AKG WMS40 Mini2 Vocal/Instrumental Dual Wireless system US45A: 660.7MHz + US45C: 662.3MHz

AKG WMS40 Mini2 Vocal/Instrumental Dual US45A/C — Plug-and-Play UHF Wireless

The AKG WMS40 Mini2 Vocal/Instrumental Dual US45A/C is a UHF wireless bundle built for musicians who need a vocal microphone and an instrument running wirelessly on the same stage. Inside the box, performers will find the SR40 Mini dual receiver, an HT40 Mini handheld transmitter, a PT40 Mini bodypack and an MKG L instrument cable — a genuine plug-and-play setup that requires no frequency scanning or channel coordination. AKG's HDAP (High Definition Audio Performance) technology shapes the audio, delivering crystal-clear sound right out of the package.

Standout Features

Two independent wireless channels live inside one compact SR40 Mini receiver — each with its own volume control and balanced output — which removes the need for a second rack unit on stage. The HT40 Mini handheld is fitted with a dynamic cardioid capsule behind a rugged metal grille, while the PT40 Mini bodypack accepts the bundled mini-XLR-to-jack cable for guitars, basses or any clip-on instrument pickup.

Technical Parameters — Wireless Performance, Audio and Power

Operating on fixed UHF frequencies 660.7 MHz (US45A) and 662.3 MHz (US45C), both transmitters broadcast the moment they are powered up. The 40 Hz – 20 kHz audio response covers vocals and acoustic or electric instruments with full-range detail, and a single AA battery keeps each transmitter running for up to 30 hours — a figure that translates into a full weekend of shows without a battery change.

• Carrier Frequency: UHF, US45A 660.7 MHz + US45C 662.3 MHz — fixed channels, no setup required
• Audio Frequency Response: 40 Hz – 20 kHz — full-range coverage for voice and instruments
• Each transmitter runs for up to 30 hours on a single AA cell, which is class-leading runtime in this price tier.
• Receiver Outputs: 2× balanced 6.3 mm TRS — feed two separate mixer channels from one receiver

Who Is It For

This set is the right choice for solo performers, duos, small bands, presenters and house-of-worship teams who need to free a vocalist and a guitarist from cable tethering on the same stage. Schools, community theaters and mobile DJs benefit especially from the dual-channel receiver, which halves the rack space needed compared with running two separate wireless systems.
