I have to provide an outdoor karaoke solution for a high end home. The karaoke controller will be in the remote AV rack and use the existing outdoor speakers and subwoofers. I have three Cat6, 3 RG-6 and one microphone cable from the rack to the remote location. I am thinking a wireless microphone with two remote antennas over the RG-6 and a karaoke unit that can be controlled with an iPad app. What do you guys recommend for a reliable solution?
