## Description

Main Description: Maker Hart JUST Mixer S is a powerful and portable mini mixer that can support music players, smartphones, game consoles, and more. It's an ideal mini mixer for those who want an affordable, reliable kit with a 3-channel design, allowing you to connect up to 3 inputs and 2 outputs simultaneously, all through a 3.5mm jack. Powered by 2 AA batteries or via 5v USB, it's designed to be used on the go. You can use it for your home recording studio, music club, street venue, or anywhere else you want to record or perform. The mini mixer also comes with a carrying case for added protection and is used by individuals, musicians, audio technicians, and DJs to monitor audio output. Maker Hart was established in 1975 with a mission to provide the very best professional sound effect equipment. Over the past 40 years, we've sold millions of our equipment to musicians, sound engineers, and renowned producers across the globe. We design high-quality products built for impeccable performance and made to withstand the test of time.

Review: 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: 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.

## 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.

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.
