AKG WMS40 Mini Dual Vocal Set - Channels A/B
The WMS40 Mini brings wireless freedom to studio and live recording sessions with a compact, lightweight design that stays out of the way during takes. This dual-channel system lets you record two vocalists simultaneously, maintain a backup transmitter for uninterrupted sessions, or quickly switch between talent without stopping tape. The dynamic cardioid capsules capture articulate vocal performance with excellent off-axis rejection, making this set ideal for overdubs, multi-vocalist sessions, remote recording setups, and fast-turnaround productions where cable management or talent mobility matters.
Wireless Performance & Range
Operating at 10 mW RF transmission power, the system achieves a 20-meter line-of-sight range (65 ft) with reliable frequency options across US25A, US25B, US25C, and US25D channels. Each HT40 Mini transmitter runs for 30 hours on a single AA battery, delivering extended session time between battery swaps and straightforward power management for all-day recording sessions or touring productions.
Audio Quality & Signal Integrity
The system delivers a 105 dB(A) signal-to-noise ratio with 0.8% typical THD at 1 kHz, ensuring clean vocal transmission with a low noise floor that won't compromise mix clarity. An audio bandwidth of 30–20 kHz captures the full frequency spectrum of the human voice, while the SR40 receiver's balanced 1/4" jack outputs integrate seamlessly into audio interfaces, mixing consoles, and studio monitoring chains.

Frequently Asked Questions
What is included in the WMS40 Mini Dual Vocal Set?
The set includes two HT40 Mini handheld transmitters with dynamic cardioid capsules, one SR40 receiver with dual balanced 1/4" jack outputs, and a universal switched mode power supply. Microphone capsules and AA batteries are not included.
How long does the battery last, and what type does it need?
