Douk Audio Little Bear MC5 Mini Portable Stereo 4 Channel Mixer Passive Live Studio Console Recording Low Noise (No Power Needed)

Necesitaba mezclar un instrumento midi con el sonido de la compu. Y esto cumple el objetivo. Es pequeño y a buen precio

This little jewel box is a passive stereo line mixer. The inputs are adjustable in impedance with tiny switches. There is no external power supply required, instead, this design steals power from the sources and the amp it's plugged into. The designers have delivered a unique and fairly priced device. Today I'm using it with a Headrush GO amplified stereo speaker which only has one TRS line input, this little mixer let me plug in guitar amp modelers by Line6 and Mooer modeler plus a little drum machine, all battery powered - it's our portable, miniature, jam rig for my wife and I - to use when the power goes out. The little mixer has no metal enclosure - it's basically a stack of thick PC Boards - you'll want to keep it away from big noise sources (not hard using an all battery powered rig). In spite of there being no metal or plastic enclosure the small size of this mixer makes it a joy to use anywhere and it is surprisingly low in noise. This little mixer has quickly become a favorite due to no-power-required and the four inputs, not to mention every input has its own volume control and there is an adjustable master output level. If the price goes up then there is competition but at the current price nothing touches the BEAR, grab one of these while you can (if you're an audio geek like I am). GOOD MUSIC TO YOU!

It’s not just a perfect little passive mixer you can basically throw in a shirt pocket, it’s beautiful. Love the dip switches to change the impedance. Clean clear sound, solid build. Wish everything I owned was like this.

I’ve been on the fence about buying the XBOX Wireless Headset for weeks now, due to the convenience of a hassle free way to hear game audio while also chatting to my friends on Discord (who don’t want to use party chat). But, I already own really good headphones, so dropping the money on more headphones that don’t have as good audio quality held me back (have you seen the bass bump on those things?!) After LOADS of research I stumbled across this Little Bear product, which you can get from AliExpress/Amazon for ~$40 or less. It’s a 4 way passive (no power needed) AUX mixer that routes everything to your headphones. You simply plug in your controller AUX output into Input 1, your device running Discord to Input 2, and your headphones to the Output. Some reviews online talk about the fact these units came with a 10K resistor that took way too much of the volume away, and that when complaining, the manufacturer responded saying people should just solder 1K resistors on instead. I was prepared to do this, but to my GREAT surprise, it seems like these units have been silently revised and now come with a 1K - 4.7K resistor switch inbuilt (pictured), negating the need to solder anything. What this means: I can confirm that while the audio level still definitely drops in volume, I am running a pair of Sennheiser HD6XX (high ohms, hard to give enough juice) with the input/output knobs at 100% and am satisfied with the maximum volume it is outputting. I can then blend in my other device (Discord) to taste. This is quite the achievement for a cheap passive device. The main negative I would note is that the volume rotors don’t seem to be very linear, so most of your granular control comes from the final 10-20% of the rotation. No big deal. So - if you’ve got good headphones already, and happy to still deal with a few wires, I heavily recommend this product as an elegant solution for a problem Microsoft doesn’t seem to want to fix outside of selling their branded headset. Just make sure you confirm it’s the revision with the 1K-4.7K switch, or be prepared to do some light soldering with 1K resistors if not.

Pros: - Cumple con su función - Permite bastantes entradas - Controles de audio individuales Cons: - Las resistencias que tiene el circuito bajan bastante el volumen, es NECESARIO tener un amplificador
