First, verify that the buzz/hum is indeed coming from the RCA connections. If so, and if your karaoke machine has an external common chassis connection the this should eliminate the buzz/hum being created by the ground loop. Good luck with it.

It is common for a laptop to cause hum in audio equipment. Try unplugging the power supply from your karaoke laptop and see if that eliminates the hum. If the hum goes away, one on these should eliminate the hum when the laptop is plugged in. I bought a few of these recently and they worked very well, as well as the more expensive 'hum busters.'

Yes. Had a terrible hum in my boat, and the Crutchfield advisor recommended this for me. I was skeptical, but man, did it do the trick!
[ John Mar 24, 2019 ]

This helped mine, it does slightly lower overall volume but compared to the hum it was a very acceptable trade off.
[ Mark Mar 24, 2019 ]
Q
This says it works in the range of 20hz-to 20khz...is this going to limit my input then output to my speakers which are rated to 40khz?

Hello, Andrew! My understanding is that 20k is the high end of human hearing, I think the only one who will hear any difference is a dog.....:o) ! This part works great, sounds great.

Yes, it will limit the frequency, but your not going to be able to hear the frequencies that will be filtered out, most people only hear in that 20hz to 20khz range anyway.
