I am new here and write from Italy.
I own a Rotel pre/pro (RSP-966) which I use, almost 99% of times, to listen to music through DVD player, Apple TV2 and Tuner.
Lately it's happening that sometimes digital inputs just don't work, I mean, I switch the preamp on, select video 2 as source (dvd) and press play but I get no audio from the speakers, despite I know that dvd is playing fine, since unplugging the coaxial cable from the dvd side the Rotel falls back to analog rca inputs and music plays just fine.
I also have a graphic equalizer which I use when I want to boost some frequencies a bit (because my speakers are a couple of active nearfield studio monitor and they sound quite flat when volume is low), that's plugged to the Rotel through the "tape 2 monitor" loop and its spectrum analyzer confirms that analog signal is coming in correctly.
I can't figure out exactly in which circumstances this problem with digital inputs happens, but usually switching the Rotel off completely and on again fixes it.
Sometimes I get no audio switching source to tuner and then back to dvd, or apple tv (toslink), some other it happens as soon as I switch the whole system on.
The display of the Rotel seems to show the active input correctly because "coaxial" lights up with dvd and "optical" with apple tv even if nothing is heard through the speakers.
I tried loading a dvd video disc and the Rotel even shows Dolby Digital and DTS on its display, so I guess it's not a problem with cabling or with locking onto the signal (I think that if it shows which kind of encoded signal it's receiving then it already locked onto it?!)
Is there anybody who can help me figuring out what's the cause and to this issue?
Any suggestion is more than welcome!
