Provided is an apparatus and a method for coating objects and in particular containers with at least one first and one second coating station, wherein these coating stations each have at least one first coating electrode and one second coating electrode, and with a supply device for electrical supply of in each case at least one of the coating electrodes. The supply device has a high-frequency generator device for generating an a.c. voltage and/or voltage pulses as well as an a.c. voltage distribution device which distributes this a.c. voltage and/or the voltage pulses respectively to in each case at least one electrode of the first coating station and at least one electrode of the second coating station, wherein the a.c. voltage distribution device is suitable and intended for distributing the a.c. voltages and/or the voltage pulses with a time delay to the electrodes.
