I have run in stereo on my rig since 1973. Yep I'm old. I've also "been around" a bit. I was looking for a smaller rig to use for solo work. I've got a very small 10 channel mixer and thought I look at some small powered monitors/speakers instead of using the extremely heavy JBL floor cab that weigh around 85 lbs. each. They do rock though !! Anyway the powered monitor I was looking at went from around 500.00 and up. Then I strolled into the keyboard area while waiting and discovered this little gem. The k1800FX (180 watts with a 12" and a horn) comes in slightly over 40 lbs. PLUS it has the added features of a 4 channel mixer (in stereo) and input #1 also has a Lo-Z mic input. That leaves 3 channels (3 stereo with 6 inputs). A nice graphic EQ let's me balance the sound to my taste (which is picky just like everyone else, I want ME to like the sound). Amp has a "Link" 1/4" out to send to another amp (any amp) and sends it one of the stereo outputs from the mains turning your rig into stereo. Of course using only the amp by itself will result in a mono mix. After doing my homework researching this item and reading lots of reviews on many different sites, with a couple of people mentioned buzzing problems (which were repairable - it happens to a lot of amps, not just this model) here's what I decided. At half the weight of my previous rig (not including the power amps, etc) and at a very reasonable cost compared to powered monitors, I bought 2 of these to run in stereo. Now, here's my reasoning on another level. IF and I say if one should need repair I can still get through a gig with only one as each has a mixer built in.!.! And here's the best part. It cost me HALF as much. Wow, is that cool or what? Enjoy, I am... Peace.

I was initially very pleased with my K1800FX, and it worked perfectly at rehearsals and small gigs, but when my band started playing larger gigs, and I needed to bring the volume up, it started cutting out on me completely. I called support, and they said it sounded like my amp was going into "thermal shutoff" mode, where it shuts down the amp to protect it when it gets hot. I was playing loud, but didn't have the volumes up all the way - there is no way this amp should have done that. My 150 watt Peavey KB300 never did that. My recommendation - it's perfect for rehearsals, but I wouldn't trust it at a gig where you'll be playing loud with a band and cranking up the volume.

I have two and am very pleased

By 

from Bastrop Tx

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

Purchased one about three months ago and liked it enough to buy another so I could play in stereo. They sound great with my Mininova synth and my Boss RC505 Loop station. Loud enough to rock the neighborhood and have the popo show up! I have had no problems.

Good Value for the $$.

By 

from Houston, TX

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

I replaced a Peavey KB4 with this Behringer K1800FX. The sound of the 1800 is a lot better, and in a much smaller package. Tighter bass, better quality highs. On the plus side, it has microphone and 1/4" inputs. It also as XLR outs, which are great for connecting to a PA. The FX are a nice bonus, but I don't really use them much. I typically use it as a self-monitor for large gigs, and an all-in-one PA for small gigs. (I play keys, acoustic guitar, and sing.) On the negative side, it is REALLY heavy. But, at least it is small enough to fit in a car trunk. Another downside is that the stem of each knob is made out of plastic, not metal. You have to be really careful not to bump the knobs on the top of the amp or they will break at the stem. Overall, for the price, it's a great amp. I would get one again if I needed to.

little big amp

By 

from Santa Paula, Ca

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

I wanted a smaller amp cause I'm tired of lugging around the heavy stuff. A friend told me about the berringer1800, smaller but lots of power. So I gave it a try and am very pleased. It's much lighter than my old Pevey and not as powerful, but for clubs it has kicked bigtime. I get great clear tones on my pianos and it's strong enough for the organ sounds as well. I'm considering getting another for the larger gigs and piggy backing them.

Not loud

By 

from phoenix

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

This is not loud by any standards, watt rating is way too generous. I have a Crate KX-80 and it's quite a bit louder than this, rated at 80 watts, but it's also heavier. sounds fine otherwise. i haven't used much of the "effects"

Volume.

By 

from Duluth, GA

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

When I got this amp, I was pleased with its sound. The sound quality is really good, and I could sit and play with the effects for hours. My only initial problem was with its volume. Essentially, this is an over-sized practice amp considering how quiet it is. When I brought it to band practice, my guitarist was shocked to find that the volume I was playing at was as loud as it gets. The amp was near 10, and he assumed it was at maybe 2 or 3. I ended up returning this and getting a Roland KC-350, which I'm pleased with so far.

Good for a small gig

By 

from alabama

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

This is a great amp if you are playing in a small acoustic band. It works well for me and i am in a 9 person jazz band. I haven't really used the effects but having 4 inputs is great. Warning: This is NOT a "loud" amp. It is fine if you don't want to drown everyone else out; however, if you want to "rock the house" this is not the amp for you. I have mine set at 3/4 most of the time. All in all, i would suggest this amp to any pianist in a small band who wants to hold his own but not blow the audience away.

Perfect Amp

By 

from chicago

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

i got this amp about 1 year ago and it has been awesome. it has a powerful 12" woofer that gets the job done and the 1" tweeters really nail those high pitches. i use this amp for an electronic drumset and it always works perfectly. i play in a band and we all plug into this amp which just shows how incredibly powerful this amp is. i would recommend this amp to anyone who needs a good multi-tasking amp for a band or for just using it on your own.

After long search,I found it !

By 

from Randolph, MA.

Comments about Behringer ULTRATONE K1800FX Keyboard Amp/PA System:

I had been looking for a long time for a practice amp worthy of the sound I require,and I finally found it. O.K., now let me explain. I am a guitarist,and I really didn't want to spend big bucks on an amp for practice purposes. The smaller modeling amps just didn't sound that great. I have been using a Boss Micro BR,and the COSM sounds that it comes with blow away anything I was hearing on these modeling amps. I was poking around at GC in the Keyboard Dept. when I came across this mighty little beast. Aha! I could run my Boss Micro BR thru it,and enjoy all the on board COSM sounds it has to offer. The bonuses were that it has 4 channels,so I could run a Mic on another channel,play a CD thru,a Drum machine, and even play the Harp thru it. I had never considered a PA/Keyboard amp until I found this marvel. It even has 99 Built in digital effects that can be assigned to each channel. This has got it all, especially if you're looking to do evrything yourself as I do,in the privacy of my home. It certainly has enough power to do a small gig. I can't say enough about it. I am completly satisfied. And oh, did I mention it's loud too ! As with anything you purchase, i may be right for you, or it may not be for you. But this Gem is exactly what the doctor ordered.
