Pyle4-Zone Speaker Switch Selector - Premium Distribution Box with A/B/C/D Switches for Multi-Channel High-Powered Stereo Amp - Supports 4 Pairs of Speakers - PSS4

My 26-year-old Sony AM/FM receiver died, and the comparable Sony replacement unit lacked a second set of wired speaker jacks ("B") like the old unit had. [FWIW, as far as I could tell after searching really hard, no current Sony receiver accommodates a second set or wired speakers, nor do they include an AM tuner...sigh...].This Pyle device provides that missing speaker function. I can now (again) listen to only "A" (along with the rest of the 5.2 options in the family room), or just "B" in the kitchen, or even "A" plus "B".To use the Pyle device, I ran four wires from the new receiver's main front L&R jacks into the input of the Pyle device, and connected the main front L&R speakers to the Pyle's output for switch "A" and connected the satellite speakers in the kitchen to the output for switch "B".Note: I did have some concern since all four speakers are 8Ω, and worried that having A &B engaged simultaneously might result in impedance mismatching; however, that seems not to be the case -- or at least, not to the point that causes any problem for the switch or the receiver's amp, both of which include "protection" functions.I would recommend this product.

cool product easy to use and set up. worked great.

Great

Exactly what I wanted to control 3 pairs of speakers easily.Only issue is minor..The instructions do not explain what the “protection” button actually does. As an electrician, I assume it just places a resister in series to keep the impedance up when playing multiple sets of speakers to prevent your amp from struggling. When pressed, the volume is lower even when just one pair is connected. When playing all three sets of speakers, even with protection button pushed, my amp still warmed up a bit. That tells me it isn’t putting them in series to maintain friendly impedance.Beyond my curiosity though, it seems to do the trick, and my amp still lives.

I have speakers in different areas of my shop, including some outside. I wanted to be able to kill the exterior speakers when it gets late, as to not be rude to the neighbors while I'm wrenching away at midnight to my tunes. This works just as it should so I can select any pair depending on which area I'm working in. Or have the whole place jamming inside and out.

Ordered 2 of these things, both were defective. 1st one, was visibly defective straight out of the box (one of the "flip connectors" was just freely flapping around. Upon receiving its replacement, 2 of the 4 connectors I tried failed (one after installing the wire, became freely moving; the other, though the flip "locked", it failed to hold the wire.) Inspecting the other connectors, their tension was very inconsistent, which to me indicates very poor quality. Another side note, although the company touts themselves as a "US company", the product was made in China. p.s. Tried contacting tech support & other than a canned "we got your message, will get back to you", I haven't heard anything for several days.

I have a Sonos Amp and two sets of passive speakers: a pair of Polk in the living room and a pair of Sonos Outdoor speakers in the patio. I wanted a way to separately control which of them is on.One option is to buy another Amp. That would work and would also give me a way to separately control them from the app. But it would cost a few hundred dollars.So I bought this instead (for $26) and it does the job too. The only downside is that I need to walk over and push a button when I want to toggle which speakers are on.My wires are 14 gauge and yeah it was a little hard to squeeze them through these connectors, but it worked eventually.

I'm actually using this switch with hard-to-drive headphones, so that on shutdown when the speaker amp caps discharge - my headphones don't release a loud "BRAP" that might be damaging.Reading the many reviews about the protection button being backwards - I took out my multimeter before installing and confirmed that when the button is pushed IN, 3 ohm's get added in series to whatever speakers (or headphones) are engaged. If the button is pushed OUT, then there's no additional load - the resistor is out of the speaker path.I was initially concerned that the switch added noise or killed some treble, but after A/B testing today I can confirm that there's no audio difference in my setup.I believe other folks' reviews that build quality may be shoddy - but I apparently got a good one, it works exactly as it should and adds nothing to the music. I'm quite happy with this purchase.
