4 Way Audio mixer Stereo line levels control Box mini passive mixer (X41)

It works well. I have 2 computers, fire stick and iPad plugged into the same pc speakers. Now I can control the volume between them all. I would suggest using an inline ground loop they are cheap on amazon. The volume control is all at the top. meaning the 1st 3/4 of the dial are low then it gets really loud from 3/4 to full volume. would be nice to have a powered option but passive has been fine. some reviews says it buzzed when you touch the connection but that typical and who keeps wiggling the connections. once set its fine. I actually flush mounted my to my desk front like a mini rack. Eventually I'll router it into the actual wood.

I got this mixer to combine a few 3.5mm inputs into my soundbar without constantly switching cables, and it’s been working exactly as I hoped. Now I can mix audio from my computer, a Google TV, and a Bluetooth receiver all at once. It’s super convenient, and the best part is it doesn’t need any external power—just plug in the inputs, and you’re good to go.That said, I did have to pick up some ground loop isolators for the outbound line and one of the inputs. Not really the mixer’s fault—just one of those things when dealing with multiple devices and shared power sources. Thankfully, the isolators were cheap, and everything’s been running smoothly since.For the price, this little box does a great job. It’s simple, compact, and saves me from constantly fumbling with cables. If you want a low-hassle way to mix a few sources into one soundbar or speaker setup, this one’s worth checking out.

The unit uses resistors on each input to lower their intake power, meaning even if you have a single line connected it will not be as powerful as the original.I purchased it because I wanted my children to have sound from a tablet and music piano to play simultaneously, but the resistors make the sound too quiet. I likely will remove the resistors or change to a lower resistance.Spend a little more and get a different unit.

The unit was nice looking and seemed to be built well but the audio out jack was flakey.What I mean by that is when you plugged an audio cable into the jack the connection was intermittent. I tried four different cables and they all exhibited the same problem. I thought that something in the manufacturing process might have placed a coat of a nonconductive material on the contacts of the jacks. I tried plugging and unplugging the cables as well as spinning them while plugged in, but nothing worked.I returned the unit for a refund.

This mixer is your basic passive parallel mixer. Meaning all volume pots simultaneously effect overall volume, so all knobs turned down will lower volume, for example. My powered speakers have way more power than I need, so this thing works exactly as needed and expected :)

It's fine enough for the price. The build quality, for whatever reason, is great... honestly better than it really needs to be for a product like this. My big issue with this product is that, since its passive, you just aren't going to get much 'oomph' in terms of volume. And because of that, I think having the volume knobs at all is a bad design choice, as you loose even more volume going through those, even if turned up to max. It's fine enough for casual use, but I'd really encourage people using these for "real" audio applications to look around for something similar that is ACTIVE (that is, requires power) OR a passive version that does not have volume controls.

Used to combine a few desktops to one amp/speaker system.

Bought this volume mixer to manage my audio from multiple sources leading into my headphones. My headphones are nothing special just general decent quality headphones. I know what they sound like from a phone, ipod, and computer and when I plugged them into this sound mixer I noticed even at 100% volume from all sources and cranked on the mixer the volume level was substantially lower. I am unable to use this for my purpose I was looking for but for what I'm getting for the price I'm sure I could find another purpose for it in the future. The build quality is very nice and had no other issues besides the lowered volume.
