AKG WMS40 Mini Instrumental Trådløst system ISM1: 863.1MHz

AKG WMS40 Mini Instrumental ISM1 — License-Free Wireless Freedom for Guitar and Bass

The AKG WMS40 Mini Instrumental ISM1 is a plug-and-play wireless instrument system created for guitarists and bassists eager to ditch cables without overcomplicating their gear. Utilizing the license-free 863.1 MHz ISM1 band, this model operates immediately across Europe with zero registration or fees. After opening the box, the PT40 Mini transmitter and SR40 Mini receiver can be paired in seconds, allowing musicians to get straight to performing.

What Sets This Wireless System Apart

At the heart of the system is HDAP (High Definition Audio Performance) technology, carefully engineered to deliver the instrument’s full frequency response from the input at the transmitter to the output at the receiver. The PT40 Mini pocket transmitter accepts both guitar and bass signals via its pro mini-XLR input, while the SR40 Mini receiver outputs a balanced 6.3 mm jack signal—ready for amps, mixers, or pedalboards with no added hum.

Who This Wireless System Is For

The AKG WMS40 Mini Instrumental ISM1 is the right fit for gigging guitarists, bassists, and keyboard players looking for a reliable wireless connection at a manageable price. Many worship leaders, pub musicians, and acoustic soloists value the long 30-hour battery life and fast setup.
