4 Channel USB Interface Mixer, DJ Sound Controller Mini Mixer Professional Digital Audio Portable Sound Mixing Console with Sound Card & Bluetooth Function for PC Recording - Depusheng M4, Black

I am an audio professional who has worked with every kind of sound SYSTEM you can imagine for 60 years of my life. I bought this to get access to it's 256 special effects. I was thinking, for the money, this thing can not be any good. Boy was I wrong. The brand has always been pretty good but never this cheap and with so many features. I ran a harmonic distortion test on it and found it to be better than most licensed broadcast equipment. I hear people complaining about noise. Yes the pots are cheap and the switches are even cheaper but if you need to slide pots up and down all day long, this is not for you. Get a broadcast board. The pots for a broadcast board are not cheap. Most cost more than the total cost of this board, but I must admit, if one sets levels and uses it that way, they will realize this a is damn good little board. Good enough to be very, very usable if used as a sub mix board. I am only going to use it with one mic to get the 256 special effects, which are nothing short of AMAZING! The workmanship of the first board was not the best. I had to send the first one I got back. The switch you use to select an effect was not working well at all. I sent it back and got another in two days. Don't be afraid to be fussy. Amazon folks are good people. Replacements come fast and this one did. I am having a blast reviewing all the special effects on this mini board. I am hearing some of the best effects I have ever heard on any audio board at any price. Get this board. Put it in your closet. It's so inexpensive, some day you will need it and it will blow you away like it does me. 256 effects for just a few pennies per effect. Nothing beats that!

This mixer was incredibly easy to set up and use. All the channels and controls are intuitive, and it performs exactly as expected. Great sound quality and reliable performance—perfect for small setups or home studios. Couldn't be happier!

Alright so I bought this for live events at our workplace - I have a set of wireless mics and the volume control was always really wonky and subdued so just needed a mixer in between. This does that phenomenally - love the variety of inputs, the controls, and the PORTABILITY. I can power this thing off a power bank during the event and gives my speakers a lot more input capacity. For the price, its really fantastic for pop up live events. PC-USB CONNECTION: I can confirm that when you connect this device to your computer (I'm on a Mac) you will get a consistent hissy noise in the background of everything. It's not related to inputs, and I've tried different USB cables and this thing is VERY finicky with the cabling it wants (USB A to A) Did not register with any USB C to A cabling. So you need a dongle with any modern device. Even through a dock with native USB the hiss is still there. I tried testing it as a podcast device with XLR mics - using something like Adobe Audition you'll need to apply a realtime DeNoiser or the like to get rid of the hiss. You can def do it in post. But compared to my NT-Rhode its noticeably noisier. But not totally unusable in my opinion as others have said. For professional recording into a computer I would not recommend this device. But it can do it. I tried running the main mix out and the headphone jack into my mac and you have to have a dedicated line in/mic port or other intermediary device - really doesn't jive with the headphone/mic combo ports. Overall I think this is a fantastically affordable mixer for baseline live events, speeches, etc. Not ideal for podcasting or computer recording compared to other boards.

All aspects of the unit are filtered through the price, and it’s quite great given that. If you expect amazing tactile feel, don’t, and I’m sure it has low noise, I don’t hear much if any, but my main mixers’ noise output is certainly lower. My unit seems to have a similar FX button toggle issue, when you scroll a preset the number flashes a few times giving you time to confirm, pressing, what I assume is a standard press, does nothing and it shortly resets to its current setting making it effectively stuck on whatever it happens to be on, preset 189 (EDM I think, which was fortuitous I suppose). A fix instead on my device was a FIRM press, not standard button click, pressed firmly (more than feels right honestly, but it’s fine) and held for a fraction of a second (it’ll stop flashing) works 9 times out of 10. The FX sound really great as well, was pleasantly surprised once I got the button working for me. So I’m going to give it a 5 despite that caveat, it’s much more feature rich than one of the smaller volume channel only style mixers, though it’s also much bigger, I’m using it as a portable back up and it’s extremely capable for the price.

Las funciones de bluetooth y usb solo funcionan cuando el mezclador esta conectado a un computador, cosa que resulta poco funcional porque si quieres reproducir música desde tu celular o usb dependes de una computadora

Works pretty well for the price.

Amazing little mixer. Variety of power inputs and it even includes effects.

The mixer works great, but the USB to USB cable they send with unit is no good. It will over heat and mixing board would disconnect from the PC. What i did was used a braided USB to USB cable that i just so happen to have and that worked great. The mixer even worked better. You don't have to use the USB-C cable to power the unit on if you are going to use the USB to USB cable. I also have the 8 chanlle mixer by the same company it works great as well. The little 4 channel mixer is good, they just need to send a better USB to USB and USB to USB-C cable with the unit.
