D400 blinking db light (orange)

[David A]

I just took a look at the web page for the phono cube. It looks like it's a phono stage and if it's a phono stage you don't want to configure the Devialet's analog input as a phono input, you want to configure it as a line input. You don't need to worry about RIAA equalisation because the phono cube will already have done that, and boosted the cartridge output so that it is suitable for a line input. All you need to do is to match the max level setting in the Devialet's line input options to the output of the phono cube. Keep increasing the max level setting until the orange blinking light goes away. Unfortunately the web page for the phono cube doesn't give an output level spec or you could use that as a guide.

The Devialet settings shown in the photos above assume you're connecting the cartridge output directly to the Devialet and they are intended to configure the analog input to do the work of a phono stage but that is not necessary if you're connecting the output of a phono stage to the Devialet. The output of a phono stage is intended to go to a line input, not another phono stage input, and if you feed the output of one phono stage into a second phono stage you are going to overload the second phono stage, hence the orange blinking light. Increase the input setting until you don't get the orange blinking light. That light tells you that the input setting is too low.

So you have 2 options. Use the phono cube and configure the analog input on the Devialet as a line input, adjusting the max level setting as necessary to match the output of the phono cube, or don't use the phono cube but connect the cartridge output to the analog input on the Devialet and configure the input as a phono input as shown in the photos above.
