Karaoke machines without built-in speakers usually have songs included and you can load them via USB, CD+G discs and cartridges. They are specifically designed to be connected to a home theater or any external speaker system.

Setting up a karaoke system with a home theater

So many people contemplate having a karaoke party because they have the ultimate home theater system but they end up not doing it because they cannot setup a karaoke system with a home theater. The setup is such a breeze and only takes a few minutes.

Connecting a karaoke system to a home theater

Here is a step by step guide on how to connect a karaoke system with a home theater:

Step 1

Find the audio output plugs on your karaoke system. They are usually red and white in colors. Since on most models the audio outputs are placed side by side with audio input plugs, be careful to plug in correctly as labeled.

Step 2

Use your RCA cable to connect the plug labeled ‘out’ on the karaoke machine to the Home Theater’s RCA labeled ‘in’. The labels might differ across different models. Some home theaters have their RCA plugs labeled AUX 1, AUX2 and so forth. Be careful to make the correct connection.

Step 3

After successfully connecting your karaoke machine to your home theater, turn them both ON. Change your home theater’s input source to the grouping level that you had already chosen. If your system doesn’t have a grouping, you can search through all the options available until you hear the music that you want playing.

Step 4

The next thing to do is make volume adjustments. Adjust the volume of the microphone on both the karaoke machine and home theater. For you to enjoy the music audio, adjust the volume of the music then change the pre-defined settings on your home theater to either music or stereo.

If you experience any challenges when setting up the home theater, you can refer to the manufacturer’s instructions on the user manual. This will help you make proper connections without any mistakes.

In this setup, your karaoke machine acts as your music player and mic receiver. The home theater acts as an external speaker.

Remote control

You can use your home theater’s remote control to make volume adjustments. Some karaoke machines also come with remote controls for added convenience.

Voice control

It takes a lot to find the perfect balance of sounds. A good mixer can come in handy at helping you achieve a perfect sound balance. You will be able to find the ultimate balance between voice volume and that of background music. If either of them is too loud, your overall sound will suffer.

A mixer combines several input sources like the music and microphones then sends them as a package to the speaker.

There are different kinds of karaoke mixers. Some mixer models feature built-in dials and controls that allow you to have independent volume levels. Some will even allow you to tune for echo, balance and tone.

Any decent karaoke mixer should be able to work with any karaoke machine, receiver or amplifier. If you are a casual karaoke fan, then you can get a karaoke machine that comes with a built-in mixer. On the other hand, if you have picky ears and you love to get everything just right then it’s best if you got a serious mixer.

Useful tips for a karaoke party
