3.5mm Aux + RCA L/R Audio Switch Box 4 in 1 Out Bidirectional, BolAAzuL Stereo Audio Switcher Selector 4X1 Passive a/b Analog Audio Selector No Power Need

Working well with rca phono plugs

It works like it should.

Using this unit to put the input of 4 HF receivers into one speaker system for comparison purposes.Works as intended. Only complaints are that the unit is light weight and needs to stabilized when the buttons are pushed and the buttons themselves don't always seat well.

I am using this switch to make a complex Harman Kardon AV Receiver, simple for audio only usage. The HK I have is built to provide AV surround sound to a tv with all the connections you could want for viewing, recording, and enhanced listening. I bought the HK at the flea mkt at a very low price and when I got it home, I was at a loss as to how I could connect my computer output speakers, turntable, CD, old cassette deck, and run everything through my equalizer. I wasn't sure it was possible but I purchased this switch, knowing that I might have to return it. The HK has three HDMI inputs, two wide-bandwidth HDTV-ready component video inputs, four S-video inputs, a front-panel input for video games, and an auxiliary input for portable media players. This myriad of components means there are multiple options displayed on the receiver menu and no sensible way to connect my equalizer. With my components hooked up to different jacks (without the equalizer) I found myself flipping through the choices displayed on the menu screen prior to connecting this switch. It was not a pleasant experience (I did not have a remote so had to do all the switching by guess). So I bought this inexpensive switch and connected my turntable to a preamp and connected that to the first audio in port on this switch, connected the CD to the 2nd audio in port, connected the computer to the 3rd audio in port, and connected the cassette to the 4th audio port. Next, I connected the equalizer to the audio out port and ran that to the CD port on the Harman Kardon. The sound is fantastic and with the push of a button I can switch from one component to other without dealing the complex menu of the HK.

Works like a dream! I had another brand & sound quality was driving me nuts--mono instead of stereo, switches had static & noise, etc. This brand works like a dream! Perfect stereo, no static. I'm a part time musician & sound quality makes a difference. This one, unless it breaks early, is clearly a winner!

I bought this so that I could switch from my iPhone music to my computer sound with the external speakers I use. The iPhone plugs into the 3.5MM stereo port of Switch 1 (I had to get a USB-C to 3.5mm plug) and my computer dock is plugged into Switch 2 using a 3.5mm headphone jack. The 3.5mm output from the unit goes into my external speakers by 3.5mm plug (each switch on the unit has both 3.5mm and RCA inputs, so you have flexibility).If I'm listening to music from my iPhone and In need to switch computer audio (to listen to a message or video, or get on a Zoom/Teams call, all I have to do is press Switch 2 to change over. Some of these boxes have volume controls and mute switches. While this does not have either, I can mute by pressing Switch 3 or 4 since I have no audio input into those switches.I have no buzz/hum from either source. That can vary based on the source and the cords. You could always add an in expensive ground loop device, but I have not had to do so.This unit does NOT require power and is lightweight. I plan to mount it under my new desk using industrial velcro so that it's out of the way (my office is moving this week into renovated space). It is very light.If you need a simple switch to go from one audio source to another, this should fit the bill.

Muy práctico si tienes varios equipos a conectar

Small and functional easy fo figure out just what I was looking for
