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.
