  If the power indicator on your Denon Amplifier is lit but no sound is coming out, it could be due to several reasons: * The speaker cables might not be fully connected - connect them securely. * The incorrect device may be selected - ensure the correct input is selected. * The volume control might be set to minimum - set it to an appropriate level. * The input cable may not be fully connected - connect it securely.

Why is there howling produced when playing records on my Denon PMA-2020AE?

  If howling is produced along with the music when playing records on your Denon Amplifier, especially at high volumes, it could be because: * The player and speakers are too close together - install the player and speakers as far from each other as possible. * Vibrations from the speakers are being transmitted to the player through the floor - use cushions, etc., to absorb the speakers’ vibrations.
