What to do if Denon Recording Equipment cannot perform playback or recognize a file?

  Christine WilkinsonAug 18, 2025
  If your Denon Recording Equipment isn't playing files or recognizing them, try these steps: * Copy the file to another SD card and try again, as the SD card itself may be the issue. * Confirm that the unit supports the format of the file you're trying to play. * Ensure the target folder is located directly under the root folder of the SD card, as the unit only recognizes folders in this location. * Make sure the number of folders does not exceed 32, as the unit can only recognize up to 32 folders.

Why is there no sound reproduced when playing back properly recorded music on Denon Recording Equipment?

  Nathan BentleySep 7, 2025
  If music was recorded properly but there's no sound during playback, ensure that the recording level (REC LEVEL) is not set to MUTE. Also, verify that the recording settings (such as input source) and all connections with external devices are correct. For example, make sure to set the audio input source for recording to "Unbalance" and connect an external device to the analog input (RCA) terminal. Otherwise, the unit will record the music in silent mode.
