If the MUTE/STANDBY LED on your Denon Amplifier doesn't light up and no sound is produced when you turn the power switch on, make sure the power supply cord is properly connected.
What to do if the Denon Amplifier remote control is not working?
If your Denon Amplifier isn't responding to the remote, start by replacing the batteries with new ones. If that doesn't work, make sure you're close enough to the unit and that there's nothing blocking the signal. Also, ensure you're pressing the correct button and that the batteries are inserted with the correct polarity.
What to do if my Denon PMA-2000IVR has no sound but the standby light is on?
If you're getting no sound from your Denon Amplifier but the MUTE/STANDBY LED is lit, check the following: ensure the speaker cords are securely connected, verify that the INPUT SELECTOR is set to the correct position, and make sure the VOLUME control isn't turned all the way down; adjust it to an audible level.
Why does my Denon PMA-2000IVR Amplifier only play sound on one side?
If you only get sound from one side with your Denon Amplifier, check that the speaker cords and input cords are securely connected. If the connections are good, adjust the BALANCE control to center the sound.
How to fix inverted stereo sound on Denon Amplifier?
If you notice instruments are inverted for stereo sources on your Denon Amplifier, check that the left and right speakers or input cords are not inverted. Correcting these connections should restore the proper stereo image.
What causes booming sound when playing records on my Denon Amplifier?
If you experience a booming sound when playing records on your Denon Amplifier, ensure the turntable's ground wire is securely connected. Also, check that the input cords are properly connected to the PHONO terminals. Finally, consider if there's interference from a nearby TV or VCR, and if so, change the turntable's position.
Why is there howling when playing records with the Denon PMA-2000IVR?
If you are experiencing howling when the volume is turned up while playing records on your Denon Amplifier, the turntable and speaker systems may be too close. Move the speaker systems as far away as possible. Additionally, if the floor is soft and vibrates easily, use cushions to absorb the vibrations transmitted from the floor to the speakers.
How to adjust volume levels between tuner and records on Denon PMA-2000IVR Amplifier?
If the volume level is different when listening to the tuner and records on your Denon Amplifier, the tuner or record output may be different. Adjust the tuner output to match the turntable’s output, if your tuner has an output control.
