3 in 1 Out RCA Stereo Audio Source switcher Switch Signal selector Splitter schalter Connector Distributor Box

Works well to go from my turntable to cassette player. It has even gotten rid of a static "pop" I was having intermittently on the cassette player (have no idea why though). Looks a lot better than many of the cheap ones out there, and the knob (vs the switch) is a nice touch.

Works GREAT!...Fast shipping and works as described . The best I found so far.

Simple design. I like the interface and that it has a volume knob. You will need to turn the volume up on computer and speakers and then control volume from the unit. Otherwise, the sound will be too low. I like that the dial selector and not just a button that may fail. However, the big issue I have is that when I have more than one source cable plugged in, I get a buzz in the speakers. If I unplug one of the cables the buzz goes away. From research, I see that passive switchers have the issue. Two laptops plugged in cause a ground loop. Unplug the laptop and the buzz goes away. Also, it’s very simple just to plug and unplug the 3.5mm cable on one of the sources to relieve the buzz, but it kind of defeats the purpose of the device. That is still easier than swapping cables to speakers.

It was hard to find something like this, a simple switch to easily change between aux inputs and/or outputs. So at any time I could switch between speakers vs. headphones for the output, or desktop vs. laptop for the input. (Or switch both input AND output at the same time if desired.) 4 inputs and 4 outputs is more than I really need, but it provides insurance in case one of the jacks starts to fail someday in the future (if that happens, I could just reconnect my cable to a different, previously-unused jack instead). Its construction is minimalistic, and the inside is exposed so dust could theoretically get in there. But perhaps this utilitarian design is what makes it as affordable as $13, so I appreciate it.

-Flaky The button that switches between sources is completely unreliable. I have to press it many times to get the switch to select the B source. -Noisy I hear high frequency background noise that is well above any normal signal to noise ratio for modern audio equipment. I was able to suppress the low frequency 60 cycle hum by running an extra ground connection from my computer to the switch. (I have not dealt with the 60 cycle problem in decades. This is a solved problem.) Full disclosure: I bought this a year ago and do not expect a dialog or recompense from the vendor. The shortcomings I am experiencing are not a problem of storage. The problems are due to the poor quality of the product. I have not approached the manufacturer for a replacement.

I was hesitant buying this no-name splitter, as I have had bad experiences in the past with similarly cheap audio devices on Amazon. But this thing is doing its job, which is simply to route one of 3 stereo inputs to one stereo output. I am using it with two vintage cassette decks and an audiophile CD player and I can't hear any quality loss on my system after several A/B tests (I've got decent gear too including a Topping amp and Audioengine speakers). The splitter is passive, so there is no active signal from, for instance, a power supply or board capacitor, that would interfere with your analog signal. While it's certainly possible some of these units were made inconsistently, leading to the negative reviews, mine is fine, and it's also possible people are using low quality RCA cables or have inherently bad/defective RCA outs on their gear. Whatever the case may be, for the extremely low price, it's worth a purchase to see if it works in your audio system.

This thing does what it should do. Its cheap, and fills a need for something that isn't a typical use situation. However it does introduce some static/white noise which comes and goes. I have this connecting 2 desktop computers to one set of speakers, and I've found in certain games I can change the pitch of the buzz by moving my character around and looking at different surfaces with different amounts of in-game lighting. I assume this is because the switch isn't shielded, but it's not so terrible that I can't live with it. If you're using for a stereo system or home theater etc I'd look for another solution.

My only issue is that the labeling is upside down for my particular setup, but that's no biggie. The video included shows me cycling through all the inputs. Neat little device that's easy to set up, and has a unique look. I didn't test it with Bluetooth to 3.5mm, or USB-C to 3.5mm.

Utilisé pour ce à quoi il est destiné . Il faut bien placer le sélecteur au risque de se retrouver avec 2 entrées en même temps (ça ne m'est arrivé qu'une fois).

Mi capita spoesso di sentire dei miei utenti che mi chiedono come sdoppiare l'uscita del preamplificatore per pilotare du impianti differenti e qui la soluzione, questo commutatore, ha una bassa perdita in qualità e permette di commutare da un ingresso su due uscite, lo consiglio a chi ha il prealmplificatore che non è dotato di doppie uscite linea o a chi deve comunque splittare una uscita su due ingressi differenti magari per registrare.

Very good product

It does what it's supposed to (switch between inputs) and I really like the look of it. The knob has a nice feel. Just what I needed to connect multiple inputs into powered speakers. Recommended.

Couldn't be happier with the product. Simple to hookup and it works great!
