THE CIMPLE CO 4-Way RCA Switcher Kit - 4-In/1-Out A/V Switch Box for Composite Video and Audio - A/B RCA Splitter and Selector Switch - Retro Game Console Switcher Box with Cable, Black

Works as expected.

Switching between my turntable and my tv audio into my EQ and power amp. Works perfectly. No noise.

Now-a-days, my audiophile endeavors (as compared to the past) have been confined to a desktop PC environment. Thus, I have to look for small components and speakers to fit where they may in this arrangement.I was using two DAC units (digital to analog converters) and had to switch back and forth by unplugging and plugging in the RCA inputs going to my powered speakers. Of course, this eventually became a hassle as I stopped, stood up and reached to the shelf that the DAC's were on.I had been eying various RCA switchers in the past - some very expensive, others inexpensive. My main concern was not experiencing signal loss or degradation. So I took a chance on purchasing this 2 port video/audio switcher (I am only using the audio inputs - not the video inputs). When it arrived, the construction quality is on par with what you'd expect in this price range. And to be honest, I wasn't expecting much - but I was totally (positively) surprised at this little baby.After connecting both DAC's and switching back and forth between the two, I could discern no difference or degradation in sound qualities (and I consider myself a critical listener). Additionally, I love the push buttons in the front of the unit that allows you to switch between units. This was very convenient, while the RCA cables from the DAC's were connected in the rear.It should also be noted that although this switcher has a compact signature (size), it's large enough to prevent cables (no matter how heavy) from moving the unit around. And for those of you who have tried the various very small mini switchers on the market, getting them to stay in one place after cables have been attached, can be tricky.So for what this is - meaning the ridiculous cheap price you pay for this device, and for what it does - I'm giving it 5 stars.

I bought the two port version of this. Of course I have no need for the composite video functionality (not in this century, anyway), and am using just the audio. I was a bit nervous about the audio only switchers that have volume knobs. I don't want the signal going through any more circuitry than necessary!I confirmed it works in 2-in, 1-out mode (which is how the jacks are labelled), but I am using it in 1-in, 2-out mode. (Note again that I am only using audio, I have no idea if 2-in, 1-out would work for composite video!)

Bought to create an additional Aux input for an older stereo receiver. Two inputs in - one output to the receiver. Fairly small. I would've gone 5 stars if it had been a toggle switch between the two inputs instead of the two push buttons. But does what i need it to do and it was pretty inexpensive
