The first mixer that I got was dead on arrival. I reached out to the manufacturer, and they were more than happy to send a replacement once I sent a short video of the problem. The issue seems to have been with the mixer, not the power supply. The manufacturer responded within three business days.I’m no audiophile, but I have no issues with sound quality, and using this mixer actually eliminated buzzing that I’ve been having when no audio was playing. The product works as intended and is easy to use! It’s an all-metal chassis, front and back.The issue that I had with the broken mixer was that the power light was blinking, and the audio was not passing through the mixer. (The light is supposed to be constantly on.)

I choose this 4 chan stereo mixer to tie my 2 computers and and an old Alexa echo device to a single sound system in my home office.This particular mixer has both 1/8" and 1/4" stereo phone jacks for all 4 inputs and the output, making itvery convenient for connecting to the system using 1/8" plugs without needing any adapters.I was pleasantly surprised to not run into any issues after installing this thing - it just works as it should and allows full control over the sound sources and the relative levels going into the amplifier. No change in sound quality no hum or distortion. I feel lucky to have found something this inexpensive that works so well!In addition, it turned out to be possible to connect a USB dongle to the extra jack on the output for my BT headphones. Thanks for all the jacks, LZSIG.

Does exactly what I needed, with room to spare. It's very quiet, with no discernable pass-through noise. Pots are clean. Having a power switch is a bonus, being that other mini mixers I've owned were powered off by pulling the plug. :)I must have gotten the "new and improved" model, because I've experienced none of the issues some earlier purchasers mentioned.

I have gone thru 2 of these and both arrived dead. Same issue others reported, plug it in and turn it on and the pwr light lights up and goes out over and over, making a popping noise every second. Almost like a slow kick drum hit. The issue is not the mixer but the power supply, the 12v power supply is putting out low voltage so the mixer tries and powers on and then can't over and over. I tested both mixers with a 12v power supply from my synth and it worked fine. Actually a great little mixer if you want to keep buying them till you find a power supply that puts out the correct voltage or you have a spare 12v center positive power supply. I really liked the mixer, I might try a third but if I have to spend extra for another working 12v power supply then I might as well spend the little more on the 6 channel version. Just know if you buy this you'll need to go thru a few till you find one with a good power supply

Heed the other reviews here about the AC power supply being insufficient. I experienced the same flashing power light and thumping on the output that others have. Fortunately I'm the sort of geek who has a box full of old power supplies, so I connected one of those and the product now works superbly, with zero noise or distortion that I can detect.I'm deducting one star for the defective power unit, and another star for the vendor failing to fix this long standing problem with their product that has disappointed and inconvenienced many buyers.UPDATE: The vendor was super responsive and offered a refund. They appear to stand behind their product very well. I chose not to take the refund, as I have made the product work as described above. I'm adjusting my review from 3 to 4 stars to reflect this.

this mixer was cheap, well built, it is VERY quiet making almost zero noise, and has a decently powerful amp for the output. I used this mixer as my primary for multi device live lofi recordings for a little over a year. only after alot of use i began to notice the nobs i turned the most began to produce a fuzzy static while they were being turned. once i stop turning the sound stops but it didnt do that when it was new. i did use them alot on a daily basis so that may be part of it. if you need a clean mini mixer that is dirt cheap but built well you have found it.
