Most problems are menu settings, because surround modes can be complex and confusing. Verify what surround input type you are using. FM tuner will not play center spkr unless put into a simulate or expand stereo mode. Do other surround speakers work other than normal L/R stereo mode? You can try redoing your auto surround setup (MCACC) or going to the manual speaker setup and verifying speaker is turned on in menu system. Rechech you listening mode setups at Pages 33,38,39 in your manual. Try another speaker and wiring on center output. Try Different surround inputs, some manufactuers have had problems with their DTS and HDMI boards. Otherwise take to repair.
Assuming that you mean Dolby digital 5.1, confirm that you have a center channel properly connected and perform the following;
Using the remote, enter the menu on the receiver and navigate to the selection labeled "LEVEL." Toggle through the selections until you reach the "CENTER CHANNEL". You will be able to use the remote to increase the volume of that channel in .5dB increments.
There are a few things required for the rear surround channels to operate;
1. The surround back channels must be enabled in the surround setup menu.
2. The media being played through the receiver must have audio encoded for the rear surround channels. There are only a few exceptions to this but I'll exclude the explanation for simplicity.
3. The audio level of the speaker channels must be set high enough to be audible.
Enter the surround setup menu with your remote. Use the center button on the remote to toggle through the selections, press down on it to enter the selection. You will navigate to a selection in the surround setup menu that says "surround back" or S/B with a selectable yes or no indication. Press on the center button to enable them.
Media like DVD or Blu-ray that has 6.1 or 7.1 channel audio has separate, or often referred to as "discrete" or "matrixed" audio intended for playback through surround rear speakers, depending on the music or movie. If your media is encoded for 5.1, then there will be no audio sent to these speakers. However, with the different modes of on-board digital processing of this receiver you can still have audio through these speakers.
Last but not least is the actual playing level of these rear surround channels. They may simply be adjusted to quietly. Enter the setup menu with remote, choose "level" and navigate to the rear surround channels. You can adjust the level up or down in 1/2 dB level increments by toggling left or right with the center button. Each surround channel can and should be adjusted independently and equally.
Hello Shantilla hi, the orange port is for the Center speaker for a 5.1 surround set up. to enable this you need to find the controls of the sound setup. usually on the lower right side of the computer. If the sound card is a Realtek brand the sound manager is the orange speaker ICON, need to open this sound manager software and enable 5.1 surround. You need the SOUND driver to use the surround setup.
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
Perhaps you have the live wire in the wrong connector from the speakers? They should be color coded. I would check that first. And if you have moved, they are most likely in different positions, you'll have to rerun the audio setup for the surround sound. You should have a separate microphone to use for that that plugs in to the system.
The surround processing portion of the unit has a problem. In either stereo or direct mode, the digital procesing is bypassed. This could be just the surround processing IC, but that IC may not be available as a separate part. I would suggest that you bring this unit to an authorized Onkyo service center for an estimate.
unit needs repair. Look at the b speakers. Conect a speaker or two to the B position. If you have no sound than your surrond sound is ok and the unit is bad. Sound comes directly into the b speaker and not threw the surrond system. My 6070 has a cold start up problem. no sound. time to purchase a new one. to costly to repair.
