Good keyboard amp?

If you're just playing at home either a good computer speaker system might work (might blow the speakers though, I don't know) or powered monitors are the way to go. Powered monitors are designed for up-close listening... they are very clear up close but the sound does not project very far. Not ideal for gigging. Very ideal for home/studio use. Hope that helps.

A warning about computer speakers: they're consumer-grade, and tend to colour the sound somewhat by design. It matters much less for keyboard playing than for mixing a recording, but don't be surprised if you plug your keyboard into an amp someday and it sounds slightly different in a bad way (a sound may have too much bass, not enough treble, etc.) Still, if you end up as the keyboard player in a band, that kind of subtlety probably won't be noticed by anyone but you.

That said, this is a pretty subtle thing, and shouldn't dissuade you from using computer speakers with a 1/8" female to 1/4" male adapter to save some money.

Application is everything when amplifying keyboards.

If you're playing at home, good quality monitors will be fine. At a rehearsal or gig situation, you have to look at the "range of sounds" you'll be using. Sweeping synth or fat bass patches, lower register B3 sounds tend to eat most run of the mill keyboard amps alive.

I've found that the majority of dedicated keyboard amps simply aren't up to the task. My solution was the Mackie SRM450's for my personal stage monitors (and for larger applications, or more low end, I add the SW1501 subwoofers). I use a stereo 8 channel line mixer and send the mains to the FOH, and the mon/effect send to my stage mix. Works like a charm and doesn't color the sound like some amps.

The downside? Expense and multiple cabinets (for a stereo rig).

If I had to use only one dedicated integrated keyboard amp, I found the Traynor K4 a pretty good choice and preferred it to the Roland's, but the Roland's are fine too.

behringer all the way dude

Behringer all the way. i got the 150 watt version, and it is awsome. but no matter what amp u get, u need a bandana..... wait WHAt a bandana? that has noting to do with keyboards!:eek: wrap it around the handle on the top. if you dont the amp will rip your hand to shreads! well... not litterally, but the hard rubber/plastic stuff hurts your hands.

Behringer is not a good choice. Poor build quality, stuff breaks on them quite often. A friend of mine has a Behringer... don't do it. You get what you pay for; they are cheap for a reason.

Yeah, I've had nothing but trouble from Behringer, ranging from a FoH digital compressor that approximates everything to what sounds like 128kbps (when it works) and a mixer which literally blew up...

ok.....I have to tell you all somethying about keyboard amps.................BURN THEM ALL....eveyone has it in their head that because the guitarist has an amp so too must the keyboard player.....look at any well know player they dont use amps....the use monitors, their is one big reason behind this, must keyboards are designed to put out a stereo signal....this requires two speakers.....simple as

Monitors are harder to position correctly at a gig, and if you're not running into the house mixer in stereo, stereo monitors don't make any difference to anyone else. My personal preference is to get a sound as close as possible to what people in the audience would hear.

Maybe I've missed something here, but no-one seems to have mentioned frequency
response.

The range of an 88-note piano/keyboard starts at 27.5Hz.
Hz = cycles [or vibrations, if you like] per second.
The lowest bass note (A1) is 27.5Hz, and the top note (C88) sounds at 4186Hz.

What you find with guitar amps/speakers, for example, is that the very lowest frequencies are not catered for simply because the guitar does not play notes as low as that.
If you look at the specs of many amps the lower frequencies may only go down to 50Hz -
this means that the whole of the bottom octave on an 88-note keyboard is not covered
(the 11th note - G11 - sounds at 49Hz)

Now to the treble end.
You may think that because the top note (C88) is 4186Hz, an amp that exceeds this would be ok.
Wrong!

The thing that gives any stringed instrument it's 'character' is the presence of harmonics - see examples shown here.

u11l4d1.gif
u11l4d3.gif
u11l4d4.gif



Illustrated are the first three harmonics, but this goes all the way up to 16.
Beyond that the audibility is negligible.

Each harmonic has a higher frequency than the one that preceded it, so high-end frequency response is equally as important as the low-end in order to ensure sound clarity and 'tone'.

Most adults (your hearing range decreases as you get older) cannot hear frequencies above about 16-18,000Hz, with a maximum of up to about 23,000Hz (in the case of a good piano-tuner, for example!).
So an amp/speaker combo exceeding this should cover the bases. 18-20,000Hz is usual for most decent quality systems.
Incidentally, a dog hears up to about 45,000Hz, a cat 64,000Hz, a mouse 91,000Hz and a porpoise
a whopping 123,000Hz!

I hope this is of some use!

Speaking as a physicist - Fantastic explanation! I hadn't thought of mentioning it as checking frequency response is an unconscious thing for me - if it's not 18-20k, I ignore it generally.

HOw on earth do you mean they are harder to position...... most are wedge shaped so you just leave one on the ground either side of you.why on earth would you not run into the house mix....thats just silly.....and if you didnt run into the house mix stero monitors woulsd make a big difference.....because your hearing it in STERO..... ie. all your panned efffects and voice can be heard a bigger sound.....and i think frequence response goes without saying

.....and i think frequence response goes without saying[/quote said:
The point of forums such as this is to:

a) Ask questions in order to find info.

It "goes without saying" that if you ask a question, it is because you don't already possess such knowledge.

b) Reply to questions to which you do know the answer.

If you just assume that everyone knows the stuff that you yourself take for granted,
then no-one becomes any the wiser.

In this particular instance, other readers may not be aware of the importance of 'frequence' (sic) response.

I myself know countless people who think a loudspeaker is 'just a loudspeaker', that they're all the same,
and have no idea why you should spend £500 when you could get them in the local discount store for £12.99.

Yes, you may know as much about it as I do, but the point is that other
people reading these posts may not.

Nothing smart about that - it's just a courtesy to folks who want info.

Yamaha Stagepass 300 works for me

I was using some Alesis monitors but when I started performing around town needed a portable system and went with the Yamaha Stagepass 300. For me the sound is very good pretty much across the board, and teh Stagepass includes a mixer with 4 XLR inputs. It has been a very good solution for me, your results may be different.

About monitors: I was thinking a standard pair of studio monitors, not a wedge-shaped stage monitor. That said, I haven't had the opportunity to play out of one directly (when I play at church, the monitors on stage are used for a custom mix for each performer); how are they better than, say, a Roland KC-350 that's not built to colour the sound in the same way a guitarist would?

As for not running into the house mix, read what I said again. I was talking about not running into the house *in stereo* (i.e. running in mono).

May I politely suggest that your good advice will come across better if you correct people who have made technical mistakes in a less antagonistic manner?
