Please note that most of Karaoke Player’s HDMI in the market are the same.  The purpose of HDMI is providing better video quality, and sound because it is made for home theater, unfortunately it is not specified for singing. Therefore, we suggest customer to use AV (white/ red cable) in order for microphone successfully transfer your voice into the system. Thank You.

*We suggest customers to sing songs with a pair of speakers instead of directly connecting to TV because it may damage the TV’s speakers. For the best sound feedback, we suggest customers to get an mixing amplifier and speakers. If you have any question about speakers or amplifiers, please feel free to contact us.
