AKG WMS40 MINI Vocal Trådløst sæt US25B: 537.900MHz

AKG WMS40 Mini Vocal Set — Plug-and-Play Wireless on the US25B Band

The AKG WMS40 Mini Vocal Set US25B is a fixed-frequency wireless microphone system for singers, MCs, lecturers, and small-venue operators who need their mic working the moment it is switched on. Tuned to the US25B band at 537.900 MHz, it ships pre-paired with an HT40 Mini handheld transmitter and SR40 Mini receiver — no frequency scanning step. Plug in the universal switched-mode PSU, drop in the included AA battery, and the system is live in seconds.

Why This Set Stands Out in Its Class

Simplicity is the headline feature and the main point of the design. With no menus or scanning, this is a true plug-and-play rig even non-technical presenters can run. Equally unusual at this price tier is the 30-hour battery life from one AA cell — competing handheld sets typically deliver only 8–14 hours from the same battery type.

Key Specifications — Frequency, Capsule, Battery, Output

For working singers and presenters, the parameters that matter most are the operating band, the capsule type, and how long the transmitter survives between battery changes.

• Operating Band: US25B – 537.900 MHz — fixed frequency, license-free in many regions
• The HT40 Mini handheld transmitter ships with a dynamic cardioid capsule that isolates the singer's voice from stage noise, so the mic picks up the performer rather than the room
• Battery Life: Up to 30 hours from one AA cell — enough for a full weekend of bookings
• Power Supply: Switched-mode with EU/UK/US/AU adapters — one PSU works in any country
• Receiver Output: Balanced 1/4" (6.35 mm) TRS jack — plugs into any standard mixer or speaker

Built for Small Stages, Worship, and Mobile Hosts

This set suits solo vocalists, karaoke hosts, fitness instructors, MCs, and small-house-of-worship teams who need a dependable wireless rig at a non-pro price. It targets spaces where cables get in the way but multi-channel systems are overkill: small stages, clubs, places of worship, hotels, and gyms. A single volume knob on the front panel keeps sound-check short enough for hotel staff to run a karaoke night without calling an AV tech.
