Monoprice SSVC-4.1 Single Input 4-Channel Speaker Selector with Volume Control, Impedance Protection, Individual Zone On/Off Buttons, Black, Model Number: 138159

Muy buenO

Have a patio/Deck area that that I needed three sets of speakers and a subwoofer wired into a new Sonos amp. With three sets of speakers, I was a bit hesitant to wire them up to the Amp. But with the impedance matching of this switch, it works great. I can cut on or off any set of speakers that I want, and I have the Sub on its own channel. I can also have one set of speakers playing louder than the others with the volume control. This thing really solved a lot of issues that I was trying to work through. Been working for about 4 months with no issues at all. Would definitely buy again and really wish that I had found it a bit sooner.

I have a patio that has two pairs of speakers spread apart almost thirty feet. After more than 19 years I've never been satisfied with the speaker volume control. The amp can control balance on each stereo pair but there's no fade like our cars have so I've aways heard one set as louder than the other and that changes every time I change position.I wired this unit up with one speaker per zone so I now have an individual volume control for each speaker.This unit was designed to individually control up to four pairs of stereo speakers so I'm very pleased it can handle indivuals too. The only reason I didn't give it five stars is because I save the fifth for longevity so great results for one afternoon isn't enough.

I bought this to replace a 24 yr old solution from another maker that was worn out. I carefully researched the options and reviews and picked the Monoprice. I’m glad I did. It was easy to install, though any such installation involves many wires in tight places. It took 14G wire easily. It works much better than what it replaced ever did. Having volume controls to each speaker is a plus: one speaker needs a boost because it is much further from the source than the rest.

My amplifier feeds 3 separate speaker systems in the house. One was always too loud but now I can balance them out. Great product

Solid construction. I like it has weight to it.The back green bits come off to make it easier to insert the audio cables. It's a passive device so no power requiredVolume control per zone was something important I required and this deliveredWorth the buy if you're on the fence

It seems to work just as described. It was definitely worth the extra money to get the volume control and individual speakers. That way I could compare different speakers without being influenced by the fact that some of them would be louder.

Left side of channel 2 stopped working after a few days. I swapped the speakers going to this channel and the problem followed the channel, so I know it's this box that is not working. I didn't keep the original packaging (who has room to keep the original packaging for everything they buy), so I can't return it for a refund or replacement. DON'T BUY THIS PRODUCT!
