AKG WMS40 Mini Dual Vocal Trådløst sæt US25B: 537.900MHz + US25D: 540.400MHz

Dual Wireless Microphone System for Vocals and Presentations

The AKG WMS40 Mini2 Vocal Dual US25BD is a dual-channel wireless microphone system designed for moments when two voices need to move freely across the stage. In this model, two HT40 Mini handheld transmitters work with a single SR40 Mini2 dual receiver, making it easy for duos—from singers and hosts to presenters or karaoke partners—to enjoy clear audio. Forget about scanning or licensing: fixed UHF frequencies at 537.9 + 540.4 MHz take the hassle out of setup—just power up and go. Cardioid dynamic capsules help keep unwanted noise and feedback at bay, keeping the focus on whoever holds the mic.

What Sets This Wireless Set Apart

Combining two transmitters into one compact receiver eliminates the need for multiple systems and saves space. Each HT40 Mini can keep running for up to 30 hours on a single AA battery. Traveling between countries is simple since the SR40 Mini2 receiver operates on mains voltages from 110–240 V and comes with interchangeable plug adapters. To make things even easier, the receiver’s front panel features a straightforward volume knob and combined RF/clipping LED for each channel, as well as a single ON/OFF button.
