I'm using TJ10 po na karaoke player. Maganda po sana kaya lang, lakas po mag feedback. Any solution po para mawala ito except feedback destroyer po (wala pa pong budget para doon hehe.)

Other than getting a real super-cardioid MIC like my noise cancelling TC-Helicon MP-75 eh I can only suggest keeping the treble at a lower setting and the system speakers nyo not pointing directly at you when you are in front of the audio system nyo riyan while singing.
