AKG 7801H00220 - AC12 12V/0.5A (Level VI) Power Supply with DC Lock Connector and EU/US/UK/AU Adapters

The AKG 7801H00220 is the original AC12 power supply for AKG wireless systems. It is a 12 V DC / 0.5 A (max. power 6 W) switching mode (SMPS) adapter with Level VI energy efficiency and a DC connector with locking ring ( DC Lock ) that prevents accidental disconnections. It includes plug adapters for Europe, USA, UK and Australia , making it easy to use on tour and internationally. It is the standard power supply for receivers and accessories of the WMS400/450/470 and WMS4000/4500 families, as well as for units such as the HUB4000Q and ASU4000 , guaranteeing a stable and silent power supply.

The output cable terminates in a 5.5 mm (OD) × 2.0 mm (ID) coaxial cable with locking thread , designed to mate with the threaded jack of AKG receivers. The input is universal (≈ 100–220 V~ , 50/60 Hz), so it does not require external power supplies in most countries. If you need an official replacement for your AKG system or a backup power supply for live performance, this is the recommended option due to its compatibility and reliability.
