[I edited this to include a screen of my signal path with DSP Volume engaged] So I’ve now had Roon running for 3 months, and I love it. What I don’t like is how I have to control volume in my setup. I run Roon Core on a powerful Windows machine with a Ropieeee Roon Endpoint running into my dac. I…

@danny Is there any possibility for Roon to license the Leedh volume control (digital) implemented by Lumin? It’s received rave reviews. I say this with full knowledge that perhaps I am way off base in terms of this thread! :wink:

I do use DSP volume in ROON with rooDial - I assume this is required to use the rooDial - Is that correct? ROON Support has confirmed that if I upsample using DSP I can no longer use the DSP volume control. I am not at the system now to send a screen shot.

I have a Pass Lab Preamp that controls the volume and a Denefrips Venus ll DAC. I just selected ‘Device’ control on the Devise Setup. The rooDial will respond to turning but it doesn’t change the volume when I am using DSD or anything else in the ROON DSP options. When I disable all other DSP option…

[image] DrCWO: As far as I know the “Leedh” is nothing else but the volume control of the ESS-DACs inside the Lumin streamer That is indeed incorrect. Lumin actually allows you to choose between two kinds of volume control. For analog output of X1, T2, or S1, you can choose the on-chip stan…

[image] wklie: or the Lumin proprietary Leedh implementation that takes advantage of hardware architecture (with Leedh setting on). Quite Interesting, in this case I wonder what Leedh processing stands for? I am not interested in marketing speach but in technology behind it. Is there any mat…

Hi Peter, I thank you so much for your information. I got, that needing less bits and despite of that having a perfect volume control is the idea behind Leedh volume control. great :slight_smile: I also understood the advantage of this approach implementing volume control in silicon :+1: Would yo…

If I understand this correctly, a fundamental assumption is that the least significant bits in traditional calculation, although mathematically accurate, become noise due to the DAC hardware limits. Whether this is true or not can only be verified by subjective listening tests. So far the majority…
