Asmuse 4 Channel Audio Mixer, Low-Noise Mini Stereo Line Mixer, DC 5V Power Supply Mixer As Guitars, Microphones, Keyboards Mixer

I got it to patch a bunch of different instruments into my pedal board simultaneously. It does the trick. I like it has a USB C power option. I run it off my power supply that that has a USB built into it. It's small and fits right into my pedal board. It's a powered amp so it has knobs and stuff so... I usually put them right at 50%. Works fine. It has stereo but I never use it. I have my electric guitar, keyboard, and microphone plugged right in. Just got to fiddle with the knobs to make everything sound equal and good and it's fine. It's nothing to write home about but it's really small and works totally fine. Feels good in the hand. It's made out of metal. I like it, it does exactly what I want it to with no hassle.

Worked quite well. I use it for band practice and mixes the music very good.

I just needed for my computer , as desk space is Premium for me. I used it to run two Synthesizers in to my DAW software. Sound quality is Adequate,I run the main output to an Audio interface then to the pc! Seen bad reviews on this mixer but,i have seen none of the Issues mentioned! WORKS AS ADVERTISED! i just think the bad reviews were from people who have no clue what they are doing!

After reading the reviews here, I was hoping the issue where the right channel on Input 1 was much louder was solved. So, I ordered 2 of them, and now I'm returning them. I tested them and I was not prepared for just how much difference there was between left and right on Input 1. Right was possibly twice as loud. The rest of the inputs were fine. So, if you only need 3, or just mono, this mixer is for you. I will say that the mixer feels solid, but it's a shame that it can't do it's one job.

I use these with my mega boogie tube amp. It allows me to play music, backing tracks and play the guitar and listen to it all via head phones

Worked for me to combine multiple audio sources. Good form factor and build quality.

First off, I want to like this mixer a lot. It has everything I would want in a small, compact mixer. The body is metal, looks good and feels nice, the knobs don't feel cheap, it has 1/4" inputs, and it's powered. Unfortunately, it seems that it's too good to be true. The unit I received has a significant volume imbalance on Input 1. In stereo mode, the right channel is louder than the left, making it completely unusable. It isn't a small volume difference either. If I had to guess it's 60-70%. Inputs 2, 3, and 4 work properly and have equal L/R channel volume, equal to the volume of the left channel on Input 1. The right channel of Input 1 is equal to the source volume. I don't know if that means all other inputs are the correct volume and the right channel of Input 1 is too loud, or that the right channel on input 1 is the correct volume and all others are lower. Either way, it's not working as intended and something is wrong. I changed cables, changed input devices, changed output headphones, and the problem persisted.Normally this wouldn't be a big deal because lemons happen and I would exchange it and everything is fine. The bigger problem arises when I did exchange it and the replacement unit has the same exact problem. The new unit has the same volume imbalance on Input 1's right channel as the first one. I don't know if I got unlucky twice in a row, or there is a serious design flaw in the circuit causing this problem affecting all of them. I don't know if I want to try a THIRD unit, because seeing Quality Control pass stickers on both of the units I received doesn't inspire much confidence that I won't be wasting more time. How did two of these pass QC when the problem is audible with default settings on the very first input? Only 3 inputs working in stereo isn't acceptable when the product is supposed to be 4 channels.I really want to like this mixer, I just wish it worked properly.If everything worked as intended, the only other nitpicks I have include the MONO and STEREO switch positions being labelled wrong on the case of the unit. Stereo is in the out position, and Mono is when it's clicked in. The diagram on the front shows the opposite. The red power LED is very bright, to the point of being blinding. Some people may like that and some tape takes care of it, so it's not a big deal.

All four channels hissed regardless of whether the mono/stereo button is activated. This is being returned.
