"Great Little Amp"
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
This little amp packs a punch. Big sound in a little footprint. We have been running my three keyboards direct through the PA and getting the sound back on stage through front and a personal monitor. This amp lets me hear myself more clearly, control my stage volume and keep me lower in the PA mix when we play smaller clubs. I'm also able to run my sax mike directly to the amp to take advantage of the effects and removing the extra phantom power supply connection. We then run the amp output to the PA so the sound man can give me a boost for solos and make sure I fit into the mix while allowing the vocals to shine. Best investment I've made in my rig in some time.

I'm just getting into playing in a 4 piece blues/ geezer rock / jazz band, so I can't say how it does in a gig setting, but it seems plenty lound enough. A little bit of hissing when everything's way up, but we don't want to be the world's loudest band. Nice it has a mic input for practice since we didn't have a PA right away. I have an old Korg SP100 (getting ready to get an SV-1). I'm confident it will be fine for that as well.

"Step aside Peavey and Roland!!"
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
Don't think that I will be needing another amp for my purposes
Sound
The amp has everything that I need to play the gigs that I do.It has the Roland amps
beat hands down.I don't need the effects as much as I thought that I would for my keyboard,
but they are very nice for the acoustic guitar that I play on my Saturday afternoon gigs.
Features
The EQ has a very effective setup for the rooms that I play in.For such a little amp it
does pack a punch.I like the fact that I can go to a gig with just that amp and do everything
with my mic.,my keyboard and my midi setup.
Ease of Use
The manual gave a few pointers,for the most part that wasn't even necessary.It was very
easy to use out of the box.I had to go online and get the effects data,but that isn't a big deal.
Quality
This amp seems well made to me.I wouldn't be afraid to use it on the road.It would be
nice to have a dust cover for it though.
Value
Best bang for the buck!!
Manufacturer Support
I have a Behringer eq module that I have been using for years.I had to get some
information on how to use the real time analyzer once and they were very helpful in
telling me how to get the best out of the module in a noisy room.Never needed any service
on this product.

Nice looking well made unit

"Best Keyboard Amp in its price range."
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
I've had this amp for 4 months. No Problems. Use it LOUD as my keyboard amp to gig with a rock band. Use it as a 4 channel PA with a guitar player for "coffee house" kind of set-up (piano, electro-acoustic guitar, 2 mic'd voices). It's a great general purpose keyboard amp.
Sound
The overall sound is very good. It tends to be a little bassy but that can be adjusted with the on-board graphic equalizer. The sound is clean even when playing at full volume. One possible drawback is that at full volume it produces a noticable hiss when it's sitting idle. Great amp/PA for a solo performer in a smaller venue. Acceptable for a keyboard playing in a (rock) band at a smallish club.
Features
There are 4 stereo inputs, one of these also has a microphone input with it - pretty good for a multi-keyboard set-up. It has a headphone output with it's own independant volume that doesn't cut off the main speakers when you plug in a set of headphones. It has a stereo "line in" that can be used to connect and play your iPod or CD player through. The graphic equalizer if OK - it does as good a job as a three knob (treble-mid-bass) system. It also has a stero link that is supposed to connect to another amp and get true stereo - but I haven't tried doing that since I only have one of these amps. It claims to have 100 digital effects - well, technically it does but they count every different intensity of tremelo as one of the effects. This means that there are really only a handful of effects (Tremelo, Chorus, Phaser and some combinations like Chorus+Phaser. The effects aren't bad but I don't have much use for them. Missing from the effects is a decent "Rotory" spin
Ease of Use
It's a pretty standard 4 channel amp. Not very difficult to use.
Quality
For the price this little baby is great. I've listened to it side by side with comparable Roland and Pevey keyboard amps. The Behringer sounded MUCH better than the slightly higher priced Pevey. It sounded a little better (particularly at high volume) than the Roland which cost twice as much. Personally, if I wanted to spend $500 on a keyboard amp, I'd buy 2 of these over the one Roland, any day.
Value
This is a great keyboard amp for the price. There are better amps out there but they cost at least 3 times as much as this one. This is one of the best keyboard amps under $500 US - and it actually lists for only $250 US.
Manufacturer Support
I haven't needed to contact Behringer about anything so I really can't say much about their support. The users manual is a little slim and wanting. The list of digital effects is not in the manual and must be obtained online.
The Wow Factor
I'd certainly buy it again if this one broke. I'm seriously considering buying a second to get true stereo. Looks-wise, Behrenger, Roland, and Pevey all look pretty much like the same stubby black keyboard amp

"Best Amp For Your Money"
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
My Behringer K1800FX Ultratone Keyboard Amp sounds really great. I've put 2 keyboards and a mic and it showed no sign of bogging down. I previously had the Roland KC 550 which is a very good and powerful amp but way more expensive with less control and effects. My dad has the Behringer with the 15" which is much more powerful than mine. Live gigs on stage the bigger amp was rarely turned more than half way , Whereas my smaller one I'm usually on 3/4 power . But I use my amp mainly as a personal monitor and serves the purpose I intended to. Definately will stick with Behringer in the future for keyboard amp.

I
Sound
Great sound. Buy two, and you could have a respectable home stereo when you
aren't using them for gigs.
Features
A cover would have been a nice option for when it's raining out.
Ease of Use
It better be easy to get good sound, as the "manual" is an example of stretching the
term to the breaking point.
Quality
Built like a very high end unit.
Value
I tried Roland amps, every model, several years ago, and they ALL rattled (was told this was "normal!") and the cheapest one cost nearly twice the $. The sound was also inferior. This amp is EASILY the best keyboard amp buy I have seen. (OK, it does come with a giant sucking sound, if you know what I mean.)
Manufacturer Support
Called Behringer with several questions and the guy didn't seem very knowledgeable at all.
He did say that phantom power would take care of the mic level issue, but no explanation on why this is pretty much unusable without it.
The Wow Factor
Excellent compact design, feels extremely solid and is good looking.

Verified Customer

I purchased this amp on 7/9/2012 received it on 7/10/2012 quick right ? i thaught so, anyway I've been looking for an amp with the big sound without the big price, this is it.
I set the amp up with the Yamaha YPG-235 keyboard I ordered at thed same time I was surprised at the sound and quality. I play Gospel music and this fits right in to what I play. I like the idea that I can set up the sound to my liking and have full control. I also play out as a solo act and this is the right amp for me, Keyboard, PA, all in one now I am looking to get another one soon for that stereo effect when I play live. Overall Great Little Amp, and the value is well worth it for the price and you can even pay as you play what more can you ask for.
If your looking for a real nice sounding amp at a real good price? try this one full of features for your aplications and needs GET THIS ONE YOU WON'T BE SORRY!!!.

"Great amp!"
Bought it second hand for just $100. For my Keyboard setup (Roland G-1000, and Korg Triton). Works near flawlessly despite being in well used condition. The only small issue it has is the headphone jack is a bit finicky, and the Right headphone speaker sounds don't come in without the plug being jiggled. This was tested with multiple headphones with the same result. It's a relatively simple fix that will only take a few minutes at best.Overall I have no complaints about this amp.

"Just bought this smoking amp. I found a way to get to use more than 45 watts per input"
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
I really love this amp. I owned the KT108 15 watt ultratone for practice. My new Yamaha MX49 based on the awesome motiff series needed some speakers.
So I sold my Behringer KT 108. Bought this big boy. Woah. 180 watts of sheer sound. Some very smart dude figured out that because there are 4 channels, that each channel gets 45 watt per input.
Well. I wanted to get to use at least 90 watts per instrument.
My plan was to plug in my dynamic microphone, an Audix Om-2 and my synth.
That way I could hear my vocals on stage with my modern rock group. I find just using the PA limits being able to cut through the band's mix.
When I found out I would only get 45 watts per channel, I got out my electronics 1/4 to xlr, some female 1/4 to two male 1/4.
If you want to get 90 watts per instrument, you do have the option to create a stereo effect.
So here is how to get 90 watts, and two instruments using all 4 inputs.
-Get a 1/4 female input and two 1/4 male inputs. (They come stereo and mono for female and mono only for male)
-Get xlr female to 1/4 male
Grab your dynamic microphone and plug the xlr female into the bottom of your dynamic microphone which is xlr male.
They match and will click together.
Then plug your 1/4 male at the other end into a 1/4 female which is attached to two male 1/4 inch.
Hosa and many cable r us companies have all you need. Simply type a short description. The net will find you what your looking for.
Then plug one 1/4 male into channel one, left mono. And then plug the other 1/4 male into the right channel two. It doesnt really matter which one left or right you plug into, just plug the second 1/4 into the second set of inputs.
Now you microphone is being powered by two engines with 45 watts each.
That can be done for a synth even easier. My Yamaha MX 49 has a left and right 1/4 out put.
So I don't even need to buy another set of xlr female to 1/4 male, and 1/4 female - two 1/4 males.
So there you have it.
Maybe another musician who likes some electronics might even know how to rig it so its in quad stereo for one instruement.

I had the amp (2) weeks before I bought a Roland KC-350 that sounds much better with a lot more power.
If lost or stolen I would not get another Behringer.
Sound
Clear sound with good highs. Bass is a little weak. Hisses when the volume is cranked which most people will need to do.

The EQ is the the best with the use of the shape sound button. I don't need the special effects. I am a keyboard/midi accordion player.
Ease of Use
The sound is ok. I don't feel this amp produces great sounds.

The amp is well made but a bit heavy for its size. I don't know how reliable it will be over time.

This amp has awesome features and sounds great but is not loud enough as many people have stated. I love the 4 channels and effects and sounds pretty clean. I got mine used for $140 and will prob just use it at home or maybe for light practice so it works for me. However when shutting it off I hear a crackling noise which can't be good. Not sure how well built it is but hopefully it does not konk out on me.

Quality
I was warned about purchasing a Behringer amp...The word is that they blow up under preasure. I purchased several Behringer outboard products in the past and were satisfied with them. Therefore, i figured those warnings were subjective. WRONG!!! I took my "Brand New" Ultratone K1800-Fx out on a gig yesterday, however, 20 minutes into my performance the amp started making a horrible buzzing and crackling noise. I had to keep shutting it on and off...eventually i could not continue with an auditorium filled with people gathered for a birthday party.
I was performing solo using backing tracks played through my laptop, Vocal mic and my acoustic guitar. I am now embarrased and humiliated for spoiling what had started out being a fun party.
My confidence is "shot" when it comes to risking using another Behringer amp.

Could have been great if the unit held up.

I've owned this amp for about 6 months. I work a lot in the nyc area. It was light, specs looked good, price was a gamble. oh well...
I do not recommend this amp to the discerning ear.
Sound
This is the worst of all. I run a triton and a fantom thru it. It just sounds terrible. No matter what I do with the eq it does not change the fact that this amp does not sound good, which is the ultimate justification for buying an amp. I a/b it with the roland 350 (which too has its faults) and there is no comparison. Too bad, considering the specs...

I got this amp about a year ago, this amp really sucks, the box said that it was 300 watts of power. I got the amp because of the price, I had a older model Roland Kc 550but someone els blew it out so I went with the Behringer. The Behringer blew out after 6 months so I took it back and got another Behringer again right out of the box and this amp blew out again, so I took it back and paid the difference and went back to the Roland KC 550 the best key board amp.

"Amp lacks power"
I chose this product for the power ratings, its options such as eq and effects, and light weight. Unfortunately, its lack of power may require that I replace it sooner than later.
Sound
The sound is clear and bright compared to my Roland KC 350. However, the KF1800 has no power. When I take it out on a gig, I have to play it at 3/4 volume and at some points it is not even effective as a monitor. If I try to get it any louder it breaks up. If you are going to use it with a medium to loud volume band forget it, unless your keyboard has a really high output volume. It has half the power of my Roland although the Roland is only rated at 120 watts.
Features
The bells and whistles on the amp are good.
Quality
The amp is a new amp. I am taking it in for warranty service, in case there is a problem internally causing it to lack power. Although, I have read from reviewers on other sites that they also thought it lacked power.
Value
If the amp were advertised at 60 watts not 180 watts, then you would know what you are getting.
Manufacturer Support
Support seems to be responsive so far. However, if they overrated the power of the amp, there is nothing support can do about it.
