Maker hart JUST Mixer S Portable 3 Channels Stereo IN Mini Audio Mixer/2 Stereo Output/Battery/USB Power/3C Device

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.).

I bought two of these and will probably buy a third soon. The main use is to allow me to connect my Echo devices into powered speakers I’m already using with other devices for better sound. The one pictured is on my desk where I’m using a shelf stereo unit for my iMac sound. By mixing the iMac and my Echo Input, I’m able to listen to music or hear responses from Alexa while also being able to hear alerts or game sounds from the computer. I also hooked an old Apple Airport Express to the third input so I can Airplay audio from my iPhone or MacBook through my desktop speakers. The sound quality is the same as connecting the devices to your speakers directly if the volume controls are set around the middle point. The individual volume controls are great for adjusting the input devices to the same volume. The output volume control can then be used to quickly adjust the overall sound. This is also useful for killing all the sound from your speakers with a quick turn of the knob instead of reaching for a remote, or the volume knob on the speakers. The sound is clear. No audible noise or hiss in my setup. I only have two cons. They are minor. One main thing I would change, and my suggestion to the manufacturer is to move the line out and power connectors to the back. This would allow for a cleaner look on my desk with all the cables running from the back. The power cable on the side and line out in the front adds a bit of a cluttered look to an otherwise nice looking device. My other complaint, but not a major thing for me, is that plugging in headphones does not kill the output to the line out. I can see in some situations that might be desired - for monitoring the mix that you are sending to a recording unit for instance, but it would be nice if either the unit had a switch that let it operate with simultaneous output, or where the headphone overrides the line out. Another option might be to a slightly bigger unit with separate headphone or line out volume knobs. Overall, a very useful unit if you would like your Echo to sound better without having to add to extra speakers in the room. My other unit is in my kitchen where I have an Echo Dot and a TV sharing the same powered speakers.

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.

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.

L'ho acquistato per fare RSI (remote simultaneous interpreting) perché consigliato da una brava collega e l'ho usato per un po'. Non so perché, ma a un certo punto sentivo un brutto rumore di fondo. Non avendo tempo di approfondire, sono passata a un mixer più professionale. Lo tengo ancora perché è piccolo e molto leggero, sperando di risolvere magari un giorno il problema. Ma forse è proprio la leggerezza e scarsa solidità a renderlo meno affidabile.

Ich nutze es mit mehreren Bluetooth Transmittern um mehrere Geräte mit Ausgabe an einen Bluetooth Kopfhörer zu senden. Das klappt soweit gut, allerdings gibt es manchmal leichte Störgeräusche, liegt aber an den Adaptern. Bin zufrieden.

Ik heb hem in een hoekje van mijn (oude maar uitstekende) Yamaha klavinova staan waardoor ik een aantal extra bronnen door de speakers van de klavinova kan laten klinken: - muziek uit mijn ipad om mee mee te spelen - mijn elektrische Roland sax - geluid van de klavinova zelf via midi en een Hammond emulator in een iPhone of iPad Signaal/ruis verhouding lijkt goed in orde

Exactly what I needed to be able to use my work laptop, while listening to music from another source. No fumbling with a screen and an interface to mute the music: just turn down the volume. Sound distorsion at high volume levels though.

Works well enough on battery power but as soon as you plug it into a USB lead to power it, there is a very noticeable 60 buzz. Very disappointing considering it wasn't priced like a toy that it turned out to be.
