  Curtis OconnorAug 19, 2025
  If your Marantz Amplifier isn't responding to the remote controller, the issue might be due to several reasons. Start by replacing the batteries in the remote controller with new ones. Ensure that you are within the remote controller's operable range. Remove any objects that might be blocking the path between the remote controller and the unit. Also, avoid exposing the remote sensor on the unit to strong light.

Why is there noise or no sound when playing records on my Marantz Amplifier?
- L
  Laura CrawfordAug 26, 2025
  If you're experiencing noise or no sound when playing records on your Marantz Amplifier, check the grounding connection from the record player to ensure it's properly connected to the PHONO GND terminal of the unit. Also, verify that the output jacks of the record player are correctly connected to the PHONO IN jacks. Ensure that devices like a TV aren't placed too close to the record player, as they may interfere with the sound. Finally, check that the PHONO MC button is correctly set for the type of cartridge you are using (set to MC if using an MC cartridge).

How to fix uneven volume in left and right speakers on Marantz PM-15S2 Amplifier?
- M
  Matthew GrayAug 28, 2025
  If the volume levels from the left and right speakers are different on your Marantz Amplifier, the left- and right-channel volume levels (LEVEL TRIM) might be set unevenly. To fix this, set the trim levels for both the left and right channels to zero. Check that sound is output from both channels. Then, readjust the left- and right-channel volume as needed.

What happens when the protection circuit activates due to overheating on my Marantz PM-15S2?

  Matthew ValdezAug 31, 2025
  If the protection circuit activates due to the main amplifier overheating on your Marantz Amplifier, 'PROTECT' will flash on the display, and the volume will decrease automatically. After about 8 seconds, the protection circuit will deactivate. You can then adjust the volume again.

Why does howling occur when I turn up the volume while playing records on my Marantz Amplifier?
- T
  Toni RowlandSep 2, 2025
  If you experience howling when increasing the sound volume during record playing with your Marantz Amplifier, it could be due to the record player and speakers being too close together. Place the speakers as far away from the record player as possible. Also, the record player might be placed on a surface prone to vibration. If your record player didn't come with an insulating pad, consider using one available on the market.

Why is the sound from my Marantz PM-15S2 Amplifier monaural?
- B
  Brittany CampbellSep 6, 2025
  If the sound output from your Marantz Amplifier is monaural, check the MODE switch on the rear panel. If it's set to “BI-AMP”, turn the unit off, set the MODE switch to “STEREO”, and then turn the unit back on.

Why are the left and right channels reversed on my Marantz PM-15S2 Amplifier?
- J
  Jennifer WhiteSep 9, 2025
  If the left and right channels are reversed on your Marantz Amplifier, the speaker cables or input cables might be connected incorrectly. Check the cable connections between the speakers and the unit, as well as the connections between the source equipment (CD player, etc.) and the unit, to ensure they are correct.

Why is there no sound coming from my Marantz PM-15S2 speakers?
- E
  Erika SpencerNov 15, 2025
  If you're not hearing sound from the speakers connected to your Marantz Amplifier, there are several possible causes. First, check the speaker and input cable connections to ensure they are complete and correct. Make sure the INPUT SELECTOR knob is set to the correct position for your connected source equipment (like a CD player). Also, verify that the speaker volume isn't set to the minimum and the SPEAKERS button is set to ON. If 'ATT' is displayed, muting might be activated; press the ATT button or increase the volume. If using P.DIRECT IN jacks, ensure the unit is in power amplifier direct mode by holding the P.DIRECT IN button for at least 3 seconds. Finally, if none of these work, the protection circuit may have been activated; turn the unit off, wait a minute, then turn it back on a...
