Little Bear MC5 Mini Portable Stereo 4 Channel Audio 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

必要となる場合はそんなにないのですが 一つあれば便利かと思います 説明にも何度も登場しますがアクティブとパッシブの違いについては 理解してからの購入をお勧めします

Overall, it does what I needed it to. I have multiple sources sharing a single set of amplified speakers at my (home) workstation. I am able to effectively, and selectively control volume from the different sources, especially when conferencing or sharing from one or another. The line loss is significant, volume is considerably reduced through the device. If you need more volume, you'll probably need a pre-amp. The introduced noise level is very low, so I think amplifying the signal would be an acceptable solution. Overall I like the device. I am going to try higher quality (and shorter) cables to see if that helps. ------ (Edit: After using this for a little while, AND replacing a cable changed review from 4 to 5 stars. It does what I need very well. The controls are very quiet and very good quality. The output needs to be amplified, but that's not a problem with the speakers I'm using.

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.

I have 4 computers in my home office. I feed all of them through this mixer, and then from the mixer to the sound system. It works great, except when I use my headset, which is not amplified. I honestly didn't think a little thing like this would do a good job, but this dinky little 4-stereo-channel mixer kicks serious ass. My only complaint, and it is not really the mixer's fault, is there is a noticeable drop in volume. This is a passive mixer - it has no amplifier, so I am not surprised. There is no background noise, no hissing, no popping. Because of the signal drop when I use my headset, I purchased this tiny amplifier for $20: "eSynic Portable Headphone Amplifier Rechargeable Headphone Amp 3.5mm Audio HiFi Headphone Amplifier with Two-Stage Gain Switch Compatible with MP3 MP4 iPhones iPod Digital Players Computers with 1.2m USB Cable" Search for it on amazon. I plugged the output of the mixer into the input of the amplifier, and now I have an amplified mixer that fits in the palm of my hand and sounds like professional equipment. Happy customer :)
