Question about Audio Players & Recorders

1 Answer

I have a Denon AVC 3030. In pro logic mode it makes a rumbling through my right and left speakers. During quiet parts of movies it is quite annoying. I know it's old but I really like it.

    It goes up with the volume. When there is no action it sounds like someone tapping morris code into a microphone. Or like someone standing in the wind with a microphone.

If what you mean is a low humming sound when the volume is turned down to minimum level, this is usually from power supply filtering problems. Most of the time this is from the electrolytic filter capacitors going out of spec with age and use, and or voltage retulation problems.

If the sound is quiet with the volume turned down, and the hum or buzz increases with the increase of the volume control, this is usualy due to a ground loop problem between the associated equipment connected to the amplifier, or a bad interconnect cable.

All the speaker outlets seem to work fine, except the fronts, all will work, but if i plug the fronts in, all the sound then tends to just fade away, and then i have nothing, no sound. i can't figure...


I would:
1- First make sure you are properly testing using a reliable source, such as a CD Player or itunes. 2- Make sure the Listening Preset is not on Dolby Pro Logic. Make sure it is on Stereo mode and see if the problem persists.
What usually happens is that when listening to 2ch (Left and Right) Audio such as Television or Music and Dolby Pro Logic is on as a preset, Dolby Pro Logic analyzes both Stereo tracks, tries to detect the voices (center channel), ambient sounds (surround and fronts) and processes the signals into a 5.1 or 6.1 System. You tend to get a fading effect when Dolby Pro Logic is selected and listening to an old VHS, DVD or even music.
To remove a preset, make sure you select the Stereo button at the bottom left of the remote to pan through the options.
Hope this helps

We hooked it up and have no sound


From the Console Settings screen in the System area of the Xbox Dashboard, you can configure the video output of your Xbox 360 console for a widescreen, high-definition TV, determine your audio options, and check your console's serial number and Xbox Dashboard version.
Go to correct section for ... Audio

Change your audio output settings for games from this screen. These audio settings do not affect DVD movie playback. For DVD audio settings, refer to an individual DVD movie's setup screen.

Settings consist of:

  • Analog Output Settings: choose Mono to merge the left and right audio signals so that you can hear all sound through a connection to a monaural TV or monitor; choose Dolby Pro Logic II to listen in normal stereo (no audio surround receiver required) or to listen to Dolby Pro Logic or Dolby Pro Logic II soundtracks from compatible games or other media.

    Dolby Pro Logic consists of four channels of audio: front left/center/right and a monaural surround channel that is mirrored in each of your rear left/right speakers. Dolby Pro Logic II uses digital signal processing to generate 5.0 audio (front left/center/right, rear left/right) from any stereo (left/right) programming, whether from movies, music, or games. Unlike movies and music, however, games are specially encoded with Dolby Pro Logic II decoding in mind.

    To listen in either Dolby Pro Logic or Dolby Pro Logic II surround sound, you must connect your cable's left/right (white/red) RCA connectors to a compatible surround receiver. For more information, see our connection page for the cable you're using:
  • Digital Output Settings: configure this setting only if you'll be using the Toslink optical digital-audio output from a compatible Xbox 360 AV cable (optical digital-audio cable sold separately):


    The default digital-audio setting is Dolby Digital 5.1. If this is your preference, you do not have to make a selection from this screen.

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?

The rear and centre speakers are not working but the front and subwoofer speakers are working. What do I need to do to get the three working. In the booklet it says the rear speakers might not work becasue...


From them manual Troubleshooting section:

"When listening to a CD or radio, sound is output to the front
speakers (L/R) only. Select "PRO LOGIC II" by pressing
PL II (Dolby Pro Logic II) on the remote control to use all
six speakers.
• Make sure that the DVD disc is 5.1-CH compatible.
• If you set C, SL, and SR to NONE in the speaker mode in the
audio setup of the setup screen, no sound is heard from the
center speaker and the rear left and right speakers. Set C,
SL, and SR to SMALL."

This means you might want to check your speaker settings again and make sure the Cenyer and Surrounds are defined.

Denon AVR 1910 Volume Level


My Pioneer VSX-36TX (circa 2002) does the same thing. Modern AVR's count up from minus something to 0db and go just a few db higher into 'plus' territory. It seems arbitrary but that's how it is.

Ask yourself this: who ever really turned the volume knob up to maximum on any amp on purpose, and had speakers survive it? In other words, why have all that capacity on a potentiometer if you never use it?

Little known fact: With that in mind, Bose Corp actually designed a product that intentionally used the full physical travel of a volume control - the Bose Acoustic Wave Music System.

Can't get clear sound when not in "bypass" mode on Denon Pro Logi


From the FM radio mode, from your remote press the speaker button to make sure just the front speakers are on, make sure surround is off and use the tone cotrol button on the right side of the amp to adjust the bass and treble. That should clear things up a bit
