FIFINE N5 Ultra Low-Noise 4 Channel Stereo Mini Line Audio Recording Mixers

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.

Works great! It has enabled me to input 3 guitars with pickups plus a microphone into one channel.

I purchased this mixer to be able to mix my bass guitar in one channel and my Korg Monologue in another. I was pleasantly surprised to see that the unit was well built and had sturdy construction. Well packed and included a 12v power supply. All the knobs felt nice and smooth. Placed the unit on my keyboard desk and proceeded to make my connections. Plugged the output into my Hartke bass amp, plugged my bass guitar into channel 1 and turned on my bass amp. I adjusted the volume knob for channel 1 and got a nice volume setting. I plugged my Monologue into channel 3. I realized I needed to power up my power strip so my Monologue could be turned on, so I did so. Immediate loud hum. I then realized that when I powered the strip for the Monologue it also powered the mixer. Not good, terrible loud hum. Then ---*what???*--- when I set the volume for the bass guitar the mixer unit had not been powered up. Hmmm, I then turned on the Monologue and disconnected the power plug from the mixer. No noise, no hum...the Monologue sounded fine, adjusted the volume for channel 3, checked volume on channel 1 and everything sounds great. So obviously the mixer unit doesn't need power to work. That's the reason I only gave 4 stars. Not because I couldn't get it to work, but because the option of not connecting the 12v power supply wasn't mentioned.

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.

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'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.

When nothing is plugged in, it screeches. When things are plugged in it screeches in different tones. This unit is garbage. Do not waste your time or money on this.

Good product

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.

Compact good excellent working

Value for money and good quality
