I have a new set of karaoke microphones that I need to connect to my speakers. I have heard that I would either need a pre-amp or a mixer to connect the microphone to my speakers. I'm not quite sure which one I should get. I know that the mixer mixes my microphone's audio with my TV's audio output, which then can be outputted through my speakers. And that a pre-amp just amplifies the audio signal. Which one should I be getting? And does the quality of the product matter?
There are some $30 mixers on amazon, but I have no idea if they are good enough for karaoke.
