AKG WMS420 Headworn Set Band A Professional Wireless Microphone System
The AKG WMS420 is a lightweight, reliable wireless system built for studio sessions, live recording, and remote capture work where hands-free microphone operation and consistent audio performance are critical. The C555L condenser headworn microphone sits comfortably behind the neck with the boom adjustable to either ear, while the compact PT420 bodypack transmitter clips discreetly to a belt or waistband. This is straightforward, professional-grade wireless audio that prioritizes clarity and mobility during recording and performance tracking.
System Architecture & Range
The SR420 stationary receiver operates in the 530.025–559.000 MHz Band A range with 30 MHz bandwidth, allowing up to eight channels to run simultaneously without interference. The system delivers approximately 30 meters of wireless range, making it suitable for multiroom recording setups, booth-to-control-room wireless talkback, overdub sessions, and location recording where cable runs are impractical or compromise session flexibility.
Audio Performance & Reliability
The C555L condenser element captures clean, intelligible audio with a Signal to Noise Ratio of 105 dB(A) and 0.8% total harmonic distortion at 1 kHz, ensuring transparent vocal reproduction for tracking, voiceovers, and interview capture. Frequency Modulation transmission and diversity antenna technology provide superior rejection of multipath reflections in challenging acoustic environments, while the noiseless mute switch, gain control, and LED indicator on the beltpack allow real-time monitoring and level management during takes.
