Maintain consistent instrument audio without the drag of a cable. The AKG Perception Wireless 45 Instrumental Set Band combines an SR45 stationary receiver, PT45 pocket transmitter, and MKG L instrument cable into a practical wireless package for live performance and installed AV environments. Frequency-agile operation helps reduce interference risk in crowded RF spaces, while the included 1 AA battery and 10-hour battery runtime support extended sessions with fewer interruptions. This set is designed for teams that need straightforward deployment and dependable signal handling rather than a stripped-down consumer solution. The bodypack format keeps the transmitter secure on the performer, and the stationary receiver fits naturally into rack-based or tabletop audio workflows. With the included universal power supply and region-ready accessories, it is ready for use across common production and presentation setups. For venues, houses of worship, rehearsal rooms, and corporate event teams, the value is in predictable operation and a complete out-of-box configuration. You get the core components needed to move from wired to wireless quickly, with the build quality and system design expected from AKG and Harman.
