Cubilux4-Channel 3.5mm Audio Mixer, Ultra-Low-Noise Mini Audio Mixer for Sub-Mixing, 1/8 TS/TRS Input, Stereo Switcher Suitable for Guitars, Bass, Keyboards

Very tiny but extremely solidly built, and low noise just as advertised. I wish I had thought of looking for something like this years ago. I use it to send three computers’ audio to one set of speakers. No more switching!

I use this as a submixer for my smaller 3.5mm audio connection devices (Teenage Engineering EP-133, Micromonsta 2, Roland Aira compact series, Korg Volcas), then send its output to my audio interface via stereo 3.5mm to dual 1/4" TS connections. It's perfect for that application. If I power it from one of my computer's USB ports it is a little noisy, but that's most likely a ground loop issue. But if I power it from a USB bank or a phone charger, it's perfectly quiet. This little dude is also much smaller than I expected, which is neither a pro or a con for my use, but if you want something tiny and portable, this is your buddy. My only minor complaint is that I wish the power connection was on the same side as the audio connections, as it would fit better into my studio that way. Overall, pretty hard to beat for the price.

Got it for my buddy and he says the sound is immaculate, and it was easy to setup and use. It was also small enough for him to carry around in his bag to connect to his laptop, so it’s quite portable. It’s a pretty good price for what it is.

Don't make the mistake I did.... I was powering this with a portable battery but I'm guessing it doesn't pull enough power for my battery to see it so my battery cut power. Then when I was trying to use this mixer it was putting out 1/4 of my devices original volume. But then I noticed there was no blue light indicating it didn't have power. I press the button on my portable battery pack and boom I've got full volume! I had to find a different way to power this but now it works great.

Pretty cool little mixer. I was looking for a way to connect 4 inputs to one output. I was looking for a way to switch between multiple inputs. not a mixer. It works well and it doesn't add any noise into the signal when the level is turned to the max position. I am not using multiple inputs(mixing) at the same time. Solid little device and the knobs turn smoothly and have a nice rotation resistance. I would recommend this.

I picked this up to get both Alexa and our TV to connect to a sound bar...without having to change inputs! It let me eliminate one remote from the pile. I was able to get my Fire Stick remote to control the soundbar, and ignore the TV volume, so it works perfect.Anyway, I have the mixer volume dials for both Alexa and the TV set to nearly maximum, and there's no electrical buzz or interference. This little guy really did the trick for me!

Sounds clean, looks great!NOTE: No the cool right angle flat usb connector pictured does not come with the product!

Added an unacceptable amount of noise. Returned.
