Keyboard Amplifier Reviews - The Best Keyboard Amp

Looking for a Keyboard Amplifier? If you are planning to play in a band or for a gig, start looking at Keyboard Amplifiers.

Inexpensive keyboard instruments come with built-in speakers that are good for learning or to be used as a hobby, but the more professional keyboards and digital pianos require keyboard amps if you want to see their true capabilities. The quality of sound samples used in these digital keyboards/pianos cannot be completely appreciated over normal speakers. Besides, external amps give a lot more power to the sound which can be hear over a large area.

A good pair of headphones or your home stereo system can greatly enhance the sound of your digital keyboard. Though your home stereo system can greatly improve the sound quality of your digital keyboard but it has limitations compared to a Keyboard Amplifier. It is not portable, it is apt only for personal use, but more importantly it is not meant to reproduce faithfully the complete sonic spectrum of a digital keyboard instrument.

A decent keyboard amp is the only option if you intend to perform as part of a gig. Keyboard amps are quite portable and depending on how big the performance venue is, you can choose a model with a suitable wattage. The more the wattage, the louder is its ability to reproduce sound without distortion.

Some Keyboard amplifiers have built-in line-outs. So if you want to pass your keyboard amps output through a mixer, you can easily do that.

Performing in public is what every keyboard player dreams of, and if you have decided to do that gift yourself a decent Keyboard Amplifier.

How To Install A PA System Safely

There are quite a few things to consider when setting up a PA system. If these things are not addressed in the beginning, you will only have problems later. Problems during any type of live performance are never good. The most common problem is ear shattering feedback. This can be a literal headache for the performer and the audience. Here are some other things to consider before you begin.

Room Size - The size of the room will greatly affect the way you should setup your PA system. Different sized rooms have completely different natural reverb and decay. A large room will have more reverb than a smaller room. If your levels are set incorrectly reverb can turn into unwanted feedback. Always test everything before the performance.

You will have to make minor adjustments to your PA system installation depending on the crowd. If the room is large but you have a huge crowd, then your settings that were made while the room was empty will not apply. The crowd has just completely changed the whole layout of the room. You will have to make adjustments.

Room Composition - What is the room made of? Wooden rooms will sound different than glass or metal. The composition of the wall behind the stage is very important. It is a good idea to cover the wall with blankets or anything that will absorb some of the sound. If this is not done, the sound waves will bounce off the wall and come back towards the mixer and this can make things difficult to adjust.

A PA system can be huge or small but they all consist of the same type of parts. You will have your amplifier, a mixing board, speakers and input sources. These can be microphones or instrument cables.

If you are setting up the PA for the very first time at this location, make sure every knob, button or level meter is turned all the way down before you start hooking everything up. This can prevent blown speakers, fuses and ear drums.

Ultimately your speakers should be on the front of the stage pointing out towards the crowd. You should setup the mixing board and power amplifier as far away from the speakers as possible. They should be in the back of the room, opposite the speakers. This will give the sound person the optimum area for fine tuning levels and EQ.

Attach the amp to the mixer and then attach the speakers to the amp. Plug in all of your microphones and cables that will be going into the PA system. Make sure everything is where you want it to be. Double check that all volume levels are all the way down before you power up the PA system.

Turn on the amp first. Wait a few seconds for it to warm up and then power on the mixer. Adjust the gain level on the amp and then adjust the output levels on the mixer. If you did everything properly you should be ready to start adjusting volumes and the EQ. Now you are ready for the show!

will 500w speakers work ok with my 100w output mixer amp?

Ok, I have bought a mixer amp, its this one (cut and paste the link please)

What I need to know is, will these speakers work with it?

http://www.maplin.co.uk/Module.aspx?ModuleNo=220554

They are the same price as the 400w ones that Maplin recommends for the mixer. I am a little confused! I am buying them for small venues and karaokes but it makes sense to me to buy the larger speakers if they are the same price? Of will they blow the mixer amp as it is not powerful enough to run them?

The main issue, over and above the previous answer is IMPEDANCE.

Your Amp will have a stated output impedance and your speakers should have the same input impedance for undistorted sound and maximum efficiency.

It is a good idea to run higher capacity speakers than the amp output when gigging. They last much longer!
