FIFINE Ultra Low-Noise 4-Channel Line Mixer for Sub-Mixing,4 Stereo Channel Mini Audio Mixer with AC adapter.Ideal for Small Club or Bar. As Microphones,Guitars,Bass,Keyboards or Stage Sub Mixer-N5

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 have been using this for the last 4 month and the mixer is doing what is suppose to mix the adio from different sources, now i dont use this for music but for playing, i got a Astro a40 trX and realize the ps4 controller does not provide enought power to make the work probaly because they are 50ohm, so i decided to get the astro mix amp but i read on the comments that is garbage y i got it separatly, so i decided to use a mixer to separate and power the audio form the game and the chat, now i have the audio coming out of the tv to the mixer using a optical cable converter to trs, and also the audio frm the chat using a usb audio out on the ps4, now i cant lower down the sound of the chat(because we always have that friend who likes to yell on the game when they die) and increase the sound of the game, by way the mixer seems to have and amplifier option due to i cant rise the volume to 100% or the sound will blow my head, with having it on the middle is more than enough, i also have a bluetooth receiver conected to one of the audio in, and can play music from the phone and listen to the 3 audio sources at the same time.I have probably complicated myself by doing all this, but i have no regreats.I saw people saying this is not dual channel, but i have no problems wearing headphones with this, i can locate footsteps sound really fast and clear and music sound incredible, i looking to get a audiophile headphones to the mixer power.UpdateI said i thing this thing may have an aplifier but now im sure, i justo got the massdrop sennheise hd 6xx and as you know those are 300ohm, and the mixer can drive then on easely and make then works so good that i believe im been hearing to trash all my life, now i play on the ps4 with the hd 6xx and still get a great sound quality, so if you are planning to use this on a really heavy audiofile headphones(no more than 300ohm because i have no tested any of then yet) buy this you wony be dissapointed

I picked this up a while back to combine audio from a gaming console and laptop. It functions well, build quality is solid and it has plenty of headroom for volume. I used this unit for over a year before I noticed that the bass was attenuated. I noticed this after I purchased a decent set of headphones and was going direct into a DAC—and then when I switched back to the mixer the drop in bass was very obvious. I think for the price and functionality this is a good value , but I ended up switching to a different (and more expensive) solution that maintains a strong bass signal. If bass isn’t much of a factor for someone, this is an easy unit to recommend.

Great value and performer. Potentiometers are smooth and feel reasonably solid. Nice compact metal case. No real perceivable noise, though I didn't hook up an oscilloscope to be sure. Just know that you will be connecting up to five devices (4 in, 1 out), and so there is a big potential for ground loops. I was disappointed at first when after setting it all up, the noise level was far too high. But I installed a ground-loop isolator between this device and the output of one of my noisier devices (see other review), and the problem was immediately solved. My only wish would for it to be a little more portable - as a passive device (no power required) or one that can be powered my a now-common USB battery pack.

The media could not be loaded. Good quality for extra volume control. I'm using it for an extra adjustment over my headphones while gaming.The design makes it easy to hook up what you need, in a compact footprint.The signal quality is great, I don't hear any distortion.Very good for the price, I would buy again.
