In a hurry? Here are our top picks..

About Keyboard Amplifiers

An amplifier for your keyboard is not going to be as fancy as a regular guitar amp. The whole job of the keyboard amp is to raise the volume of the keyboard so that it can be heard over the other instruments. Digital keyboards come with their own speakers, but they don’t have enough wattage most of the time to be heard in a larger venue such as a club. This is why you need a keyboard amplifier. The right amp will help improve your sound and tone.

What do You Need the Amp For?

Where you buy your amplifier, you have to determine what you’re going to use it for. If you’re playing at home most of the time, you can use the speakers through your keyboard itself, and there is no need for an amplifier. This is different from a regular electric guitar where you need an amplifier to hear yourself play. If you plan on playing on stage, then you will need an amplifier so people in the venue can hear you. In some cases, you can also use the system at the venue to be heard. There is no real reason to use an amp at home unless you are looking for more volume out of your musical instrument. Your keyboard should give you enough volume out of the speakers as it is.

Keyboard Amp Not Guitar Amp

You can’t use a regular guitar amp for your keyboard. It is not going to sound the same. In fact, in many cases, it might not work at all. The knobs and switches on a guitar amp are designed to enhance the sound of an electric guitar and not other instruments. This is why the sound is not going to be the same. You need an amplifier dedicated to the keyboard itself. Your instrument needs a broader frequency range. There are different tones and synthesized sounds that guitar amplifiers can’t recreate properly. Some amps allow you to use both electric guitars and keyboards, but check to ensure that this is possible as not all of them are going to allow this. An amp that can only accommodate guitars won’t help you.

Features and Specs for your Keyboard Amplifier

There are several specifications and features that you should be looking for when purchasing an amplifier dedicated to your instrument. Here is what you need to know.

Wattage

The number of watts you buy for your amplifier is going to be determined by what you want to do with it. If you’re just playing at home, you probably don’t even need an amp your instrument will be loud enough for you to hear it. If you’re going to be playing in a gig situation such as a club, then you’re going to need an amp. You will need enough wattage so that it can be heard throughout the venue. If you play in large venues, you’re going to need more wattage. If you play with a loud drummer, you will want to increase the wattage of the amp so that the keyboard can be heard over the loud drum set. In some venues, your keyboard will be put through the system as well to increase the overall volume.EQ, Channels, and other features. PA systems will have more wattage as they need to cover more instruments.

Channels

You will probably want to get an amplifier that has more than one channel. This will allow you to connect other instruments, keyboards, microphones, or other output devices such as a drum machine or a computer. You will find quite a few 2-channel amplifiers as well as 4-channel models among the higher-powered products on the market. Your keyboard amplifier will probably have some mixing features churches adjustments for each channel, and you may also have EQ controls to cut or boost some of the frequencies. You may also find them with effects such as chorus or reverb. There may also be settings for effects, which can help you change the tone.

Inputs and Outputs

Have a look at the other gear you are using now. You’re going to want an amplifier that is compatible with that gear. This means you’re going to have to have the required inputs and outputs on the amp you buy so you can use your other gear. Not all amplifiers will have the input and outputs that you are looking for. You will have to analyze the various models to ensure you get one that is going to be compatible with the gear that you are currently using. Newer amps have USB ports and Bluetooth functionality so they work with today’s technology.

Portability

Another thing you have to keep in mind is how portable the amp is going to be. You don’t want one that is too heavy if you were taking it back and forth to a gig all the time. You can also get ones that have both speaker cabinets and amp combinations that are easier to carry around. Try to buy equipment that is going to match the gigs that you are playing. If you buy something that is too large, then it’s going to be overkill. You may want to have several amplifiers at your disposal if you play different sized gigs all of the time.

Amp Types

There are several amp types that you may want to look at prior to buying your keyboard amplifier. Here are the main types.

Combo Amp

A combo amp is probably your best bet. These come in a wide variety of wattages and they are easy to take with you to a gig. They tend to have effects and a wide range of inputs and outputs for things like microphones, headphones, or other audio equipment. A low wattage combo is fine for practice, but if you plan to play on stage, add some more watts. You will probably want 40 watts and above for the stage especially if you play with a loud drummer.

Stack Amplifier

Unless you’re going to play a large arena, you won’t need a stack amplifier. These are typical offer 100 watts and come with several cabinets as well as an amp head. If you play in a professional band in large arenas, then these amps are common, but not so much for clubs and other closed-in places. In this case, a good combo amp would probably be better for you.

Practice Amp

Technology has come a long way when it comes to practice amplifiers. There is a wide range of different models on the market. These amps are usually quite small and portable so you can take them with you to your lessons. They typically have around 5-15 watts of power which is perfect for practice sessions. These products often come with headphones jacks for quiet practice as well as built-in effects. Some allow you to use other instruments as well as our keyboard.

Can I Use a PA System?

A public address system or PA system is often used on stage with instruments such as a keyboard. On professional stages, you will find these units. One advantage when you use a keyboard amplifier dedicated to your instrument is that it is portable and there is less setup, but the sound will suffer if you don’t use the right equipment which the PA provides.

They often come with plugins for your microphone and other instruments so you can sing and play at the same time. When you use an amp, you have a bit better control over your tone and volume, and you will have consistent sound out of your keyboard no matter where you are playing. You will get to know the sound of your amplifier. You won’t have to rely on PA systems that might not work the way you expect them to. Another thing to keep in mind is that these systems can be quite expensive. If you’re just starting out, an amplifier might be the better solution as it’s going to cost you less.

As you get better at keyboards this type of system can be a solid option for the stage as they have a lot of mixing features that you can cause to shape your sound. You can also plug in other instruments to the system. You should experiment with both a PA system amplifier and a regular keyboard amplifier to find out what works the best for your needs. You will need other equipment such as monitors to use a PA effectively on stage.

Caring for Your Keyboard Amp

Get a Cover

You should have a cover for your amp. You don’t want to get dust inside the delicate electronics which is easy to do if you leave the amp out. Make sure it’s not around dusty areas such as a shop or other areas where there is a lot of dust. Keep it away from open windows as well. Your product will last a long time if you keep it covered when you’re not using it.

Hardshell Travel Case

If you travel a long way to gigs get a proper case for the amp. You can buy hard shell cases for the transportation of your amplifier. It can be worth it as you don’t want the delicate components banged around when you’re traveling long distances. You’ll find a wide assortment of carrying cases for amps to keep them safe during travels.

Keep Drinks Off of It

It can be tempting to place drinks on our amps while performing, but this can cause a spill and ruin your expensive equipment. Keep drinks and food off the amplifiers and use a small table or stand for the drinks. It only takes sone small error to send drinks flying and for that liquid to ruin your equipment.

Ventilation

Make sure the area is well ventilated and that the openings in your amp aren’t obstructed. This will prevent the unit from overheating and possibly burning pout if it gets too hot. Airflow around your musical equipment is critical to extending its life.

Periodic Maintenance

Make sure you take your amp in for periodic maintenance to extend its life. If you notice a problem with your amp or it doesn’t sound right get it checked to ensure that there isn’t a larger issue. Don’t try to do the repair yourself, leave it to a qualified technician. You may void the warranty if you try to repair it on your own.

Watch the Volume Level

Make sure you turn the unit on with the volume at zero, you may damage the speakers if you switch the system on and everything is up to 10. Turn the volume up gradually until you get a level that is comfortable for your needs. More power is sometimes not needed.
