AKG WMS40 Mini2 Instrumental Dual Sistema sem fios ISM2: 864.375MHz + ISM3: 864.85MHz

Cable-Free Wireless System for Guitar and Bass

Cut the cable without losing tone: this wireless rig pairs an SR40 Mini dual receiver with two PT40 Mini bodypack transmitters. A duo or multi-instrumentalist can roam the stage, rehearsal room, or home studio with full signal integrity. The AKG WMS40 Mini2 Instrumental Dual ISM2/3 is the right choice for working players who need a license-free wireless rig that sets up in seconds.

What Sets This Wireless System Apart

AKG's HDAP (High Definition Audio Performance) technology refines the wireless signal path for cleaner transients and tighter low-end response, which matters most when reproducing the dynamic range of a passive pickup. The dual-channel SR40 receiver runs two independent audio paths with separate 1/4\" jack outputs, so two instruments play at once without sharing a mixer channel. Switched-mode power supply includes US, UK, and EU plug adapters.

Wireless Specs and Power — Built for Daily Stage Use

The WMS40 Mini2 Instrumental Dual ISM2/3 operates on the ISM2/3 frequency band inside the license-free UHF range, so the system deploys in most countries without prior coordination. Audio bandwidth, signal-to-noise ratio, and battery runtime are tuned for the dynamic range of an electric guitar or bass pickup.

• System Type: UHF wireless, dual channel — license-free operation in the 864.375–864.85 MHz ISM2/3 band, no frequency coordination paperwork required.
• Audio Bandwidth: 40 Hz – 20 kHz — captures the full frequency range of a guitar or bass signal, from low B-string fundamentals to upper-harmonic sparkle.
• Battery runtime extends up to 30 hours on a single AA battery per transmitter, easily covering a full rehearsal week or several gigs before a change is required.
• Compact Tabletop Receiver — non-rackmount design fits on a pedalboard or beside a small combo amp, ideal for small stages.

Who This Wireless System Is Built For

Guitar and bass duos who need two independent channels from a single receiver unit will find this instrument a practical fit. It also works for a multi-instrumentalist switching between two instruments during a set, or for a teacher running simultaneous student-and-demo rigs. Players who want a compact wireless system that fits on a pedalboard or beside a small combo amp will appreciate the Mini form factor. The license-free ISM2/3 band makes it a sensible choice for traveling musicians.
