Personal Monitor Solution

Have you ever dealt with a "more me in the mix" musician? Well, the Behringer Micromon MA400 monitor headphone amplifier may be just the perfect solution. Not only will this headphone amp take a mixer input, but it is also designed to pass through the signal of an XLR equipped microphone, and both signals have level controls. You can let your singer or other musician dial in as much "me" as they want, without affecting the rest of the band. It will even pass through the 48V phantom power for condenser microphones. This is perfect for studio or "silent practicing" through a mixer. The MA400 has outputs for both 1/4" and 1/8" headphone plugs. Let your band have control over their mixes with the Behringer Micromon MA400.

Works Great

I used a couple of other much more expensive models, but this does the job as well. Put the 80 dollars or so you save into a new pedal!

Awesome Product

I bought this for my new in-ear monitors and it is awesome!! It gives me great control of my monitor at my drum set. Highly recommend this product.

Does its job well and at a great price!

My church is transitioning to in-ear monitors and we just had our first practice with them this morning. The sound quality of this little box is amazing. I really didn't expect my guitar to sound as good as it sounds through a $20 piece of equipment. I was so impressed, I bought four MicroMON MA400s -- one for each guitarist and one for our keyboardist. Our bassist used one today, so I may have to buy another one for him. This little box gives our worship team's musicians the flexibility to increase or decrease (ha!) their instrument's volume without blowing away everyone else's ears in the process. Also, it's so small, you can literally put it anywhere and it won't be an obstruction or a distraction. I definitely recommend this to any band or worship team who can't afford digital in-ear monitoring. The saying, "You get what you pay for" doesn't apply here. The MicroMON MA400 is an absolute steal!

THIS THING IS GREAT!!! If you're a singer, bass or guitar player and you're sick of not listening to your instrument, grab your monitor line, stick in this thing, pass your mic through it and VIOLA!!! HEAR YOURSELF CLEARLY and without bugging no one. I mean i'm trying to find a negative, but there isn't. The sound thru it and out of it is crispy clean and it's really cheap compared to the next product that does the same thing. Just buy it and you won't regret it.

GREAT Value!

These things are a great little value! We wanted to get rid of our stage monitors, and give our musicians and singers an earphone monitor system without spending thousands of dollars on fancy full-featured IEM systems (we'd like to have those features, but not for those prices). Using these, we were able to give each person volume control over their own monitor, plus volume control over their own mic/instrument in their earphones. It's not as nice as a fully individually custom monitor mix, but it gives each person the most basic controls they need most often for literally about 1/10th of the price. They work great, sound great, and for the price, have great features and quality (and that's coming from someone who's not Behringer's biggest fan). The only thing I'd like to see improved is some sort of mounting system. It was rather difficult to find a way to mount these to a mic stand so users would have easy access to make adjustments with the two tiny screw holes on the bottom; difficult, and not as secure as it should be.
