Retail Store Sound System with Drop In Ceiling Speaker and In-Wall Remote Volume Control

Hi, I'm Norm, I'm part of the A/V Design Group, and one of the questions we get asked a lot is like, what's involved in installing volume controls for speakers. So what we're going to do today is take, and we're gonna put in...just like the electrician did, the very first thing when he got on to the jobsite was he went through and nailed up all his boxes. Unlike electrical wiring, which is totally cool getting crunched up back in a box, speaker wiring, stuff like that, not a good idea. You want it so that the wiring can flow back in and just hang down, and it's loose, you can pull it back out, so when you're going to actually physically install this, one of the keys is that you want the low-voltage box, this, to be the same height off the floor. So what you do when you're measuring is have a tape measure here. So ideally these boxes are 48 inches off the floor. You measure to the bottom
