Is it possible you have the gain cranked up on the center channel and needs to be adjusted? A line conditioner will not solve that problem if the issue is only the center channel. Is this the first time you've noticed this, or is this a new issue? How long have you owned the system? Any new cables, or any changes made to the system recently?
Low level noise from spkr when nothing is playing
I need your help finding out why I am getting low level noise from my center speaker, even when nothing is playing. When I put my ear up to my center speaker I can hear low level noise. My system is made up of the following components: Sherborn 7/125A 7 channel power amplifier, Krell HTS 5.1 Control Amplifier, Faroudja DVD/CD DV-1000 player, Front Martin Logan Source Speakers, Center Krell Resolution 4 speaker. These are connected with MAC Silver PB Speaker Cables and Ultrasilver XLR cables. What can I do to test where the problem is coming from? I do not have a line conditioner. Will that fix the problem?
