AKG WMS40 Mini2 Dual Vocal Set ISM2/ISM3 - UHF Wireless System with 2 Handheld Microphones and SR40 Mini2 Receiver

AKG WMS40 Mini2 Dual Vocal Set ISM2/ISM3 - UHF Wireless System with 2 Handheld Microphones and SR40 Mini2 Receiver

The AKG WMS40 Mini2 Dual Vocal Set ISM2/ISM3 is a plug&play dual-channel UHF wireless vocal system that combines an SR40 Mini2 Dual receiver with two HT40 Mini handheld microphones with a dynamic cardioid pattern. It operates on fixed, licensed frequencies freely available in Europe within the ISM band: ISM2 (864.375 MHz) and ISM3 (864.850 MHz) , allowing simultaneous use of both channels without programming or channel scanning. AKG’s HDAP electronics deliver clear, stable audio with a 40 Hz to 20 kHz response and a typical THD of 0.8% . Each transmitter operates for up to 30 hours on a single AA battery, and the receiver offers two independent balanced 1/4 ” (6.3 mm) jack outputs with per-channel volume control and status LED indicators (power, RF OK, audio clip). Supplied with 110–240 V universal power supply and EU/UK/US adapters, ready to integrate into venues, events and rentals.

Main features

• Dual UHF channel with fixed frequencies ISM2 (864.375 MHz) and ISM3 (864.850 MHz), free of registration and fees in the EU.
• 2× HT40 Mini dynamic cardioid microphones with On/Off/Mute switch and metal grille.
• SR40 Mini2 Dual receiver with volume per channel , two balanced 6.3 mm jack outputs and LED indicators (Power, RF OK, AF Clip).
• Wideband audio : 40 Hz–20 kHz; typical distortion 0.8% @1 kHz; FM modulation with built-in compander.
• Outstanding autonomy : up to 30 h per transmitter with 1×AA.
• Transmitter RF power : approx. 10 mW (typical max).
• Typical line-of-sight range : ≈20 m .
• Non-diversity design for easy deployment and maintenance.
• 110–240 V switching power supply with EU/UK/US adapters included.

Product benefits

• Ready to use : Two preset channels (ISM2/ISM3) that avoid frequency conflicts and speed up assembly.
• More controlled vocals : Cardioid capsules prioritize the front signal and help reduce feedback on small stages.
• Low operating cost : Up to 30 hours with a single AA per mic minimizes battery changes during long events.
• Easy integration : Independent balanced outputs per channel for direct connection to mixers or powered speakers.
• Clear monitoring : LEDs per channel (RF OK/AF Clip) and volume control allow for quick adjustments on the fly.

Use cases

• Corporate events , education, and presentations where two independent voices are required.
• Rental and mobile sound for hotels, places of worship, gyms, and small/medium-sized venues.
• DJs/entertainment and bars that need a stable, plug&play dual solution.

Frequently Asked Questions

• Can I use multiple systems at once? With the WMS40 Mini range, up to three simultaneous systems are recommended with adequate frequency separation.
• Does it have a mixed output? The SR40 Mini2 Dual offers two independent balanced outputs (one per channel) via a 6.3 mm jack.
• Is it legal in the EU? ISM2 and ISM3 carriers (863–865 MHz) are freely available in Europe; check the regulations if you operate outside the EU.
