JUST MIXER 2 : USB Audio Mixer - Compact USB Powered Stereo Desktop Mixer w/ 3 In / 2 Out (3.5mm) plus USB Audio Output

I have to rollback my previous review stating that the Just Mixer is noisy, and issue an apology. I found that the camera input (Sony A7II mic) where I was connecting the output of this mixer has a different impedance, hence I needed an adaptor. I purchased the movoPhoto Line to Mic cable and now the setup works perfectly, no noise at all Now I connect a wireless lavalier to Input 1, the laptop output (focusrite Scarlett solo) or ipad/phone to the Aux input, and the mixer output directly to my camera. Using Reaper (DAW) for my background music with EQ I managed to balance all frequencies that the camera does not equalize and basically no adjustment is needed on the audio side of the final video edit.

This product does not work as described. The USB interface does not function correctly. I have connected this to multiple computers running Windows 8 or 10. On all computers, the system chirps and recognizes something is connected to USB. However, there is no reference to a new device, let alone an audio device anywhere on the system. Device manager is unchanged, there are no changes to system audio settings, nothing. So, I spent north of $50 on a device that does the job of a $15 device.I tried to contact Amazon & return, but was told that I was outside the return window even though it was a gift & not opened until after the return window closed.Like I said, stay away.

translated textThis product is a little expensive for 50 dollars and 30 to 40 dollars would be fine.Because there are some problems. (It's a little tricky to handle with a portable mixer that anyone can use.)1. Contextual noise1A Connecting a mobile phone charging with an aux cable will cause noise (like a ground problem). /*The remaining current flows to the instrument)When the power adapter and the instrument are close together, there is sometimes noise.(+ Sometimes there is noise when you plug in 2A power. /2A When you plug in the power supply and connect the charged cell phone with the aux cable, it makes a serious noise./1A Power is required. 1A Plugged in to make no loud noise.)2. Small output (not resolvable with USB output...)The output is small. However, increasing the input signal will overload it.The 3.5mm monitoring (headphone) output can be set higher than the 3.5mm stereo output.Monitoring (headphone) output is recommended.There is no method for USB output. (An additional external amplifier or editing may be required.)3. Unknown overload indication standard (power blue LED/overload pink LED/3.5mm output?)When using a USB output, a pink light doesn't overload the output.Just because there's no pink light doesn't mean there's no overload.[When using USB output, even small volumes often sound already overloaded.So I can't turn up the volume. It is also relevant to the above issues.]4. miscellaneous mattersMonitoring (headphone) output does not work with the master volume slider.So there's no way to see what the volume of the actual output is like.(I don't think we should call it a monitoring output.)It's written in the product description.(Note: The RCA and headphone outputs are connected for connection toan amplifier or powered speakers and are not affected by the master volume level.Note: The RCA and headphone outputs are intended to connect to the amplifier or power speakers and are not affected by the master volume level.)Unable to use pin mic.It says that only a microphone with a separate power source can be used.The disadvantage is that pinmikes don't need a big power source.However, it costs twice as much to use just mixer M.No aux in volume control slider.I personally have three 3.5mm inputs, but I have to separate them into aux.I don't think it's necessary to remove the slider and make the Gain knob.The volume is small, but I don't know why. I'm not an acoustician.I only mentioned the bad points, but there are good points.It's almost the only 3.5mm portable mixer.Using 3.5mm, which is accessible to the public, it would be good for audio primers and strippers.In conclusion, small problems (?) make you feel slightly more expensive, but if you use them well, it's not bad.원문 (한국어)이 제품은 50달러라기엔 조금 비싼 듯하고 30~40달러면 괜찮을 것 같습니다.왜냐하면 몇 가지 문제점이 있습니다. (누구나 사용 가능한 휴대용 믹서라기엔 다루기가 조금 까다롭습니다.)1. 상황에 따른 잡음1A 전원을 사용하며 충전 중인 휴대전화를 aux 케이블로 연결하면 잡음이 납니다. (접지 문제 같습니다. /*남는 전류가 기기에 흐름)전원 어댑터와 기기가 가까이 있으면 잡음이 날 때가 있습니다.(+ 2A 전원을 꽂을 시 잡음이 날 때가 있습니다. /2A 전원을 꽂고 충전 중인 휴대전화를 aux 케이블로 연결하면 심각한 굉음이 납니다./1A 전원을 꽂으라고 되어 있습니다. 1A 전원 꽂으시면 굉음은 없어 집니다.)2. 작은 출력 (USB 출력일 때 해결 불가...)출력이 작습니다. 그렇다고 입력 신호를 높이면 과부하가 걸립니다.3.5mm 스테레오 출력 보다 3.5mm 모니터링 (헤드폰) 출력이 더 높게 설정 가능하니모니터링 (헤드폰) 출력을 사용하시는 게 좋을 듯 합니다.USB 출력의 경우 방법이 없습니다. (별도의 외부 증폭기나 편집이 필요할 듯함.)3. 알 수 없는 과부하 표시 기준 (전원 파란 LED/과부하 핑크 LED/3.5mm 출력 기준?)USB 출력을 사용할 때 핑크 색 불이 들어온다고 해서 출력에 과부하가 걸린 것이 아닐 때도 있고핑크 색 불이 안 들어 온다고 해서 과부하가 없다는 건 아닙니다.[USB 출력을 이용할 때 작은 볼륨에서도 이미 과부하 걸린 소리가 나는 경우가 많습니다.그래서 볼륨을 높일 수 없습니다. 위의 문제와도 관련이 있습니다.]4. 잡다한 문제모니터링 (헤드폰) 출력은 마스터 볼륨 슬라이더가 작동하지 않습니다.그래서 실제 출력의 볼륨이 어떤지 확인 할 방법이 없습니다.(모니터링 출력이라 부르면 안될 것 같네요.)제품 설명에 적혀 있었네요...(Note: The RCA and headphone outputs are intended for connection toan amplifier or powered speakers and are not affected by the master volume level.참고: RCA 및 헤드폰 출력은 앰프 또는 파워 스피커에 연결하기 위한 것이며 마스터 볼륨 레벨의 영향을 받지 않는다.)핀 마이크 사용 불가.이것도 제품 설명에 별도의 전원이 있는 마이크만 사용 가능하다고 되어있지만큰 전원이 필요한 것이 아닌 핀 마이크도 작동이 안되는 것은 단점입니다.그렇다고 just mixer M을 사용하기엔 가격이 두 배나 됩니다.aux in 볼륨 조절 슬라이더 없음.개인적으로 3.5mm input이 3개나 있는데 굳이 하나를 aux로 구분해서슬라이더를 없애고 게인 노브를 만들 필요는 없다고 생각합니다.음량도 작은데 왜 그런지는 음향 전문가가 아니라 모르겠네요.너무 안 좋은 점만 말했는데 장점도 있습니다.거의 유일한 3.5mm 휴대용 믹서 입니다.일반인이 접하기 쉬운 3.5mm를 사용해서 오디오 입문자나 스트리머 입문자에겐 좋을 듯 합니다.결론적으로 자잘한 문제(?)들로 가격이 살짝 비싸다는 느낌이 들지만 잘 사용한다면 나쁘지 않은 제품입니다.

All I wanted to do was pass audio from two devices to one set of headphones. This product does that in a very portable efficient manner. I have not encountered any of the 'white noise' issues I read about and was slightly concerned about prior to ordering. I am powering this device from a laptop USB port with a generic cable and the sound, while not great....is very good and the degraded quality isn't noticeable after 15 minutes. I am using a higher end set of Sennheiser headphones. If you are looking for a portable mixer that you can throw in your laptop bag without it taking up much space than this is the product for you.

Great mini audio mixer that can used with or without a computer(usb)

Plugged it in, set it up. Turned it on, blue light for about 3 seconds and nothing.... dead. Totally disappointing and have no confidence in this product. Why replace with another one just to have it fail before I need it to work.

I'm impressed! Damn thing works great! Exactly what I needed. Very good quality build. The slider controls feel solid. Simple EQ but wide enough frequency for all applications. Easy to control with one hand.

My only complaint is with the volume input overdriving too close to the center positiuon...
