'Quotes' are easy. Click once on the 'quote' icon of the message you want, then when it arrives at the 'reply' box, 'cut' out any parts that you don't need using 'Edit'. Everything quoted should arrive in your 'reply' message box.
My studio is absolutely hum free, but not without some tweeks. Any guitar that gets near a computer or TV screen will hum. Avoid. As mentioned, phase-related dimmers ANYWHERE in the house will cause hum if they are on the same power leg (at the fuse box) as your studio line. Same with any motors; refrigerators, heating motors, flourencent ballasts, etc. Make sure that you're on the other AC leg. You might have to do some wire switching at the breaker box. AC wires in and of themselves won't create a magnetic field problem unless they cross an audio wire at a right angle, or unless they're carrying huge current. That's why Romex cable is acceptable. Keep AC and audio wires well seperated. Shielding the entire room is a good suggestion if the field is being generated outside of the studio, and if that's what it takes.. One final thought. Make sure the service has a real good 'earth' ground. Good luck with the 'sweet spot'.
