Do You Need a Karaoke Amplifier?
A karaoke amplifier is just like all other amplifiers, but it designed especially for 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 are all features that any 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 feature in particular is multiple inputs, which enables you to get audio signals from more than one source. If you have an iPod and a karaoke machine, you no longer need a mixer because you can use your amplifier. Most also have 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 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.
You must match your amplifier to your speakers. Ensure the main speakers are able to handle more power than the amplifier, but it doesn't need to be too much more. For example, if you have an amplifier that can put out 300 watts, a speaker that can handle 450 watts is 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
Be careful when buying a subwoofer because most come in at 1,500 watts and you don't want to run it off a simple 300 watt amplifier. By doing so, you could burn out the amplifier and not get good sound quality because it needs more power than it is currently getting.
