Problem with Rotel RB985 Amp.

[N2siast]

Hopefully someone can help me out. I noticed today when I turned amp on the center red light stay lit for about 1 minute. I then noticed that my center speaker(HTM 62) woofers are pulsating even when no sound is being fed the speaker. I do get sound emitting from the speaker; however I'm concerned about this pulsation going on with the speaker.

I hooked this speaker to the receiver in my bedroom and it did not exhibit this pulsating movement. Can anyone shed some light as to what the problem may be.

Thanks :cry:

I would see if another speaker does the same thing on the center channel output. And then I would swap the center and right RCA cables to see if the problem stays with the center amp. Try to narrow it down to the amp.

I tried that using another speaker and also tried another rca cable and problem still exists Is it possible the fuse may be out?
