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

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.

You can use it either way, inputs can be outputs, and the output can be an input. I am using it as the latter. The mute button is very handy, and the knob to switch feels decent to use. Solid 9/10.Updated: Lasted just under 6 months, and it is now going on the fritz with the right side speaker. Disappointing, because it was a great little unit until now.

A fonctionné quelques mois,le côté gauche ne fonctionne plus,je les jeté au poubelle se soir ,vraiment cheap comme gadget

Piece of crap, buyers beware.

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.
