How to Set Up Wireless Karaoke Mics

Charge the mics or fit fresh batteries, switch on the machine, then the mics, and pair them if your manual asks you to. Set the mic volume low and raise it while someone sings, and keep singers beside or behind the speaker to avoid feedback. Pairing steps differ by model, so follow the manual.

Know how your mics are powered

Here's what the makers list for the machines on this site:

Recharge when docked: Ikarao Shell S1.
Rechargeable: Singing Machine ISM9025.
2 AAA batteries per mic, not included: TONOR K6.
Batteries not included: Singing Machine ISM9011; check the manual for the type.
Not stated on the maker pages we used: TONOR K20 and TONOR K9; check the listing.

Pairing the mics with the machine

Switch on the machine first.
Switch on each mic.
If the manual describes a pairing step, follow it for each mic in turn.
Check each mic's indicator, if it has one.

Some wireless karaoke mics link to their own machine as soon as they're switched on, and others need a pairing step.

Setting mic and music volume

Turn the mic volume down and the music to a comfortable level.
Ask someone to sing and raise the mic volume until the voice sits just above the music.
Add echo or effects last, a little at a time.

Stopping feedback

Feedback is the squeal you hear when a mic picks up its own sound from the speaker:

Keep singers beside or behind the speaker, not in front of it.
Lower the mic volume first, then the echo.
Don't point a mic at the speaker.

Adding a wired mic

If your machine has an unused mic jack, a wired mic adds another singer. The Singing Machine SMM-205 has a 6.3 mm plug and an extra 3.5 mm adapter, per Singing Machine, which lists two wired-mic jacks on the ISM9025. Check your manual for the jack size before you buy.

When a mic won't connect

Check the mic is charged or has fresh batteries, and that it's switched on.
Move it close to the machine.
Check the machine is in the right mode.
Switch both off and on again, then repeat the manual's pairing steps.

FAQ

How do I connect a wireless microphone to a karaoke machine?

Charge the mic or fit fresh batteries, turn on the machine, then the mic. Some wireless karaoke mics link to their machine on their own and others need a pairing step, so follow the manual for your model.

Why does my karaoke mic squeal?

That's feedback: the mic picks up its own sound from the speaker. Keep singers beside or behind the speaker, and lower the mic volume first.

Can I use any wireless mic with my karaoke machine?

Usually not, because wireless mics are generally matched to their own receiver or machine. A wired mic works if the machine has an unused jack that fits its plug; check the manual.

Why won't my wireless karaoke mic connect?

Check that the mic is charged or has fresh batteries, that it's switched on and close to the machine, and that the machine is in the right mode. Then repeat the pairing steps in the manual.
