I am running a very high tech sound system in an old theater that is only metering at 110v and drops to 108-106v when all my stuff is turned on.
Allmost all my gear will operate on 110v but I really need 120v for proper operation of my equipment.
The meter says its 240v but for some reason all our outlets meter at only 110v.
Why is this and how can I fix it?

Never mind!
Didn't realize that the place was wired with 110v plugs and not 120v plugs.
Switched them out and now its all good.

110v plugs and 120v plugs shouldn't matter.makes no since to me.
