Here's another view of the main air studio showing the turn tables (remember records?), the audio console, and the spiffy microphone holder-upper I made from fishing line and some lead sinkers.

Don't want vibrations transferred from the floor to the turn table? Easy - just cut a hole through the floor, make the turn table pedestal tall enough to sit on the foundation, and then fill it with 500 pounds of gravel. I guarantee the record won't skip when someone walks in the room.
