Pyle 4-Zone Channel Speaker Switch Selector - Premium New & Improved Switch Box Hub, Distribution Box for Multi-Channel High Powered Stereo Amp A/B/C/D Switches, 4 Pairs Of Speakers, Black - PSS4

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

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.

Great product, good value

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'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.

Title: Extremely Disappointed - Avoid This Speaker SelectorRating: ⭐️I hate to be the bearer of bad news, but I must express my extreme disappointment with this speaker selector. I'm not one to leave negative reviews, but this product truly deserves it.The primary issue that left me utterly frustrated is the abysmal quality of the wire clips. They are so flimsy that they practically disintegrate in your hands or, in my case, break after a mere day of use. It's infuriating how poorly they hold the wires in place, making the entire functionality of the speaker selector practically useless.Additionally, the design flaw regarding the wire entrance only adds insult to injury. The opening is ridiculously thin, making it a struggle to fit in wires, especially if you have 12-gauge speakers like I do. I had to tediously trim down the wires just to make them fit, which is an inconvenience no one should have to endure.Save yourself the time, money, and frustration – steer clear of this speaker selector. It's a regrettable purchase that has left me questioning the quality control of the manufacturer. My recommendation: explore other options that won't leave you dealing with broken clips and the hassle of modifying your speaker wires to make them fit.Why do they have QC stickers????

Original speaker switch stopped working. This works better then the previous one, I forget the brand. Good for wired yard speakers to shut zones off.

The Pyle PSS4 is very easy to set up and use. The box is small enough to fit into a tight environment, but big enough to allow easy speaker connections and large, well-spaced buttons for selecting speakers. The protection circuitry reduces volume when enabled, and it is convenient to select or de-select this feature. I am only running two pairs of small speakers from the unit, off the A channel of my receiver, and never at high volume, so I have left the protection circuitry off. In that state, speaker volume is equivalent to the volume on the single pair of speakers that I run directly off the B channel. If your receiver puts out no more than 100 watts/channel (the maximum rating for this selector), then the Pyle PSS4 is a very cost-effective and nicely constructed solution.
