Nicely finished, good price, does the job

My dad loved this one, because the amplifier he bought only had 2 inputs and with this one we were able to easily connect his cd player and tapes player to the amplifier. It's a great deal for the money, also it feels sturdy enough and it's easy to use, like plug and play. The way one can switch between inputs is convenient because the switchs are in the front.

This switch is an awesome addition to my home stereo system. I needed a method to physically connect my iphone or ipad to my stereo system. The inputs on the stereo system are RCA, and I had them all in use. So, I bought a Lightning/USB-C to RCA cable for my devices along with this switch and am now sharing the phono input on the stereo. This switch is a convenient small size, so it doesn't take up much space. It is well constructed of metal (steel or aluminum). The push button switches are totally mechanical and uses no electricity, so it doesn't need to be plugged in to an electrical outlet.

Works as expected. Using it to share a subwoofer between 3 amplifiers.

Works perfect. Great sound and looks pretty good on top of my sound system

I had just bought a new amplifier, which could accommodate a single auxiliary input feed. But I had more input devices than that and needed a neat way to wire them all into the amplifier and switch easily from one to another. This was just right.

I had been contemplating making a small switcher like this - probably a little simpler, actually - as there are few 1/8" TRS jack switchers out there at modest cost. But then I did another search on Amazon, and, lo and behold, this little jewel turns up!I'll start right off and note one minor item / gripe that is slightly different from the description: Those 1/8" / 3.5mm TRS jacks on the back are black, not "silver" color. This makes them hard to see in weak lighting situations, which are typical for some (and my) usage(s) this will see. In fact, I bought this item from this vendor and paid a bit more specifically because the 1/8" jacks were pictured as "silver". I may well mask them off and add carefully a little silver or white paint to their very outside ends. To this supplier, I would suggest going back to the original shiny plated metallic finish.A version of this with gold plated jacks would appeal to audiophiles and semi-pro users. Charge $25.00, hahaha.I popped the switcher open and construction looks good, but, the switches are definitely on the cheap side. (This from a person who many moons ago designed and built his own audio preamp with mercury wetted relays to handle the audio switching, so, my "complaint" is that it remains to be seen how this unit will hold up under semi-heavy use and time. On the flip side, better switches would cost more.)A semi-pro pro sound version would be interesting: Replace the RCA jacks with 1/4" jacks. (Things might get a little crowded.) A fully "pro sound" version would have to be larger, to accommodate XLR jacks. But at that point you likely have a nice little (or large!) mixer on hand anyway...Otherwise, all looks good, and versatility is great!It should not be hard to add small brackets to the left and right side for semi-permanent mounting or even wall mounting.As noted in the product info., the switcher can be "inverted" to provide a single input routable to any of 4 outputs. (I believe a version of this unit with labelling for such a usage is available -- seems like I saw it earlier.But, best of all, and not stated in the documentation or sales description is that each set of input (or output) jacks are in parallel with themselves. That is, for example, the input RCA jacks are in parallel with the input 1/8" / 3.5 mm jacks. And the output RCA jacks are in parallel with the output 1/8" / 3.5 mm jacks. This opens up all sorts of intriguing possibilities if your source can handle moderately low input impedances. That means the source has to have a little current capability (the old NE5532 / NE5534 IC audio chip with a 100 ohm resistor in series with its output will do famously). Plus, the source has to have a decent size coupling capacitor on its output, if you don't want attenuation of the really low, lows. Most any decent headphone output can handle this.NOW... you have a switching splitter, or maybe a "feedthrough switcher", or a "switching adapter (or maybe a splitting switcher?) One can take the signal at that RCA input (say, coming off your old CD player) and feed that signal UNSWITCHED, *out* via the 1/8" "input" jack to, say, your computer (provided your computer has a 1/8" line input), AND you have TWO switchable outputs of that signal available if desired @ the output jacks (the output RCA jack in parallel with the output 1/8" / 3.5 mm jack.3 more inputs to go. Or you can reverse the whole thing. Or if you never have any other use for , it's input jacks are sitting there as a cable extender / adapter.All ya' gotta do is keep it all straight in your head, once it's hooked up!(Yeah, at almost 70 y/o, such things are a consideration for me - heh.)Further crafty possibilities could be created if one wants to fully dis-assemble the unit and start interrupting circuit board traces, but that's beyond the purview of this review (and will certainly void your warranty!)Have fun!!Update: The outside diameter of the screws in the sides of the switcher measures 2.84 mm. A "Chinese" M3?

I bought this to replace an old Radio Shack switch that was at least 25 years old that had been dying for quite some time. Sound quality through in my Dad’s old school Bose speakers is back, sounds like when the setup was new!

I use an audio switcher in my home studio to route audio from two computers, and two Pro Tools Digi 003 audio interfaces. I switch back and forth between devices a lot, so I've gone through other audio switches over the years, most have had plastic bodies & switches and wear out over time.This particular swither has metal body with plastic mechanical switches & it is passive, meaning it requires no electricity or batteries to make it work. Because the witches are mechanical, they make a metallic noise when you engage them, no super loud, but not 100% silent either. The RCA inputs & outputs on the rear are nice & tight but not overly so.Several manufacturers sell this switcher, so I'm assuming they all come from the same factory in China and are rebadged for whatever company is selling them. Overall the construction is good, I'm not experiencing any noise or crossover, so I'm assuming the electronics are better than many other similar devices for sale here. Nothing fancy, and doesn't look as nice as the Sima switcher I had, but I blew through two of those in about 3 or 4 years, so they weren't as robust as they looked.

I was trying to find a box or adapter that would allow red and white audio to be divided to two other items (ie hearing aid box and soundbar) that are used simultaneously. This worked perfectly. The box is of quality product and is user friendly. Would highly recommend.

I really like this RCA switch box!Build quality is excellent - it has a fully metal shell and it has good quality paint in a matte-black finish so it resists showing fingerprints. Best of all, the switching mechanism is mechanical, not electronic so it should last for many, many years. There's even screws on the case so you can open it up and apply contact cleaner in 20 or so years, as required.The RCA jacks are all colour coded properly to coincide with left/right stereo audio, but you can use them for ANY RCA switching application you see fit to use up to 2 RCA jacks and/or a single 3.5mm plug per button. The spring loaded buttons have a very satisfying click and (of course) automatically deselect the previous button when you push your desired connection.They even have nice silicone feet applied to the bottom of this unit so it won't slide around your desktop.Recommended!

Getting heavily into mixing/mastering I have this switcher in my studio (in reverse function, plugging my audio interface output into the "output" RCA jacks on the back of the switcher) to select 4 different types of speakers and headphones, and this is a major helpful tool - I can select my normal studio monitors as button one, then the other 3 outputs are smaller and more mid-range focused multimedia style speakers or surround sound speakers, etc. You can also hook up the 3.5mm stereo aux cord into each channel in parallel with the rca's as well so really you have 8 outputs and 1 input with the reverse use. And for fun and experimentation you can hold two or more buttons at one time to hear multiple different outputs at one time. Thanks guys, I'm loving this!

I like that this is simple and does not require power. I just plug the RCA cables in and it works. My bookshelf amp has only 1 AUX input so being able to connect both my PC and bluetooth and my DAC is great. It's also very small so it doesn't add too much to the clutter.
