Denon AVC 3020: Dolby setting starts to crackle then front speakers disappear and center speaker quality is reduced. This happens after about 5 minutes of watching any Dolby source playback.

    Im having the same problem. It is intermittent and seems to go away if i jog the reciever back and forth or bounce it lightly. I know its old but its still a great piece. If you figure it out let me know.



    Thanks

Rear speakers only work during calibration and testing. Not during playback.


This commonly happens based on the source. For example, if your receiver looks at the source that is analog, it will use two channels, the two front left and right speakers. However, some receivers, such as a Denon, have a 5 channel stereo feature that will utilize all 5 speakers (L&R Front, Center, L&R Rear). If you are connecting a DVD player, often you need to configure the source appropriately. If you are connecting using the RCA cables, it will be stereo. If you are using Optical or Coaxial connection, you can enjoy Dolby Digital, but may need to specify in the receivers setup to use these audio source inputs. If you are connecting via HDMI, early versions only supported Dolby Prologic, but you occasionally hear mono sound from rear speakers. Without knowing more about your equipment, what source you are hoping to hear and how you are connected, it will be difficult to pinpoint your cause, but hopefully this helps your understanding to enable you look for the appropriate cause.

The surround sound outputs outputs ic's in the remainder of the system have opened, or there is a short in the speaker wiring, check to make sure that is not the case, if okay! you will need a repairman to assess the situation.

I was given a Denon AVC 3020 amp that was connected to a Denon AVR 1082 receiving. The receiver is working fine but I can't seem to reconnect the amp back nor can I use the amp independently from the...


So you want to slave the 3020 to the 1082, right? Use the Pre-outs on the AVR to feed the amp. I imagine the AVR manual, which I cannot find, talks about that.

Denon avc-3020 amplifier, both rear speakers play the same sound, sounds from the left also play through the right rear speaker and vice versa


You really need to read the manual and maybe physically rearrange your speakers for that left / right swap thing. Back Surrounds (if that's what you meant) frequently are the same unless the origianl program material has 7.1 sound.

How did the Test Tones fare?

Speaker crackle


HDMI is a High Definition Multimedia Interface and has the capability to transmit both AUDIO and VIDEO all in one cable. Your setup right now is transmitting 2 audio frequecys (L/R stereo RCA and HDMI) into the Denon inputs. Not necessary! I would recommend eliminating the red/white audio cable from the direct tv box to the Denon.

After doing such, your receiver should be able to process audio/video signals appropriately. REMEMBER to unplug all POWER CORDS before reconnecting any speaker/audio/video cable, as it may cause a small electrical surge and fry a micro component in your system!

Speaker interference


you should be able to disconnect the analog audio cables from the cable box and Denon, with the HDMI connected, press the input mode button on the front left of the reciever to select auto and that should fix the issue

Denon reciever avr-487


If your tv is putting out mono you will only get the center and sub speakers. This can be because the tv is only mono, or the output is set to mono in a menu of the tv. If you have cable or sat run the digital audio out to you receiver; it usually sound better that way anyhow. Set your receiver to Dolby mode for best sound.
