A Karaoke Machine That Connects to Your TV

The TV is only the lyrics screen: the machine makes the sound and the TV shows the words (through YouTube, a karaoke app, or an $8 HDMI cable), and what you should never do is sing through the TV's own speakers or your soundbar.

If you buy through my links the site earns a little. It's never why I pick things.

The TV is just the lyrics screen. The machine makes the sound, the TV shows the words, usually through YouTube or a karaoke app running on the TV itself. Some machines connect with an HDMI cable, about $8. The one thing you should not do is sing through the TV's own speakers or your soundbar.

how to connect a karaoke machine to your tv: words on the tv, sound from the machine

Split the job in two

At the karaoke place, the words are on a screen and the sound is loud. Those are two separate machines doing two separate jobs, and once you see that, your living room gets easy.

Sound comes from the karaoke machine. Words come from the TV.

They don’t even have to talk to each other. That surprises people, and it’s the cheapest good news on this page.

The setup most people should use, tonight, for free

If you have a smart TV, you already have a lyrics screen. Open YouTube on it and search any song with the word karaoke after it. The words come up.

Now turn the TV’s volume all the way down. Sing into your machine, or your mic, and let the machine be the sound.

Two devices, no cable, nothing bought.

Yes, that means the backing music comes out of the TV and your voice comes out of the machine, from two different places in the room. It's not perfect and it's completely fine. Nobody at your party will notice, and you spent nothing.

The HDMI way

Some machines have an HDMI socket on the back. Run an $8 cable from the machine to the TV, switch the TV to that input, and the machine puts the words up on the big screen itself.

That’s the setup people picture when they type “karaoke machine hdmi.” It’s tidy, it’s one device, and it means the songs come from the machine’s own library, which brings its own problem.

Machines that carry a big built-in song library often turn that library into a subscription. I go through that trap here. Most families are happier with YouTube and no library at all.

Never through the soundbar

This is the part I’d put in bold on the box.

Do not run karaoke sound through your TV speakers or your home theater soundbar. The karaoke people who do this every week say it plainly, and so will I: it sounds bad and it can genuinely damage speakers that cost more than everything else in the room.

A soundbar is built for movies and music, which are polite, mastered signals that never exceed a known ceiling. A microphone with a person shouting into it is neither polite nor bounded, and karaoke adds echo, which stacks the loud parts on top of each other. Home A/V amplifiers protect themselves by clipping, and clipped signal is what cooks tweeters. The little speaker in your soundbar's tweeter is a delicate thing designed for cymbals, not for a nine-year-old screaming "Let It Go" with the echo knob at maximum.

Sing through a karaoke machine, or a powered speaker, or a party box. Those things expect to be shouted at.

Machines with their own screen

There’s a third path: skip the TV.

Some machines have a screen built into the machine, so the words live where the sound lives and nobody has to configure anything. That’s what the Ikarao-class boxes do, starting around $200. The portable machines page covers them.

"Karaoke machine with screen" is an ambiguous phrase and people get burned by it. Sometimes it means the machine has a screen. Sometimes it means the machine needs your screen. Read the box twice. And don't pair a karaoke mic to your TV over Bluetooth: your voice arrives late, and you cannot sing on top of yourself.

Got a smart TV and any machine at all: put the lyrics on YouTube, run the sound through the machine, and you're singing tonight for free. Buying new anyway: get the machine with its own screen and stop caring where the TV is.

If you're figuring this out, you're probably also wondering:
