Review: Top quality, full function, 3-channel audio mixer for a great low price! - The sound management quality was excellent... simple to operate... and, all controls (gain for each of the three channels and the master volume control) function with great smoothness and linearity! Two quality connecting cables are included— one for power access, the other for audio interconnection. The unit operates on a pair of AAA batteries (included), or via the use of the enclosed USB power cable. Additionally there are two front panel audio output jacks one for headphones, the other for direct connection to an external amplifying audio device. A 3-position slide switch provides a power-off option, an internal battery power source option, or a USB external power feed. A very bright colorful (2 colors) led illuminates to show which power source is in operation. Also, the packaging is first class and the large printed instruction sheet is among the best I’ve ever seen! I use it for my amateur radio station multi-devices audio integration control. It works very well and it is totally free of any 60 Hz hum. I would recognize that the most common use for this mixer is to provide merged audio mixing for up to three devices (I.e. tablets, I-pods, radios, etc.).
Review: Good audio mixer with some issues - First off to start, I was looking for a small temporary mixer between a phone and a computer or 2 computers into headphones. This product was just the one that I found that would fit my temporary needs. There is problems that I ran into but since it was the only minor issues that you can avoid I kept it and just went around the issues. Pros: -mix up to 3 devices with 2 outputs -headphone output -speaker stereo output -4 knobs to control 3 inputs and master output -USB powered so its really portable -smol c: Cons: -slight static noise -after 50% there is distortion if there is a lot of bass coming from one of the inputs -anything past 75% knob turn it sounds just straight up bad -instant noise reduction that is about 25% -this will not drive high end headphones.... -really heavy bass will get it distorted instantly Workarounds: -put all input devices on max volume -at most keep any of the 3 inputs at 50% -have the master knob put up all the way at 100% -add a DAC after the output for headphones -use a clean power source that is not connected to audio usb port that would be on a motherboard (USB 2/0 or 3.0) -have good cables for the inputs/outputs What I wish was better or had: -be able to have any audio go past 50% without distortion -provide another cable Overall I like the device, it gets me around my issue but the device isn't perfect. I will be keeping it and be using it at for now until I move and get a bigger mixer like the GoXlr, Behringer 502, 802 or 1204.

## Questions & Answers

**Q: Is it possible to be a microphone as one of the input sources?**
A: Dear Chanwoong Park,

Thank you so much for inquiring.

The Just  Mixer S do not provide condenser mic.
Because the Loop Mixer do not provide phantom or plug-in power for microphone. Regular mics that can be connected directly to the microphone jacks of PCs will work fine, but condenser mics and other mics requiring additional power source may not work. As below link for reference.
Dynamic Microphone

XLR to 3.5mm

So we suggest that you can use Dynamic Microphone and connect XLR to 3.5mm adapter.
On the other hand, you can use AVL606 Microphone which has provided power.

Besides , we have a microphone mixer of Just Mic 4 and Just Mixer M , Loop Mixer 8 for mics Mixer for reference.

Please let me know if you have further questions or comments.

Thank you again.Have a good day.

**Q: Is this trrs?**
A: All TRS.

**Q: Does the headphone jack cut off the line out when a cable is inserted? If so, how would I rig up an external female plug to be the "mute switch"?**
A: Dear Judas Ghost,

Thanks for contacting us.
Because the Just Mixer S of headphones and the output are on the same line, if you plugging in the headphones does not cut off the output line.

If there is any question or comments,please feel free to contact at infor@makerhart.com

Thank you. Have a great day.

### ⭐⭐⭐⭐⭐ Works Perfectly as a LOW audio Booster!
*by A***N on May 13, 2025*

You shouldnt expect too much from a mixer this small. The levels are a bit sensitive but it works perfectly for what I use mine for. I have a cheap video projector that my wife bought me. I keep it on my nightstand and project my nightly television time onto the ceiling. I use a small Bluetooth speaker for the sound and it's amazing. The problem with the speaker I'm using is this: There is a built-in noise filter or compression in the aux input. When certain movies grow quiet the sound cuts out. It's very annoying. SO, I take this little MIXER and use it to boost the horribly low audio signal from my projector and now I have no low audio cut offs. Also it has USB C power OR battery. Problem solved. So far 5 stars. In fact, I want another one.
