AKG WMS40 Mini2 Vocal Dual Trådløst sæt US45A: 660.7MHz + US45C: 662.3MHz

AKG WMS40 Mini2 Vocal Dual Wireless System — Plug-and-Play UHF Performance

The AKG WMS40 Mini2 Vocal Dual US45A/C is a comprehensive wireless microphone package tailored for singers, speakers, karaoke hosts, and small-venue performers requiring quick, reliable cable-free operation. Two HT40 Mini handheld transmitters connect to one SR40 Mini Dual receiver, letting both performers move freely while the audio remains stable. Because it arrives pre-configured on US45A and US45C frequencies, setup takes only seconds—no need for frequency coordination, scanning, or navigating menus.

Within each handheld transmitter lies a dynamic cardioid capsule engineered for clear vocals and excellent feedback rejection, ensuring voices cut through PA systems and karaoke rigs without remixing. Performers in schools, worship spaces, and mobile DJ events favor the WMS40 Mini2 Vocal Dual for its reliable, immediate plug-in operation.

Standout Features of the WMS40 Mini2 Vocal Dual

Rather than typical entry-level kits, this system offers an unusually long battery life and genuine dual-receiver operation, all in a compact housing. HT40 Mini transmitters run for more than 30 hours on a single AA battery—outlasting most alternatives that require 9V cells—while the SR40 Mini Dual receiver provides two balanced 1/4" jack outputs, so each microphone is mixed separately at the desk.

Wireless Performance — Frequency, Range, and Signal Quality

Reliable signal transmission is essential for live sound, and the design here maintains stability across small to mid-sized venues. Operating on UHF frequencies between 660 and 865 MHz, this model avoids crowded 2.4 GHz bands and typical Wi-Fi interference. With fixed frequencies, pairing is unnecessary—just power on the transmitter, and the receiver locks in immediately.

• Carrier Frequency Range: 660–865 MHz — UHF band for clean, license-friendly operation in most regions
• Modulation: FM — analog FM transmission for low-latency vocal reproduction
• This model delivers a full-range audio response from 40–20,000 Hz, preserving the warmth and detail of every voice.
• Signal-to-Noise Ratio: 105 dB(A) — quiet floor that keeps hiss out of the mix
• THD at 1 kHz: 0.8% — clean vocal transmission without audible distortion

Transmitter Design — Capsule, Battery, and Handling

Both transmitters rely on a dynamic cardioid capsule that resists unwanted off-axis sound—exactly what vocalists need when faced with stage monitors and audience noise. There is a single on/off switch with a dedicated mute position for efficient stage management, while the robust body is balanced to reduce wrist fatigue during long sets.

• Capsule Type: Dynamic, cardioid pattern — focused pickup that rejects stage bleed
• Power Source: Single 1.5 V AA battery per transmitter — no proprietary packs, easy worldwide replacement
• With battery life greater than 30 hours, you can cover multiple events on one cell.
• RF Output: Max. 10 mW — typical range of roughly 30 m line-of-sight in real venues

Receiver and Connectivity — Outputs, Power, and Build

The SR40 Mini Dual receiver serves as the system hub, featuring a clear front panel with indicators for power, RF lock, and audio clipping. Two balanced 1/4" jack outputs feed separate mixer channels, allowing each performer their own fader. The universal power supply, complete with EU, UK, and US adapters, ensures touring compatibility out of the box.

• Receiver: SR40 Mini Dual, fixed-frequency dual-channel — two independent mic channels in one unit
• Dual outputs mean you can assign each mic to its own mixer channel for custom control.
• Status LEDs: ON/OFF, RF OK, AF CLIP — instant visual feedback on signal health
• Power Supply: Switched-mode, 110–240 VAC with EU/UK/US adapters — worldwide compatibility out of the box
• System Weight: ~1.10 kg — light enough to throw in a gig bag

Who the WMS40 Mini2 Vocal Dual Is For

Vocalists, presenters, teachers, worship leaders, and event hosts who want two dependable wireless microphones—without complex pro touring gear—find a solution in this dual system. Schools and houses of worship value the AA battery convenience, plus the ability for two users to share one receiver without extra rack hardware. Bands and duos can set up in under a minute, covering long services or multi-act shows without interruption.

The kit includes everything required: receiver, two transmitters, universal power supply, and batteries. This makes it especially suitable for first-time wireless buyers looking for a name-brand dual system without complex menus or frequency coordination.
