Low volume out of front and surround left channels (1 Viewer)

Hello,


I am having an issue with the volume levels from my two left channels in a 5.1 set up. I have an HK AVR 254 which is a preamp to a Carver AV 505. I have owned the 254 for about 5 years and have never had to adjust my speaker settings since I first set them up. Last night I found the volume levels were off (really low on the left only) and I could not get them loud enough to be equal to the other speakers in the system. I also checked the output knobs on the back of the Carver and found that they were wide open for all channels.


I have not updated the firmware on the 254 since I originally purchased the receiver as all that I use it for is for watching movies in a dedicated theater room.


Does anyone have any ideas about how to go about troubleshooting this issue? At this point I am not sure if it is related to the preamp or the amp itself.


Thanks,

Richard

Swap leads from HK left to right. If low volume moved...

HK.

If audio volume stays...

Carver.

Thanks, I will try that and report back. If it turns out to be the receiver, is this some thing that a firmware update could solve?

The usual suggestion is to un-plug the receiver for 30 minutes. If that doesn't do the trick then do a factory reset which is explained in the manual. Un-fortunately a factory reset clears all settings.
