreciated when looking for a high-performance UHF wireless microphone without complicating operation.
This series also stands out for its "field" orientation: transport, setup/takedown, and compatibility with more advanced antenna accessories thanks to the detachable antennas. Depending on the application, the range is also available with bodypack transmitters (presenter, headset, instrument), facilitating uniformity of a microphone fleet within the same venue.
Who Is It For and What Are Its Uses?
This system is ideal if you are looking for a wireless handheld microphone for singing, speaking, or hosting: concerts on small to medium stages, multipurpose rooms, places of worship, educational institutions, associations, corporate events, bars with live music, DJs, or mobile performances. The supercardioid directivity of the D5 capsule helps maintain a stable and present voice even in environments with high stage sound levels.
For fixed installations, it is also well suited for sound control rooms seeking a durable solution: multi-channel operation per band, audio connectivity adapted to professional environments, and the rack-mount option allow the receiver to be neatly integrated into a rack or technical furniture.
