Flashing Red db on line-in
#1
I tried the SuFu on this topic and found some info in the Vinyl thread but it really didn't answer my question.

What does one need to adjust when getting the flashing red db in the dev display with a standard rca line-in? (not phono)

Thx

Increase the max. input level in the configurator for the line inputs would be my first thought.

Thx, that was quick.

Believe it is currently set at the standard 2mV (?), what would be a good increment of change? Is there anyway of telling when/if it becomes to much of a good thing?

I believe that this can be changed on the fly with the remote. Either you will be using ridiculous amounts of gain to get the desired volume or, as in your case, the amp will be clipping. Try using the level meters to get your peaks as near as possible to 0dB.

You're overloading the Devialet inputs resulting in clipping. Thumb5 is right. You'll need to set the max input level (2Vrms by default) of the Devialet inputs to the maximum output voltage of the analog outputs of the device you're connecting to it. Most manufacturers specify this basic and important parameter in the manual or published specs elsewhere. If they don't contact them.

I would not recommend going anywhere near 0dB. I know most recordings these days are hammering up against the limiter, but they still won't be clipping if properly mastered. There is no limiter software in the Devialet, so -6dB peaks is a good target.
I have been recording music for 50 years now, and whilst with tape a high recording level was needed to keep away from noise (and a bit of tape saturation sounds euphonic) with a 24 bit digital recorder keeping away from 0dB is important.

Sure, perhaps I should have said as high as possible without the display showing orange or red, although I can't see what harm can be caused if you hit 0dB without clipping.

Hmmm, the specs for the outputs say nominal level +4dbu and +27dbu unloaded. How does that translate into the input level on the Dev measured in Vrms?

No typo's and you mean you can select both +4dBu and +27dBu?

If so +4 dBu = 1.227652988 Vrms and +27=17.341059368.

True at 0dB there should be no problem. OTOH unless you have a source of music which you know is the absolutely highest level which will be input into the Devialet there is no way to know how close to clipping you will be.
With 16-bit converters there is not a huge amount of spare dynamic range (though only between music and silence, 16 bit is plenty for most musical dynamic range). With 24-bit converters in the Devialet there is plenty of dynamic range so no need to risk getting clipping.
