JUST MIXER 5 with Bluetooth Input & USB Audio Output - Compact USB Powered Stereo Desktop Mixer with 5 In (3.5mm / Bluetooth on CH1) and 3 Out (3.5mm / RCA/USB)

Nice for combining several desktop audio sources. I use it to combine audio from a Mac, iPad, and iPhone, and listen either on headphones or small powered stereo speakers. Very small size is great for desktop. The mini stereo jacks are great, no need for adapters. Seems to be good as far as noise is concerned. It's best to have the source audio loud so that the mixer doesn't need to amplify much. (I hear some hiss with no audio playing, but devices connected and turning the gain way up... but that is to be expected and much is due to the source audio). I don't really need the equalization, but they seem to work.The bluetooth input is a very nice feature, but could be improved. The gain needs to be more (like twice or 3x) on the bluetooth (channel 1), I have to turn it all the way up, and then it's still not really loud enough (I also have the iPhone set to max volume). The bluetooth pairing works well, but when it is not paired it blinks -- which is annoying so I have to switch off the bluetooth when not using it (a very tiny switch on the side that is hard to operate).I'm using this for only listening, haven't tried the USB --> Mac input yet. This might be useful for audio production, but I haven't used it for that.

It works as intended, it is portable, light weight and looks nice from far but quality definitely could be improved. It is a Plastic device, even the rotating knobs for " Equalization" (In reality is bass-treble control).I connected to a pair of self-powered pair of really good quality Monitor speakers (250W rms each one) that normally auto power on when signal is detected... but as soon as I turned on the Mixer I get a really annoying and loud BUMP coming from the mixer (So, now I need to turn on the speakers manually after I turning on the mixer). The range for the Bluetooth is limited to 30 to 40 feet, which is pretty decent. There's some attenuation or not gain inside of the mixer... This is real critical for Bluetooth (Port 1), I need to put the sliding volume at maximum and still is not getting enough volume in the Speakers compared to the audio coming fro other sources (PC or CD Player).Other than that, you get what you paid... a 79 dollar mixer.

I don't leave a lot of reviews, but since there aren't many reviews on this, and the reviews are mixed, I feel my review will help one of you decide whether or not to purchase this.Unless there is a quality control issue that others experienced, this mixer is brilliant! Mine works perfectly. Sounds great. I will update my review if the hardware fails, as I have only had it a few days now.Some observations:The RCA output is not variable. It is a full-volume pass-through of the sum of all inputs and their volume controls, in contrast where the 3.5mm output on the back is controlled by the 'VOL' slider. This was not documented in the Owner's Manual. Luckily this is perfect for my use, because I have my main amp for my speakers on the RCA out, which has its own volume control, then I have my sub-woofer attached to the 3.5 out, and this way I can control the sub-woofer level with the VOL slider! I can get the perfect mix of bass for any song easily.The headphone jack on the front is ONLY controlled by the 'PHONE' dial. This wasn't clear to me either, but it is not a problem. Adds to it's versatility.

If any device that you use is plugged into a wall for power, you will get a ton of noise that you constantly have to manage by playing with the input levels and volume. Basically just an extremely cheap mixer that won't work for most computer setups, a reminder that you get what you pay for.

I read the other reviews and wanted to give this product the benefit of doubt because it was really the only mixer that allows Bluetooth as a channel, but this really nice feature couldn't outweigh the negatives.I really liked this product initially because it's small and looks great. It fits perfectly with my minimal desk setup. The first thing I tried out was the bluetooth, and that worked perfectly. Although I needed to really push the volume all the way up, it wasn't a deal breaker. The deal breaker was the same as the other reviews, as I feared, which was the STATIC noise. I had my Macbook going through the first channel w/ bluetooth, and then another Windows computer going through the second channel, and those seemed to work fine. But when I tried to hook up my Amazon Echo Dot to another channel, there was static noise coming out, even when nothing from the Echo Dot was playing. I even tried to turn off the bluetooth and hook up my Macbook with an aux cord, but the static stayed w/ the Echo Dot.If the bluetooth feature is what's attracting you to this mixer, you may have a different experience and it could work out for you. Otherwise, I recommend MakerHart's Loop Mixer from the same company. Design looks similar and works with all of my devices w/o the static.

Have used the mixer a couple of times. It has done a good job for the price. Good starter mixer for video productions.

Sliders and knobs are recessed in the frame of the unit, bit it helps reduce unintended adjustments. Works well for the size and is perfect for small spaces. Bear in mind, if a microphone is to be connected, get a pre-amp, otherwise mic volume will be very low.

This thing is great. No interference noise at all or hum. Bluetooth works great. Couldn't be happier. This mixer accepts stereo inputs, unlike the cheap Behringer one that looks like it accepts stereo, but they are actually Mono channels. I love the fact that it has dual output levels. I used this on a multiple tv set up where we can mix in audio from different sources at different times. (Think 4 different football games playing at once, but you only want to listen to the one that has the most action happening). I have one output going to my stereo receiver and one to a set of headphones. Can control the output levels separately.
