AKG WMS40 MINI Vocal Wireless set ISM2: 864.375MHz

AKG WMS40 Mini Vocal ISM2 — License-Free Wireless Vocal System

The AKG WMS40 Mini Vocal ISM2 is a single-channel UHF wireless microphone system designed for vocalists, DJs, MCs, and presenters who need reliable, plug-and-play performance straight out of the box. Operating on the 864.375 MHz ISM2 band, this wireless system is free of registration and licence fees throughout Europe, making it ideal for travelling performers and small venue operators. The package pairs an HT40 Mini handheld transmitter with a stationary non-diversity receiver, delivering crystal-clear vocal reproduction for speech and singing applications.

What Stands Out in This Wireless Mic

With AKG's HDAP (High Definition Audio Performance) technology, the capsule response is shaped for noticeably clearer vocals compared to typical entry-level wireless sets. No need to scan frequencies — simply power on both transmitter and receiver, and your link is ready in seconds thanks to the fixed-frequency ISM2 band. Performers gain immediate hands-on control via a slide-style on/off/mute switch right on the transmitter body, avoiding any complex menu navigation.

Wireless Performance and Capsule Specs

Inside this model, the technical core combines simplicity with the trusted audio quality AKG is known for. Off-axis sounds are rejected by the dynamic cardioid capsule, which is essential when monitors and PA speakers are positioned close by.

Who the WMS40 Mini Vocal ISM2 Is For

This model is a strong fit for DJs, MCs, karaoke hosts, worship leaders, and presenters in small venues who need a dependable wireless handheld microphone without licence paperwork or frequency coordination. Mobile entertainers can run multiple events back-to-back thanks to the 30-hour AA battery life. The dynamic cardioid capsule is built to control feedback on loud stages. By using a fixed-frequency ISM2 design, the system delivers plug-and-play simplicity without channel adjustment — a real-world solution for most entry-level and intermediate wireless users.
