AKG WMS40 Mini2 Vocal Dual ISM2/3 — License-Free Wireless for Two Performers

The AKG WMS40 Mini2 Vocal Dual ISM2/3 is a dual-channel UHF wireless microphone system designed for singers, speakers, and event hosts who want a fast, no-fuss setup. The package bundles two HT40 Mini handheld transmitters with one SR40 Mini Dual receiver, all pre-tuned to the license-free ISM2/3 frequency band at 863–865 MHz. The system is the right choice for users who need two wireless mics running simultaneously without frequency coordination or a rack of outboard gear.

What Sets This Wireless System Apart

Built around AKG's plug-and-play philosophy, the dual receiver houses two independent channels in a single compact chassis, each with its own antenna, volume control, RF indicator, and clip limiter LED. The HT40 Mini transmitters pair a dynamic cardioid capsule with an ON/OFF/MUTE switch on the body, giving presenters and vocalists quick muting between songs or segments without leaving the stage.

Wireless Performance — Frequency Band and Range

The ISM2/3 band sits inside the 863–865 MHz UHF window that is license-free across most of Europe, so the system can be deployed at weddings, conferences, school events, and small gigs without prior registration. Each transmitter broadcasts at a maximum RF output of 10 mW, which is enough to maintain a stable link across typical room-sized venues while staying inside the regulatory power limits of the ISM band.

• System Type: UHF wireless — operates on the license-free 800 MHz ISM band
• Frequency Band: 863–865 MHz (ISM2/3) — no licence required for use in most European countries
• RF Output: 10 mW max — sufficient indoor range for halls, classrooms, and small stages

Audio Quality — Capsule and Bandwidth

The HT40 Mini transmitters use a dynamic cardioid capsule that focuses on the singer's voice and rejects ambient noise from the sides and rear, which is essential when working close to stage monitors or PA speakers. A wide audio bandwidth of 40 Hz to 20 kHz captures the full body of a vocal performance, while a signal-to-noise ratio of 105 dB(A) keeps the wireless link quiet between songs.

• Frequency Range: 40 Hz – 20 kHz — full-range vocal reproduction
• Polar Pattern: Cardioid (dynamic) — reduces feedback risk on loud stages
• Signal-to-Noise Ratio: 105 dB(A) — clean wireless transmission with minimal hiss

Power and Connectivity — Battery and Outputs

Each HT40 Mini transmitter runs on a single 1.5 V AA battery, and AKG rates the runtime at over 30 hours — a figure that translates into weeks of rehearsals and gigs between battery swaps. The SR40 Mini Dual receiver outputs each channel through its own balanced 1/4" TRS jack, so the system drops straight into a small mixer, a powered speaker, or a stage box without adapters.

• Battery Life: >30 hours per transmitter on one AA cell — low running cost for venues and schools
• Power Requirement: Single 1.5 V AA battery per transmitter — no rechargeable packs to manage
• Receiver Outputs: 2 × balanced 1/4" TRS jack — direct connection to mixers and PA inputs

Who the WMS40 Mini2 Vocal Dual Is For

The WMS40 Mini2 Vocal Dual ISM2/3 is the right choice for small-venue performers, house-of-worship teams, school AV staff, and corporate presenters who need two reliable wireless mics without the cost or complexity of a professional touring rig. Solo entertainers running a duo act, karaoke hosts, and auctioneers benefit from the dual-channel design, while the license-free ISM2/3 band removes the paperwork that comes with higher-power wireless systems. The 30-hour AA battery life makes it equally suited to mobile DJs and rental fleets that need gear that simply works every time it leaves the case.

AKG and the WMS40 Mini Wireless Family

AKG has built its reputation on studio and stage microphones used by engineers and musicians worldwide, and the WMS40 Mini series extends that heritage into entry-level wireless. The Mini Dual Vocal Set packages two of the line's HT40 Mini transmitters with the SR40 Mini Dual receiver, offering a coordinated two-mic solution that shares the same plug-and-play DNA as the rest of the WMS40 family.
