- No External Power No Noise 4 Way 1 in 4 Out or 4 in 1 Out Audio Sound selector RCA Female Stereo 4 Channel Splitter switcher Box Switching

Great option for expanding my rca inputs on my vintage amp. No noise at all.

This device does exactly what they claim. I have used to add input devices to my high end audio pre-amp which only had four inputs: tape (in/out), tuner, aux, turntable. By connecting this to the aux input on my pre-amp, I now have four auxiliary inputs. Yay!

Hums constantly and loudly.

I ordered this twice works as described no add noise, I think the reviewers that complain about it are using cheap cables and source's, I use with a passive pre amp alps 27 volume pot. And a high quality amplifier and it does not ad any noise in the signal path, very happy

This is an either or unit - it can only be used on one or another item but not more than one at a time. It will not work how I need it to. I wanted to play back a cd player into 2 separate receivers at the same time. But otherwise, it is ok.

Was hoping the large knob would be be better. However, was loose when first tested. Doesn't feel as great as I thought it would. But it works

I have a 4 port KVM switch for switching between computers that I am working on. All of the KVM switches I have tried that also have audio switching produce signal noise from passing through the switch. I have since tried separate 4 port audio switches, but they also have some signal noise during usage. This switch is the first and only 3.5mm audio switch box I have tried that does not produce ANY signal pass-through noise at all.

Excelente

Buen rendimiento y calidad
