JBL VMA1120 Commercial/Restaurant 120W 70v Amplifier+(6) JBL White 6.5" Speakers

hello i'm rob with Crutchfield's commercial and pro idea team and today we're going to talk about parallel wiring in your commercial 70 volt audio system for this demonstration we're going to be looking at the Atlas SM 52 speakers a pair of the Atlas a T 100 D wall-mountable of volume controls the Atlas a 50 commercial amplifier and I've gone ahead and pre-cut some speaker wire for us to use in our demonstrations so first thing I want to do is talk about the concept of parallel wiring parallel just means that the same connectors are being used across multiple units and by that I mean that when we trace the common the ground line it's the same terminal on every piece of equipment that we're using whether it's speakers whether it's the volume controls or any combination of those so there's two sort of concepts home running which is going from a speaker directly back to the amp the source
