What is a Howling Canceller in a home theater system?

    1. A howling canceller is a feature that suppresses/eliminates the sharp, annoying howling sound produced by a microphone while using it.
    2. This is common in public address systems, but it can also happen when singing karaoke through your home theatre system.
    3. The howling sound is caused by sound feedback entering your microphone from the speakers.
    4. While the immediate solution is to point the microphone away from the speakers, howling cancelation automatically prevents this.
    5. Once activated you will not have to change your position or that of the microphone, giving you a pleasant karaoke experience.
