    Why is there no sound output from the center speaker on my Marantz Receiver?
    • T
      Todd BennettAug 21, 2025
      If no sound is coming from the center speaker of your Marantz Receiver, first check the center speaker cable connection to ensure it is correctly connected. Also, if 'STEREO' is selected for Surround mode, no sound will be output from the center speaker, so set another Surround mode. Finally, verify that 'Center = NONE' has not been selected in SETUP mode and make the correct setting.

    Why can't I change the surround mode on my Marantz SR9200 Receiver?
    • J
      Jesse EllisSep 3, 2025
      If you cannot change the surround mode on your Marantz Receiver, it might be because headphones are connected to the jack. Disconnect the headphones, as the surround mode will be fixed to STEREO when headphones are connected.

    Why is noise heard during FM reception on my Marantz SR9200 Receiver?
    • S
      Sheila SchaeferAug 29, 2025
      If you're experiencing noise during FM reception with your Marantz Receiver, it could be due to weak radio waves from the broadcasting station. Try installing an FM outdoor antenna or using cable TV/FM to improve reception.

    What to do if my Marantz SR9200 Receiver has no sound and picture even when power is on?
    • B
      burkecourtneyAug 27, 2025
      If your Marantz Receiver has no sound and picture when powered on, the issue might be due to several reasons. First, check if mute is activated and deactivate it using the remote. Next, ensure the input cables are correctly connected as per the connection diagram. Also, verify that the master volume isn't turned all the way down and that the function selector is in the correct position.

    • A
      alicia63Aug 27, 2025
      If there is no output to the Sub Woofer Out on your Marantz Receiver, check if 'Sub-woofer = NONE' has been selected in SETUP mode. If so, select 'Sub-woofer = YES'.

    Why is there no sound output from the surround back speaker on my Marantz SR9200?
    • E
      elizabeth19Aug 25, 2025
      If there's no sound from the surround back speaker on your Marantz Receiver, ensure the speaker cable is correctly connected. If 'STEREO' is selected for Surround mode, no sound will be output from the surround speaker. Also, if 'Surr. Back = NONE' has been selected in SETUP mode, change the setting. The surround back channel is only active in THX surround EX mode, so set the receiver to THX Surround EX mode.
