Thank you for purchasing an AKG product. This Manual contains important instructions for setting up and
operating your equipment. Please take a few minutes to read the instructions below carefully before
operating the equipment. Please keep the Manual for future reference. Have fun and impress your audi-
ence!
The PSU 4000 is a power supply with three 12 V DC outputs for powering a WMS 4000 multichannel sys-
tem. The unit features a 1-U 19" case for rack mounting*.
The PSU 4000 replaces the AC adapters that come with the various WMS 4000 components and thus
greatly simplifies the setting up of multichannel wireless systems.
Check that the packaging contains all of the components listed above. Should anything be missing,
please contact your AKG dealer.
