Sonance SS4VC Speaker Selection Volume Control System Selector

hi I'm Karl with apt and this is the so Nance SS for speaker selector switch and what this allows you to do is hook up four pairs of speakers to it and you can turn on each pair individually by these buttons here on the front this does come with little labels so you can actually put a little label right on the front of the button here so it'll tell you which zone you're going to send music to so all you do to turn on the music in that particular zone is push the button in and then it's gonna send sound right to that particular pair of speakers on the back here you have your input and then you have outputs to four different zones of speakers this one also has a protection switch so with that turned on it's only going to send 50 watts to each channel with it turned off it can send 120 watts to each channel but you run the risk of blowing speakers if if the speaker's aren't powerful enough
