Hi
I'm wondering if anyone can enlighten me: I've got a Rotel RA-11 connected via two optical toslink cables to a PC and a Mac which I use as audio sources. I've not had any problem with the quality of the output from the amp but as a test, I just ran a frequency generator on both the PC and the Mac to push a single frequency sine wave tone through the amp.
When testing using both optical input sources (with speakers and then repeated with headphones) I could hear a clicking sound as I rotated the volume control on the amp as though there was digital interference between the component circuitry and the signal on the optical input.
I can't hear this when playing music so I'm not going to lose sleep over it, but just interested to know if this happens with other amplifiers and whether it is a sign of something failing with the amp circuitry.
Thanks for reading and any insight you can provide
