The AKG PSU 4000 is a central power supply system for AKG WMS 4000 series components. The unit is capable of powering up to three components simultaneously, eliminating excess cable and bulky power adapters. When used with the PS 4000 antenna distribution system, power is distributed to the connected receivers via the antenna cable. There are 3 DC power output connections located on the rear panel, DC outputs 2 and 3 are reserved for direct connection to components, without the use of a PS 4000 antenna distribution system. The PS 4000 power supply includes a 19" rack mount kit and DC power output cables.
