A WMS 420 Solution Designed for Stage, Installation, and Mobile Performances
The AKG WMS 420 series was developed to meet the needs of users alternating between fixed use (rooms, places of worship, schools, AV installations) and mobile use (performances, conferences, events). The concept is clear: a SR420 receiver paired with either a handheld transmitter HT420 or a bodypack transmitter PT420, to adapt the system to the type of microphone and application.
This " Headset " version emphasizes comfort and intelligibility thanks to the C555L, while the range also offers "presenter" configurations (lavalier mic) or "instrument" configurations (instrument cable). This keeps you within the same ecosystem, convenient when standardizing a wireless microphone fleet.
Who Is It For and What Are Its Uses?
This system is particularly suited to situations where speaking (or singing) hands-free is required: conferences, training, presentations, theater, sports coaching, as well as stage performances that require movement and clear diction. The headset microphone maintains a constant distance between the capsule and the mouth, which helps stabilize volume levels and improve comprehension even when the speaker moves.
Thanks to the PT420 bodypack transmitter format, you can place the unit on your belt or in a pocket, maintaining a discreet setup appreciated in event and corporate environments. In installations, the multi-channel logic (up to 8 compatible frequencies per band) facilitates deploying multiple systems in the same venue.
