I have a set of older stereo speakers hooked up to an older amplifier (1990's) and am experiencing a low humming noise coming from the speakers when i turn the volume all the way down on the amplifier. I have the auxiliary rca cables connected to my TV. When the tv is turned off the humming still happens. Its not that noticeable but it annoys me that its there. Any suggestions on how to fix this? Is it because i'm using old equipment(quality of speakers are still good)? The wires are just hanging behind my tv stand maybe its making an interference being so close to all the other wires. Help would be appreciated! Thanks.
Also, my right speaker goes out when I put on Low Cut. Any help on this also?
edit: I also read that a Ground Loop Isolator may help?
