BOMGEProfessional Audio Mixer, Sound Board Mixing Console with 4 Channel Digital USB Bluetooth Echo Delay Effect, Input 48V Phantom Power Stereo DJ Mixers for Recording, Live Streaming, Podcasting

For $25, you get a lot of features for the money. However, it is a little noisy.

I was quiet disappointed with this mixer. Having a decently versatile sound board with USB power would be great for portability. The specs look fantastic, but unfortunately there are some significant issues that make it unusable in any real audio workflow. I knew it wouldn't be as good as my name brand board, but it's got some issues that make it a deal killer for me.Issue #1 - USB connectivity: The description says that it has USB C connectivity, this is inaccurate. There is USB Micro on the back and USB-A on the top. A USB micro port isn't the reason this is an issue though, the issue is that it is for power-only. Even though there is a graphic indicating a laptop over the label "USB Audio", the only USB audio is from the USB-A port in the form of a flash drive or a card reader. Windows does not detect this as an audio device, I'd consider the possibility of a driver issue, but there's not even a new device that shows up anywhere in the Device Manager. There's no USB audio device here.Issue #2 - Mislabeled things: The Play/Pause button is the back button, the back button is the forward button and the forward button is the Play/Pause button. The "Record" mode has an "FM" indicator on the screen which makes no sense because there is no FM radio. There is a "REC" label with a dot above the mode/BT button, but no button appears to actually start recording.Issue #3 - Audio quality - The Mic pre-amp is VERY low. That might be okay, but you can't feed an amplifier with it because there is white noise that present even when all inputs are at zero. The MP3 audio quality is better, it's louder than the white noise anyway, but it distorts long before the "CLIP" indicator lights (even before the one and only SIG indicator lights). Feeding it a clean stereo signal via the RCA L/R connectors is also just okay; it's not bad until you realize how much dynamic range is lost in the low and high end.The Bluetooth audio is okay, but it doesn't connect as a input device to the phone, just an output device "headphones" which means that you can't even use it as output for call audio.The effects are limited to a delay and repeat echo effect. It works, though it's not particularly interesting.The only reason I'm not giving this an even lower rating is that this might be useful as a toy for kids to learn what a sound board is and play around. It should not be presented as professional audio gear. It's not going to produce a clean recording and if you have any ear for high quality sound you won't want it anywhere near your audio chain. I might use as a BT device, but there are much better solutions for that. A lot could be forgiven for the sake of USB power if the audio was just low, but it's not clean enough to do anything with so there are limited situations where the portability makes up for that. Maybe low budget karaoke, a cheaper mic might actually sound better than my good Mic and the white noise might not be as noticeable.

I wouldn't call this Professional as the item description does. The quality of the board and knobs is ok but not good enough to call professional. This has a use for basic things though and in some situations having a very compact basic mixer is all that's really needed. For instance, at a karaoke party if you need a couple of microphones and some music this will likely be just fine. I wouldn't recommend doing any serious recording and mixing with this. It would be nice if the main outputs had a bit more flexibility but you can make it work with the right cords.

This profeesional audio mixer has some really capable features; especially for under $100. It has 4 channels which is more than enough for what I'm utilizing it for; streaming. It has some echo and delay settings which are fun to play around with and seem to work pretty well. I've taken this to a few gigs including the studio and so far it's been really reliable; no issues and it's very easy to use. The only issue I have is that sometimes the knobs are a litte sensitive and I'll accidentally switch modes which can be frustrating to recovery from BOA especially while live 😅 A small complaint but worth mentioning. Overall I'm very impressed with this mixing console and have already recommended it to some of my sound tech friends who were also impressed with the quality given the price point.

This is a tough one to review, because on one hand, I want to like it for the price of $30 (I got this for free from Amazon Vine program, but have various mics and audio equipment gear that I'm comparing it to). But it really falls short in being anything functional for most.LABELSAs mentioned, the labels are improperly labeled. I noticed right away that the "2/3" label at the top is off. The input numbers (1-4) are supposed to correspond to the knobs at the bottom, with Mic 1 being controlled by Gain 1 (the whole column, but for naming purposes), Mic 2 goes to Gain 2, etc. "2/3" should actually be 3/4, seeing as it is controlled by the 3/4 column. The media buttons are also improperly labelled, with the actual arrangement being Back, Forward, Play.USB CONNECTIVITYThe USB connectivity also leaves a lot to be desired. The USB mini in the back is used primarily as a power source, leaving only the USB-A port on the front as an audio source. But that is only for audio input, not output. For me this presents a couple issues because 1) Ideally I would love to use this to record INTO my computer, but apparently not through USB; and 2) If I do connect USB audio into the device, the cable now hangs around the middle of the device, as opposed to running through the top as with all the other input devices.EQIn terms of EQ (High and Low), I guess it works. It really is a simple "make highs/lows louder/quieter" than something used to actually isolate certain frequencies. It's nice if you want to EQ your music while listening to Youtube, hahaha. I was able to make some songs hit a bit harder with a bit of EQ-ing, which is nice.SIG/CLIP LIGHTSEh. Not sure why there's two to each since they both light up at the same time, as opposed to LED 1 lighting up completely and then LED dimming up and down as the signal increases. But instead, it just both turn on. And even though, the signal is coming through (since I am listening to it) but the light won't necessarily show.EFFECTSYou have delay and what I thought was reverb but I guess is meant to be repeat? Either way...as someone else state "It works, though it's not particularly interesting."OVERALLFor $30, this is a pretty cool device to use for basic things. As an uncle, I like to show my nieces and nephews my gear and so this would be cool to use instead of my higher end stuff.And I can totally see myself using this at small house party where I can just toss this in my bag, hook up my iphone, then EQ each song to make it sound decent on some small speakers. I could even hook up a basic mic to the second channel and stuff and begin announcing when people need to leave my home.But for actually recording and mixing...eh. No.
