What to do if I cannot connect to preset or favorite radio stations on my Denon AVR-E400 Receiver?
The radio station may not be currently broadcasting. Wait a while before trying again. The radio station may no longer be in service.
What to do if my Denon Receiver is not producing sound from the subwoofer?
First, check the subwoofer connections and ensure the subwoofer's power is on. Next, navigate to the menu and set “Speaker Config.” – “Subwoofer” to “Yes”. Also, if “Front” and “Center” for “Speaker Config.” are set to “Large”, and “Subwoofer Mode” is set to “LFE”, no sound may be output from the subwoofers, depending on the input signal or selected sound mode.
What to do if my Denon Receiver remote control is not working?
Try these steps: 1. Replace the batteries with new ones. 2. Ensure you are within 23 ft/7 m of the unit and at an angle of within 30°. 3. Remove any obstacles between the unit and the remote. 4. Verify the batteries are inserted correctly, checking the q and w marks. 5. Move the unit if the remote control sensor is exposed to strong light. 6. Press MAIN or ZONE2 to select the correct zone to operate.
Why does my Denon AVR-E400 Receiver automatically switch to standby mode?
The sleep timer may be set. Turn the power on again or change the sleep timer settings. Also, “Auto Standby” is triggered when there is no operation for a set amount of time. To disable “Auto Standby”, set “Auto Standby” on the menu to “Off.”
What does it mean if the power indicator is blinking red in intervals of approximately 2 seconds on my Denon AVR-E400, and what should I do?
The protection circuit is activated due to a temperature rise within the unit. Turn off the power, and re-apply it after the temperature has sufficiently fallen. Re-install the unit in a place with good ventilation.
What to do if files on a USB memory device cannot be played on Denon AVR-E400?
Ensure the USB memory device format is set to FAT16 or FAT32. If the USB memory device is divided into multiple partitions, only files in partition one can be played. Ensure files are stored in a compatible format and are not copyright protected.
What to do if the AirPlay icon is not displayed in iTunes or on the iPhone/iPod touch/ iPad with my Denon AVR-E400?
Ensure that the unit and the computer or iPhone/iPod touch/iPad are connected to the same network (LAN). Also, verify that iTunes or the iPhone/iPod touch/iPad have firmware that supports AirPlay installed and update to the latest firmware if needed.
What to do if Internet Radio cannot be played on Denon AVR-E400 Receiver?
Check the Ethernet cable connection and ensure the network is connected. Confirm the program is broadcast in a compatible format (MP3 or WMA). Check the firewall settings of the PC or router. Ensure the radio station is currently broadcasting. Verify the set’s IP address. Some radio stations may go silent at certain times of the day; try again later or switch to another station.
What to do if no video is output with HDMI connection on my Denon AVR-E400?
Check the HDMI connector connections. Ensure the input source matches the connected HDMI connector. Verify the TV is compatible with copyright protection (HDCP); if not, video may not output correctly.
What to do if my Denon AVR-E400 Receiver is not producing sound from surround back speakers?
Check if “Assign Mode” is set appropriately to output audio from the surround back speakers. Set “Speaker Config.” – “Surr. Back” on the menu to something other than “None”. Also, ensure the sound mode is not set to “STEREO” or “VIRTUAL.”
