AKG WMS40 Mini2 Vocal Set US25A/C - Dual UHF Wireless System with 2 HT40 Mini Handheld Microphones and SR40 Mini Dual Receiver (537.500 + 539.300 MHz)

The AKG WMS40 Mini2 Vocal Set US25A/C is a two-channel fixed UHF wireless vocal system combining two HT40 Mini handheld microphones ( cardioid dynamic capsule) with the SR40 Mini Dual receiver . This version operates on the paired frequencies US25A = 537.500 MHz and US25C = 539.300 MHz , ready to use without complex coordination. It stands out for its plug & play configuration and an extra-long autonomy of up to 30 hours per transmitter with only 1 AA battery . The receiver integrates two wireless sections in a single chassis with independent 6.3 mm jack outputs (one per channel) and LED signaling of POWER , RF OK and AF CLIP for quick control on live television.

The audio chain uses FM modulation with HDAP companding to maintain clarity and intelligibility in real-world applications, with a 40 Hz–20 kHz range suitable for presentations, education, worship, and small stages . A universal switching power supply (100–240 V) with country-specific adapters is included.
