Question about Audio Players & Recorders

2 Answers

I have a denon avr -2807. the audio on the non hd channels is fine on surround sound channels. when we switch channels to hd the display says nor offset -8DB. What does this mean and how can it be put back to normal? Is there a basic how to manual that shows you how to set up the AV receiver? I have the manual but it odes not really walk you through step by step.

    Thanks for the comment but I don't understand your answer. I can certianly increase the audio on an HD channel by turning the dial but the sound blows me away when you change back to a non-HD channel.


    Let's give this another try.


    Here's is the problem.




    I have owned a Denon AVR-2807
    receiver for nearly 4 years. About three months ago, we noticed a significant change.





    If you are watching an HD
    channel the audio is underpowered by a significant amount. When you switch to a
    non-HD channel the audio is booming. The audio is at least twice as high if not
    more on the analog channel compared to the HD channel.





    When we switch from the
    non-HD channel to HD the readout on the face of the receiver flashes Dial norm offset
    – 7 DB and sometimes Dial Norm offset – 4DB.
    Somehow we must have changed
    a receiver setting because this happens to every HD and non-HD channel. For 3 ½
    years the audio was fine; now there is something wrong.





    If you simply increase the
    audio volume by using the dial on



    the receiver and then change back to a non-HD
    channel, the sound blows you away and is distorted.



    I am looking for a solution
    to bring back normal audio levels to all HD and non-HD channels.



    Please tell me how I can
    physically do this using the panel on the receiver. I am not using the remote.
    Please tell me step-by-step instructions on how to fix this issue. There has to
    be a setting that needs to be tweaked.





    Another thought: If we
    returned the receiver to normal factory or default settings, wouldn’t the issue
    go away? How does one do that? Once again, step-by-step instructions would be
    helpful if this is a possible solution. I would prefer finding the real issue
    before going to factory settings.

Here is a site for a couple of manuals that may help you:

Read the following blog- they say they have their cable box set to -10 db, and might clue you in:

8dB OFFSET reading on the main panel display it is an automatic adjustment the 2807 makes when receiving a Dolby Digital feed.Adjust the DB settings bit high and low and check.With each detent of the AVR-2807’s volume control knob while it is turned slowly, the volume changes in discrete steps of ½ dB, for a gain or reduction of 12 dB per each full rotation. If you turn it faster, the effect is accelerated,On the remote control, if you press and immediately release the volume button, the volume changes by ½ dB. In order for that press-and-release technique to be possible, it is necessary for there to be a brief pause before the volume is changed rapidly when you hold the button down. As the magnitude of the desired change becomes shorter, the pause makes up an increasingly greater percentage of the total time that you have to hold the button down.The volume setting is numerically displayed on the front panel, but the reason that the knob itself is not marked is that the volume control is electronic and there is no fixed correlation between the position of the knob and the volume setting. The AVR-2807 can’t superimpose graphics over component video or HDMI video that is passed through. In the case of component video, when the setup menu is entered or when the on-screen display button is pressed, the video input is automatically switched to the S-video or composite video input from the same source in order to avoid a black screen behind the graphics. In the case of HDMI, the graphics appear over a black background unless you enable analog-to-HDMI conversion, in which case the analog video input remains the source until you go into the setup menu and deselect analog-to-HDMI conversion. Try adjusting the DB settings and see. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

No sound from Russound ss-4 after connecting to BACK surround speaker connections on the 2807.


Check the speaker setup configuration in the setup menu. Many times the surround back speaker terminals can be assigned to something else like zone 2. They may just be turned off.

Can't get the sound to work on my TV using the Denon AVR-2807


In the 2807 the HDMI out is a video out only. Audio is not processed through the HDMI output.
If you are using speakers it is best to adjust the playback modes to stereo if you are annoyed with surround sound modes.
Please comment if I helped.

Loss of sound on the Denon AVR 2807 a/v surround receiver when I turn on and off lights in my house


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.
