BehringerMICROMON MA400 Ultra-Compact Monitor Headphone Amplifier, Silver

I'm a professional musician, I do guitar and lead vocals in a full band and in acoustic solo shows. I really wanted in-ear monitors. I got some cheap in-ear monitors, but even though they have a volume control, they sometimes do not work with certain PA systems, or they just don't have enough power to give me enough volume.I bought this product to try to solve that issue, and it's working. It adds additional power and volume to in-ear monitor systems. You can run a quarter inch instrument cable from the PA system's monitor outputs, line out, or even headphone out depending on the setup. Plug that cable into the monitor input on the behringer thingy, then plug your in-ear monitors or regular headphones into the behringer thingy. You will now have more power and volume, and an additional volume control so that you can hear the monitor mix from the pa.It's always hardest to hear the vocals, so there is an additional option you can use separately or together with the monitor mix. You can plug your vocal mic into the behringer thingy, then plug the behringer thingy into the mic input of the PA system. The PA system will just be getting your microphone signal like it normally would. No fuss for the sound guy. But, you can then hear your vocals at a much louder level that you can turn up and turn down.If you do it this way, you can hear just your vocals OR just the full PA mix OR both, and you can control their volume levels separately.So if you're looking to get in-ear monitors, also get this product so that you can have more power and control. In-ear monitors by themselves might not be enough unless you get really high-end expensive ones. With this product, you can get cheap ones or you can just use regular headphones. I recommend Bluetooth headphones or actual wireless in-ear monitors.

If you use a Click track or a metronome then this is a vital part of your set. My brother is a killer drummer who has been recognized by Guitar Center, and also he played behind Christian Artist Eddie James. I bought him one of these for his birthday cause he complained about how he never could get a good mix with his headphones. I saw this on Amazon and decided to try it. BEST PURCHASE EVER!!!!! Now when he goes and plays at different venues all he does is require them to send him an even mix of the music and he can control how loud the click track is as well as the mix. It doesn't stop there, it works as a DI box as well, he can send the track to the mixer and they can separately control it to the house or other mixes on stage. It doesn't stop there either, this Bad Johnson has some sort of ground lift or noise cancelation technology in it. I'm not sure what it is cause I've never just looked at it closely enough, but most the time when something has a complete loop through the system you'll get some sort of buzz, hum, squeal, or echo, well this thing completely eliminates that problem, it also cancels the click track from coming back through.I'm a pianist and sometimes I use my laptop to add certain sounds to accompany what I play through Midi, I'm going to buy one of these to hear my own mix to hear it cleaner through my headphones, I'm also thinking about getting one for everyone in our worship team in our church. These things are handy and you can always find a place for them. My brother brings this thing along before he brings his custom set of cymbals, snare, or foot. If you are reading this, just go ahead and buy it, its worth 3x more than what its priced for....believe me.

Decent problem solving device for getting a little more volume from your personal mic. 2 downsides. Not loud enough for big rooms and it would be nice to have a way to attach it to a mic stand. I zip tied it to my mic stand and bought a 3' mic cable and a 1/4 phone to the monitor output from the board. Works OK but does not look so good. I like my monitor and mic volume close enough to adjust.

I bought this micro mixer for ~20, and it is far better than the price suggests. I'm very happy with the purchase. You will be surprised at how small it is. I actually wish it was bigger... First thing I did after I tested it out, was to take it apart. Inside, you will find very well made circuit boards, with two tiny little surface mount opamps. The connectors are good quality, the metal case is extraordinarily good quality, the finish and all! The only thing I don't like is the knobs on the potentiometers. As you turn them, they rub on the metal case a bit, and it makes it feel cheap. BUT THAT IS IT.Now, the sound quality is fine. I noticed nothing significant about the quality of sound, except that is not exceptionally powerful. Listening to myself on headphones using a sure SM-58 dynamic mic, I must turn the mic volume control all the way up just to get it 90% of what I would like.I do wish it had more amplification. Personally, I think wherever you have a dedicated amplifier driving headphones, it ought to be perfectly capable of blowing up any pair of headphones, if it is needed. I like to have power in reserve. Headroom, I think it's called. This thing needs it.If you're curious, the Mic in and Mic thru connections are wired in parallel... so this box will have zero impact on your sound being recorded, no matter how fancy a microphone you are using. I'm unsure how well it will work with condenser mics. I think they put out a higher level signal... might make things better.And, it needs a power switch. It doesn't hurt to leave it on, because it doesn't get warm at all, and there's nothing going to wear out, but it's still just one of those things... got to have a switch...
