Review: Works Perfectly - I use this to switch between 2 different sources - CD player output and TV audio output, to shared speakers. I was a bit skeptical from reading the negative reviews. But didn’t have any problem - no humming sound, the mute button actually works, the volume control nob works too, the switching works perfectly (even during “hot switching” when both sources are active). Pleasantly surprised. It was a good buy, solved my problem.

Works amazingly

### ⭐⭐⭐⭐ Not perfect but workable
*by S***Z on October 31, 2025*

Poor isolation- the input channels bleed into each other so you still hear both sources when you only want one. Seems to be because the ground is common and not switched as the other reviewer mentioned. Would have been otherwise great. edit- Adding 2 stars, realizing that switching grounds would make for a more expensive design beyond a DPDT switch, and has its own complications as far as timing. Instead, I added a ground loop isolator ( https://a.co/d/4Fv8bu2 ) on my "loudest" input and and together all is good.
