Title: Center channel, comes and goes.
Post by: zerocul on Jan 23, 2019 at 02:30 PM

Hi

Currently my set up is only 5.1 channel, run by a Yamaha A/V receiver. I'm having issues when watching a movie or series that is 5.1, losing my center channel. Earlier it happens (no center) but it immediately returns. But now its totally gone, center channel (no voice). My only fix is to switch the receiver to 5 channel, meaning every speaker is voice and background. Has anyone experience this before, what's wrong and how you fixed it? Thanks for the help.

Happened to my Denon. Culprit was a loose connection on the speaker cable.

You can temporarily use front left or right speaker as center speaker. If dialog is audible your center speaker is defective. Otherwise the center channel (processor, pre-amp or amp stage) itself is defective.

My center speaker and cable are working and no loose wires. As I mentioned, Yamaha A/V receivers has a function of "5 channels", were in all speakers are  ON (5.1). All are active, acting voice and background, not separated, when that is enabled center is working fine. So its not my loose wire or defective speaker.  I just want to find out if someone experienced this, if it is the receiver or the optical cable, that's malfunctioning?

Do you know what might cause this issue you mentioned about the (processor, pre-amp or amp stage)?

Ive had a denon once, but have not experienced this.

But my questions/ suggestions:

1. Have you tried to reset the amp? I'm sure there's a factory reset.
2. Is stereo mode working? Because you said that your only solution is to use the 5 channel. I'd rather use stereo than 5 times mono.
3. Have you changed source? Changed source input? Swapped DTS/Dolby or whatever else your amp uses for 5.1?
