View Full Version : Rotel RSX1056

By the way, I can repeat it every time---guess how? I switch an outside
light on/off... and my receiver loses the loc on the DAC signal. My SB2 and
receiver are plugged into a "brickwall" MOV or similar. The light switch is
maybe on the same circuit.

Is this thing safe?

Thanks,
Phillip

Safe, yes. I've already figured out the problem is just that the
waveform is not quite as sharp as the rotel wants it. This is really
simple to fix by changing the ferrite filter on the output, but there
is a tradeoff between slew rate and EMI output. Therefore before I can
offer a fix I have to have it tested and approved by our lab.

More details coming in a few days - you'll need to send your unit in if
you need the fix. Otherwise please use the optical or analog outputs as
a workaround.

On the basis that this is a bandwidth limiting problem - is there a case for trying a shorter piece of low capacitance cable first?
[Something designed for high bandwidth use rather than audio use - e.g. cable for video signals, or off the shelf cable designed for
spdif]

I've found quite a difference between cheap cables in terms on bandwidth when looked at on a scope for rounding of the signal - it
could be that the cable shiped with the Rotel is not too hot?
