    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.

Our denon 1708 only play on stereo mode,no sound when it select on 7 channel.. crackling on dolby. what is the problem on that receiver? please help

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.

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?

Can't get center speaker to work and I don't have a remote: We just had front L and R speakers set up and just bought a center speaker. No sound comes out and it's set up correctly. DTV setting. I no...

center speaker wiil not work all the time unless receiver is set to Dolby 5:1, any of your concert, live, hall, etc. will not work the center. Id start with that.

I cannot get my new center speaker to work???

Hi on a Denon receiver you generally have to do two things. By entering the on-screen setup go to speaker setup and select the center speaker and surround speakers if you have them. Depending on the age of the receiver it will ask you to select between yes or no (on or off) or none, small or large.

(most centers are considered small unless they have 5" or larger mid-bass drivers)

Next you will have to select a mode that activates the surround sound mode usually Dolby but many have alternates such as Neo, theater etc..

This should activate the center channel, you will need to then adjust it using the "Tone generator" or the Audessy setup program.

The goal is to have the same amount of sound coming from your front three speakers.
Hope that helps

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.
