I have a Marantz SR6010 AVR.
Some time ago I fiddled with the Internet Radio and switched to Online Music.
Suddenly there was a very loud persistent squeel in the speakers. I didn't touch anything but the remote.
Luckily the volume were turned way down or I'm sure my tweeters would have been smoked.
My sub amp wasn't turned on at the moment.
Now I experience a raised noise level in the subwoofer output. About 6-10 dB louder I estimate. It is easily heard in quiet passages in music and movies.
It's low frequency white noise indicating it's induced before EQ.
There's no problems in the mains.
There's no problems with cables or the external sub amp.
Any suggestions on what might have gone south here?
Cheers,
Nordskov
