Headphones Amplifier-N6

I have been thoroughly amazed by the quality of this mixer. This mixer takes 4 sources and combines them into one. But it doesnt just combine them, it runs each source through its own mini amp. This allows for good volume control of the sources, along with preventing any sort of feedback or noise traveling back up the wrong way. It keeps each source completely separate. This separation keeps the noise incredibly low. On top of that, each little mini amp is incredibly clean. In most situations, I might as well be running my DACs straight to my proper headphone amp or speakers. If you have any trouble with static or noise, check the wires you used. Any sort of noise introduced from a bad wire or adapter will be very audible. With one cable, I could hear when I moved my mouse or dragged an element in a work space. I couldnt tell you how the wire was picking it up, but swapping it and the 1/4inch adapter for that input fixed the issue. If you have noise, its likely not because of the mixer. In the end, I love this mixer more than any regular receiver. No input switching, just listen. I originally got this so I could listen to my records without having to stop watching streams or working on my computer. I didnt want to have to get a separate sound system just for the record player. I also didnt want to have to switch between the 2 because i needed the audio from my computer as well. Combining the signals with a regular splitter was a big no no. Any time the record player wasnt running, it would distort the combined signal. Now i can listen to records, play/work on my computer, with an additional source for my robot voice assistant to also crank out when i ask it to. Just for me, its simple and easy. Im sure that any Pro user, actually using this mixer for a professional, more intended purpose, will find this little mixer to be absolutely perfect for most applications. fifine have really proven themselves to be an amazing company that cares about audio.

I bought 2 of these little line mixers because they solved some difficult audio interface mixing issues. I use one between my PC and my USB mixer interface to route audio from a 2nd audio interface for OBS recordings instead of using Voicemeeter mixing software. If you have issues splitting the mic signal and your DAW or a guitar signal, this line meter can help you. It's tricky but it is easier than using Voicemeeter. This line mixer is also very quiet without hiss so it is worth its low cost definitely.

I wanted to use a basic mixer to have PC sounds and game console sounds (passed in through 3.5mm) come into my headset together. The fact that this mixer uses 6.35mm plugs meant that I had to buy those adapters, but they were cheap so that wasn't a big deal. As many have mentioned, there's some scuffy sounds when adjusting the volume dials, but when they're still, there's no issues with that. The main 2 issues I had and how I overcame them were: Plugging my headset into the mixer directly, due to the mixer's potential high volume output, meant that there was a bit of white noise constantly into my headset (even when there were no sources plugged in). This would be alleviated I think if the mixer had a master "volume out" knob as well, to lower the output volume to where the noise was inaudible. This type of noise happens when a lot of sound sources are blasted up to extremely high volumes, which is essentially what was happening since there was no way to lower the output volume. What I did to alleviate this was just plug my headset into a volume-adjustable 3.5mm extension cable instead and lowered that, which eliminated the white noise while keeping actual sound sources plenty loud (accomplishing the same thing as a master volume knob). This cable was pretty cheap (I had one off amazon from before), so that is easy to get around. The other is that, my first mixer that came in had quite a bit of actual static, as in it was defective. It was pretty easy to contact FIFINE though. As they mentioned through another review, you can message them through Amazon through the "Ask a question" button, but I emailed them at the web(at)fifine(dot)cc email listed in the manual. They sent me a new one right away, and didn't even ask me to return the old one even though I offered to, so despite the defect, the service was great, and the new one works great. So a few issues (namely scuffiness when turning dials, no master volume out to remove noise, 6.35mm instead of 3.5mm) but it's cheap and once you get passed the issues, it works great. Some reviews were asking about if it's supports stereo and it does, you just have to make sure you get 3-section/TRS (tip-ring-sleeve) adapters instead of 2-section/TS adapters. I found a pack of 3 on here for $7 (I only needed 3), or a 5 pack (which would give full functionality) for $9. Between those and the volume-adjusting 3.5mm extender that I needed (which I already had), which I think was around $5, and a couple male-male 3.5mm cables (pc to mixer, console to mixer), a whole setup like this is probably around $40, which is still plenty cheap for the entire setup. Would recommend if you're looking for something similar.

As the description says I am a drummer. This little thing is great. I can take the mix from front of house (minus me), any samples, band click-track, my electronics and then run them through this little thing to my in-ears. The mixer is powered so it will boost the volume over what the original device is delivering. I tested this with a direct line from my boss metronome to my in-ears vs going through this mixer. The sound out of the mixer was several times what the direct feed was. Same for the laptop, and Roland drum brain. I like that I can set the individual volumes as I go along. Other have said that the pots were noisy but I do not find that. Every so often I get a little fuzz when turning the knobs but that's it. I originally bought this just to use in the practice room but it is now in my bag when we gig. There is no eq (just line volume) so if you want to tweak the mix you will have to condition the signal through before this. I still use a small monitor behind me for feeling the bass. Overall I think this is a great buy for the casual musician who needs a basic mix in the ears while practicing/playing. Are there better systems out there, sure, but for $22 this thing is a steal.

I wanted a replacement for the crap DI box that came with the meinl cocktail cajon kit, and this is INFINITELY better than the plastic crap that the meinl kit comes with. It's a sturdy metal box, it's extremely intuitive for where to plug inputs vs where to plug in the output, and it's super easy to use straight out of the box. There's no power on/off - plugging in the power will act as "on", and unplugging it acts as "off" For someone who does not know what I'm talking about, and just as an all around review: I'll say that I'm plugging in electronic drums that have their own independent inputs and volume knobs to this DI box. I'm getting the best sound output by turning all the volumes to max on this box, and then using the individual volume controls on the drums and amp. I would guess that this might be the best way to get optimized volume for other instruments - turn the volume to max on this box, and then control the volume as needed on the individual instruments and amp. Very pleased overall with the ease of usage straight out of the box. Very happy that this works on my drum kit

I'm using this device between my headphone DAC and amp to mix audio from other devices and multiple outputs on my computer (SPDIF to a Schiit Magni 2 Uber for main audio, cheap USB dongle for a separate voicechat stream, and a cheap HDMI audio extractor for surround to stereo downmix). It works well and doesn't seem to introduce any extra noise to the signal, but I can definitely hear a loss of high and low detail over headphones versus a direct connection from my DAC to amp. The mixer properly isolates individual inputs from affecting each other, unlike basically every non-powered mixer I've tried. It will, however, introduce clipping if your input device's volume is too hot or you set the knob too high, so make sure your levels are set properly. Another less obvious quirk is that it can become a path for a ground loop since it has external power, so be sure you isolate devices accordingly and keep a shared ground for everything you connect to it.

I bought this 4-Channel Line Mixer, to mix a dry signal and the processed signal from an Acoustikar Acoustic Guitar Simulator Pedal. The Acoustikar pedal produced too strong of an effect. This little mixer allowed me to dial in the desirable amount of effect perfectly. Its size and quality are perfect for my needs since this is part of my pedal board setup. The mixer is quiet, and I have not heard any noise while adjusting the levels, perhaps they address that issue in the last few years. The only negative is that it runs off of 12 volts instead of 9 volts like the rest of my other petals. This requires me to use the supplied 12 volt power supply along with the 9 volt Power supply I use with my other petals. On the whole, this mixer does exactly what it's advertised to do, At an extremely affordable price.

UPDATE: I bought brand new nice 6.35mm male to 3.5m male cables. Plugged all my sources in, and it actually sounds worse. Not as much line noise now, but sounds like sources are 25% level and in a cave. If I pull the 6.35mm ends out of unit about 1/8th inch, they sound better and louder. Its like its not getting L/R channels when its plugged in all the way. They are TRS double black lined ends for full stereo. I’m giving up. It shouldnt be this hard! I have 3 stereo sources that I need to mix for streaming on twitch. I ran 3.5mm stereo cables from the computers soundcards and plugged them into 6.35mm adapters so I could hook them up to this mixer. With one source attach, I had zero noise. As soon as I plugged in the 2nd source, I had terrible noise. Attaching the 3rd source actually made the noise a bit less. The only way I could eliminate the noise was by turning the volume knobs to <20%. At that point, the input volumes were too low. Also there is no way to adjust output gain. Only gains of input can be adjusted. I am buying some 3.5mm male to 6.35mm male ended straight cables to see if I can reduce the noise. So I have spent more on 3 cables than I did on the mixer itself. I should have just bought a Maker Hart Loop. I may end up sending all this back if I reduce this noise significantly with new cables.

Its a perfect one for guitarists, pianists etc. I tried to connect it in another mixer, but its not for that purpose. Aprt from that all the knobs are top notch , the quality is awesome and its value for money.

I really wanted to like this. It’s a nice build and is quiet on the inside ….but on the outside … the dials are just horrible and I mean HORRIBLE to use! Whoever made the decision to put smooth shiny aluminum dials was going for looks and not function. DO NOT BUY if like me you are in wanting to quickly change instrument on stage and turn one up and one down quickly …these dials will screw you over! You could buy some cheap plastic dials to overcome some of the issues but that’s throwing money at the problem. DESIGN FLAWS: 1/. The metal dials are highly polished and so have no grip to the point where when you go to turn the pots (which are quite stiff) the dial actually slides in your fingers as you twist. It takes several turns of the dial to turn up or down fully. 2/. In addition, the white swoosh marker graphic on the casing showing 0 -10 (180 degrees of rotation) is not matched to the amount that pot actually turns. It actually rotates much further through 270 degrees ie. 3/4 of the way round from ‘nothing’ to ‘max’. This amount of rotation makes it hard to figure at a glance if you are at full volume or whether just a quarter of a turn away, you are actually on zero volume (see photos - the dial on the left is on minimum, the dial on the right is on maximum). 3/. To make matters worse the top of the dial is highly reflective so confuses seeing where the top of dial white line is at as there can be several reflections . 4/.It also arrived nearly three weeks late but that’s probably Canada Post as a courier. It’s going back as the dials make it unusable on stage for my purpose.

It is advertised as low noise. In the application I was using, it, in fact, had a loud ground loop buss that I couldn't even eliminate with a ground loop buzz eliminator. It might not be a fault of the product at all, but I couldn't use it and returned it.

Very nice and compact. Good product which can be used as a semi mixture.

Value for money and good quality
