What does D = option 4 on the AVR 2807 mean?

SOURCE: How do you reboot the Denon AVR-2807 to factory settings

To reboot, turn receiver off by the small on/off button, not the big standby button. While off press the night and pure direct button at the same time and keep holding them with your right hand while pressing the small on/off button with your left. You will see your receiver menu flash. When you see it flash let go of the night and pure direct button and the receiver will reset it self to the radio station 87.50. The receiver's microprocessor has now been set back to factory. Enjoy this info is straight from Denon's Tech support. I had to do this on mine

SOURCE: What to use for Audio-out on Denon AVR-2807?

Hi Karmor

Use the Tape Out(rec) connections on the Denon. If that model has a rec out selector, then be sure to select phono as well. All sweet and ready to rip them files!!

Finally the problem was with the HDMI cable. When I pushed it in on the TV set the problem disappeared. It seems the connections must be quite firm on the HDMI cables otherwise anything may interfere to the sound.

I had the same problem. Rebooting did the trick. Reboot the unit per the instructions provided by another user on the main page. Here they are:

SOURCE: Denon AVR-1403 receiver switched from digital to analogue.

There are three modes (Auto, DTM, and PCM) on the input mode switch, on the main unit, selected by repeatedly pressing the input mode switch.

However, if you have already depressed the Analog button in, on the main unit you have predetermined the mode as analog.

On the remote, the INPUT MODE switch combines toggles for 5 choices, [Auto, PCM, DTS, Analog,
Ext. input]


My guess is that either the input mode switch on the main unit and/or the remote are toggled to analog.
