A karaoke amplifier is just like all other amplifiers, but it designed especially for karaoke and karaoke machines. You will find those designed for home use and those designed for DJs. An amplifier for a karaoke machine makes it easy to setup and take down a karaoke setup and you get more features than a traditional PA system.These features typically include features that any DJ would appreciate. For example, many of the karaoke amplifiers are considered hybrid amplifiers because they have features normally associated with pre-amps.One feature is the ability to send audio signals from more than once source; this is due to the multiple inputs. If you have two audio sources, like an MP3 Player and a karaoke machine, there is no longer a needed for a mixer. Most also come with a radio tuner.A typical karaoke amplifier has enough power to run four or more speakers efficiently. For a good karaoke setup, you will need 2 main speakers, at least one subwoofer and at least one monitor speaker. The main speaker and subwoofer work together to get all of the sound out to the audience.The monitor speaker enables the karaoke singer to hear themselves. The best applications, like amplifiers, for DJs have a built-in crossover; this means the subwoofer's low frequencies only go to the subwoofer and this keeps them separate from the rest of the mix. Since higher frequencies don't need as much power, you can run the monitor and main speakers on the same channel.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.If the amplifier is able to put out eight hundred watts, then an individual speaker must be able to handle one-thousand. However, when running that many watts, you will likely be running multiple speakers. In this case, you add the wattage of each together to determine how much they can handle. With eight hundred watts, you could run two five hundred watt (or even four hundred and fifty) speakers, or four two to three hundred watt speakers.Keep these figures in mind when buying a subwoofer because you don't want to run a 1,500 watt subwoofer on a 300 watt amplifier. If you do, you won't get the best sound quality and may even burn out the amplifier because more power is needed than what is being provided.
