A Keyboard amplifier is basically a small PA disguised as a combo amp. Modern electronic keyboards are probably the most demanding instruments on the planet. They produce a full range of sounds that are very demanding when it comes to amplifier components. Keyboard amps are required to recreate many different types of sounds with clarity and accuracy. To fully appreciate the quality of the sounds in your keyboard, it's critical that you're amplification system is up to the task.
Solid-state technology is perfect for such a challenge. Solid-state combos, (Short for combination) are amplifiers that combine the speakers and the amplifier in one box.
Many keyboard amps have multiple input channels built into them to accommodate a number of keyboards at one time.
It is not uncommon for the channels on this type of amp to have little or no EQ (equalization) to adjust tone. The sounds produced by today?s keyboards are very smooth, well-balanced tones that often sound best without any additional equalization.
Keyboard combos usually incorporate a high-frequency driver, also known as a tweeter, to deliver the crisp high-end frequencies that aren't quite as present with a cone speaker. Many keyboard amps often have multiple sizes of speakers (similar to PA enclosures) to deliver a full-range of crystal clear sound. Many larger Keyboard amps can be used as a small PA, with low-impedance inputs for vocal mics. These are often fine for small coffee house or Bookstore gigs, but when the venue is bigger and noisier, it would be best to go with a traditional PA system and use the amp as a stage monitor. Keyboard amps will often feature a low-impedance Line out which allows you to send the amps mixed signals directly into a PA system.
