installing an ARC system

It is not clear to me what you mean. Do you mean ARC=Anthem Room Correction or Automatic Room Correction or Audio Research Corporation? There are several other meanings for that abbreviation.

If you mean the first of these, it is available only in Anthem prepros or in Paradigm subwoofers. If you mean the second (or third) of these, you can purchase such devices (or software) and use them with almost any system if it has suitable connections.

disregard my comments - I was thinking ARC stood for Audio Research Corp. duh! sorry.

Kal has a bug for acronyms that I think is misleading or a least over limiting. For me the more general acoustic room correction is what I mean when I write ARC. I doubt Anthem has a copywrite on the acronym ARC.

My understanding is that there are stand-alone ARC systems, but I suspect most require a digitized signal, and that's a killer for those of us who use analog sources.

I don't have a bug for anything except clear meaning.

The only decent all-analog EQ (and not automatic) is the Rives Audio Parcel. All others are digital with analog or digital in/out.

Thanks for the tip about Rives, Kal. Do you mean by not automatic that it is an multi-band equalizer that displays a spectrum and requires the user to set band levels manually?
