I have a client looking to control or supply music from a main store to several satellite stores which consist of single zone background music applications. They don't want local control or input. My solution consisted of an elan piece over a commercial amp using Sirius or Pandora for source at each location. Was just curious if there a was a better commercial solution that I wasn't aware of.
One thing I have learned in this industry. It is easier to pull a wire than it is to push one.
