4-Way Stereo L/R Sound Channel Bi-Directional Audio Switcher, 1 in 4 Out or 4 in 1 Out, L/R Sound Channel Audio Switch Splitter RCA Stereo Switch Selector for DVD Stereo Speaker CD Player

This unit replaced its cousin that had the annoying hum (see my other review) and it seems to work perfectly. No hum or other problems. I still can't figure out why there are electronics in these things if all they do is switch channels. But it's a good little unit.

This little switch works as it should. Doesn't seem to degrade the sound quality. However, I'm not using it in a high-end system.

It works well for what its supposed to do, Solid RCA switch with smooth control, very compact, worth it for the price, but it does "pop" when switching between channels if your main amp is on.

Works as promised, switch feels high quality and looks great 👍

I have 3 audio sources and three separate sets of speakers. It did not add any noise to the audio signal and has created an effective method of switching between my audio sources. This device took less than 5 minutes to connect and worked right out of the box. No mods or fussing, just works.

I am sharing a turntable between two systems. A major problem whenever I turned up the volume up high, It sounded like my speaker had blown out. I replaced the RCA cable with a new one going to my McIntosh preamp to the switch. Had the same problem. I eliminated the switch going directly to preamp from turntable and the problem disappeared! Is there anyway I can do salvage my project?

All products worked perfectly and as advertised. Delivery was spot on. Stereo now works better than it ever did.

I bought this gadget for the sole purpose of having more than just one audio choice. With that, I hooked up again my tape and CD player and it does the job when switching from one audio source to another.
