Hi, I need to use a second set of speakers as second monitors. I have my Eris plugged into my AudioBox iOne and was wondering if I can use the headphone output to feed audio to some Edifiers? I am concerned that I will not damage the AudioBox by connecting powered speakers to a headphone jack. It may seem like a very naive question but I prefer to consult before I make a mistake. Another available option would be to connect the AudioBox monitor output to an external mixer (*********) and from there connect the Eris and the Edifiers. Thank you very much in advance
