Xantech CB60 6 emitter connecting block

I got a Xantech CB60 6 emitter connecting block so I could send the IR signal to all of my components that needed it. In the owners manual it states that a power supply is not used if it is being used only as an emitter expander and goes on to state that power supplies can be damaged.
Has anyone tried a power supply? I do not get consistent results on the my VCR which is the 3rd device that is connected to the IR emitter connecting block. Sometimes it works, sometimes doesn't. Do I need a power supply if I intend on expanding to 4 emitters?
thanks,
