Theoretically...

If you had a spare 4 channel mixer and 4 headsets that had seperate input/output lines could you wire all the mic's from the headsets into the mixer then put a 4-way splitter on the output to the mixer and put that into the input to the headsets to create an intercom/cans system?

If I understand you correctly, yes.
But you can't page and all the mics would be live.

you could put an On/Off switch in the line from the mics.

if you have that much spare cable laying around that's actually a pretty cheap solution (read:free or mostly). and as was said, just wire in a few on off switches

Yes, in theory it would work. However, the line output of the mixer is not designed to be loaded by four line input devices, let alone speakers. You'd need a headphone amp type device, and by that point you may as well buy an inexpensive intercom power supply and a few beltpacks. Or just get radio's (NOT GMRS/FRS, needs to be either MURS or licensed UHF business two-way; see my previous thread on the legalities of radio's for theatre use).

Mike's right, the answer here is used Motorola business radios with earpieces.

Actually, while I used to say that about FRS, I've done more recent research, and it IS legal to use them commercially, just with the same restrictions as on family use, and no special privelege. IE, if somebody else starts using the same channel, you have to either suck it up or move; you can't say, "We're using this for business, find another channel," or anything else to try to get the newcomers to move. It's an open band, and must be kept as such.

Well, I stand corrected. I will point out that one must be careful when using dual FRS/GMRS radio's, through, to make sure one uses ONLY the FRS channels and not the GMRS channels (to use these channels one must have a license). Additionally, range and reliability will probably suffer due to the technical limitations of the FRS. That said, if it works for you, it works for you, end of story.

Mike, a GMRS licence is only about $75 US.
