A karaoke amplifier is a powered amplifier designed specifically for the needs of the avid karaoke equipment owner. Many are designed for the karaoke DJ while a few are more designed for home use. They typically are designed to make hooking up and taking down a karaoke rig easy and provide numerous extra features over a typical public address system power amplifier.
These are all features that any karaoke DJ would love. In fact, some karaoke amplifiers are known as hybrids because they have some of the features normally found on pre-amps.
One of these features is multiple inputs so you can send audio signals from multiple sources. This eliminates the need for a mixer if you have two audio sources, such as the karaoke source and an iPod for filler music. Many of these units also include a radio tuner.
A standard karaoke amplifier should have enough power to efficiently run four speakers. For a good setup, you want one speaker for the monitor, one speaker for the subwoofer, and two main speakers. The main speakers and the subwoofer are what gets the sound to everyone in your audience.
The karaoke singer can hear themselves through the monitor speaker. The best karaoke amplifiers have a built-in crossover, which means that the low frequencies from the subwoofer will only go through that subwoofer; this helps to keep them separate from the mix. For the best results, run the main speakers and the monitor on the same channel because the higher frequencies do not need too much power.
Be sure to match your amplifier to your speakers and vice versa. You want to make sure the speakers can handle more power than the amplifier can put out, but not by too much. For instance, if your amplifier can put out three hundred watts, then speakers that are rated to handle four hundred and fifty watts would be perfect.
On the other hand, if you have an amplifier that can put out 800 watts, the speakers should be able to handle 1,000 watts. On that same note, you need multiple speakers when running that many watts. In this event, you can add the wattage of each speaker and combine them together to determine how much they can handle as a pair. For example, an 800 watt amplifier can have two 450 watt speakers or another similar combination like four 200 watt speakers
The flip side of this is buying a subwoofer that is rated for fifteen hundred watts and only running it off of a three hundred watt amplifier. You will likely burn out the amplifier and never get a good sound from the speaker because it needs more power than it is getting just to properly produce sound.
