LiNKFOR 4 Channel Stereo Audio Mixer CX400 Metal Shell Support RCA Input and Output Mini Passive Stereo Mixer with Separate Volume Controls

I am so happy I got this! It works great. And it adds db (a lot) to my dynamic mic. It works perfectly. READ CAREFULLY! Don't make the mistake I initially made. I tried powering directly from a ac/dc wall adapter with powered USB inputs. When I first did that, the noise level was ridiculous. I was about to box and return it. But I figured I'd try the included USB adapter. That was it! All noise totally eliminated. It's as quite as a mouse. I LOVE IT!

This thing is SOLID. Some things to be aware of though: 1. The knobs seem to have different resistances when you turn them. Some feel tighter than others. Having had this for a while now, it seems as if the issue has resolved itself. 2. When turning the volume up on one channel, the others lower slightly. This is kind of expected as this is an unpowered mixer, so there's no balancing. Not really a con, just something you should be aware of. Super easy to use Good volume SOLID build.

I wanted to connect multiple preamps to a single amp without having to plug and unplug connections. This did the trick. No noticeable distortion or color added to the sound. The specs does show up to -12db gain but it's not too noticeable during my testing. Unit does feel quality and seems well built. Mixer knobs have a soft touch feel. Only negative I noticed was some static at very low volumes. Not sure if I'll keep it in my system but I will use it until I find a better solution since it is pretty cheap.

Works great for mixing my presentation output and my mic output. I can balance the sound of each separately. I'm very happy with it.

I was able to implement this without any issues. Sound quality doesn't seem to have degraded by my ear, but I'm sure sensitive measurement systems would detect some degradation. Nothing I'd worry about. The knobs on the top work fine but are closely spaced. My fingers have a bit of difficulty and thus requires fingertip control. Just be aware of that for the size it is. Totally usable, but it is small.... which can also be a good thing. I did replace the output knob with something that feels different. Otherwise they're all the same. All in all, it works and would certainly get another for another application should the need arise for a small RCA line-level mini-mixer. BT recommended

One of the noisest audio devices I have ever purchased. It does work and the build quality is good, but introduces a pretty harsh noise when powered (volume up on video!). This pretty much defeats the purpose for my use case, and I will be returning it.

Exactly what I needed. Solid build, and reasonable price for a powered 4 channel mixer. Using it to mix various outputs - computer/tv/bluetooth receiver/bluetooth receiver - it’s doing the job. No feedback, volumes are good (not low), and there’s a power button.

I was skeptical about this because it's but powered, but it works great. No noise introduced. Very small, so it's perfect for my already cluttered desk

付属のL型の電源はノイズが出ます。5V2A以上の別の電源に交換しましょう。ケーブルは問題ないと思います。同時購入の2チャンネルRCAモデルも同じ症状でした。これ以外は問題ないです。

Der Stereo Mixer verstärkt die eingehenden Signale gut und ohne Störgeräusche. Ich betreibe ihn zusammen mit einem NUx Core Stereo und einem virtuellen Schlagzeug sowie einem Smartphone welches über einen DAC Musik zuspielt. Alle Gerät hängen an derselben Powerbank mit Triggerkabeln (20V,9V,5V) auf Klinke versorgt. Dieser Mixer ist der einzige der sich anschalten lässt und die Powerbank nicht zu einem kurzen Spannungabfall-, stoß bringt, was z.B. der Looper (9V) gar nicht mag. Ein echte Empfehlung !

sterke afwerking, stevig en praktisch van formaat, ik gebruik die om 4 audio bronnen aan 1 equalizer en versterker te koppelen, geen ruis op het toestel ideaal voor zijn gebruik top product.

Ottimo prodotto, fa il suo si può selezionare il canale desiderato o usarlo tutto insieme io l’ho collegato a console , Mac e chitarra, si comporta alla grande

MiniMixer muy estable, pequeña y solida, no mete ruidos ni deteriora el audio, la uso para mezclar las salida de varios componentes como Tornamesa, TV Box, Móvil y CD player en mi sala, no es una mixer para DJ's, es una mixer para salidas de Linea, no tiene preamp phono para tornamesas, tu tocadiscos tiene que tener "Line out"
