Pyle 4-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

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.

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.

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.

Great simple product works great

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 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.

I needed a very compact unit for a kitchen system to fit on a small shelf. I have three sets of speakers hooked up to the Pyle PSS4 and connected it to a Pyle Home PCA4 Mini 2x120 Watt Stereo Power Amplifier: NHT super zeros (86db/watt), and two pair of Parasound C-260 in wall speakers (88db/watt) via nice Kimber 16 gauge in-wall speaker wire that cost considerably more than the rest of the rig. The result is musically satisfying output to moderately loud levels.The PSS4 switcher unit is sonically almost transparent in this setup. I can hear a softening when all the speakers are engaged, probably as a result of the impedance change in the ganged load. With only one, the sonic difference is virtually undetectable. In operation each speaker is selected or deselected by depressing its button - which functions as a toggle. Press it in and the speaker is selected. Press it in again and it pops out, deselecting that speaker pair. In the rear the speaker and amp connections are made via small spring loaded tabs. You'll need pins or very thin wire to fit in those little holes. I used pins.FYI - the first PSS4 unit I ordered was defective. The sound was muffled dramatically. I returned it for my current unit promptly and it was like night and day - so be aware that quality might vary. All in all, this unit provides excellent value for the money.
