AKG WMS40 Mini Instrumental Trådløst system US45C: 662.3MHz

AKG WMS40 Mini Instrumental Wireless System for Guitar and Bass

The AKG WMS40 Mini Instrumental US45C wireless system delivers cable-free performance for guitarists and bassists on small stages, in rehearsal rooms, and at club gigs. Operating on a fixed UHF frequency of 662.3 MHz, this set is purpose-built for players who want clean audio without frequency scanning. The AKG WMS40 Mini Instrumental US45C is the right choice for working musicians who need a plug-and-play wireless rig.

What Sets This Wireless System Apart

The PT40 Mini pocket transmitter uses a professional 3-pin mini XLR connector, accepting guitar, bass, headset, and instrument microphone levels without adapters. The compact desktop receiver is not rackmountable as standard, with an optional RMU40 mini PRO rack mount kit sold separately. The switched mode power supply ships with US, UK, and EU adapters for international touring, and a 30-hour AA battery life removes common pain points of budget wireless rigs.
