Keep in mind that these "electronic" gain controls will only show up in the DSP PC-Tool application if you go to the DCM screen and "enable" the "Source Volume Control" setting.I'm not sure why I never seen or read into this before, but this totally makes sense and is something I need to look into.
Currently using Optical from an AP4 to DSP.2, and noticed that when setting the gains I was able to crank them pretty good. One thing I noticed too (outside of the slight noise I have with no signal playing) is that my system still has noticeable volume even at the lowest setting on the HU. My guess is that this is due to the relatively high amplifier gain I'm using with the current 0.0dB setting on the digital input?
Was unaware of a Helix app... Gotta link or what's it called? ThanksWhich DSP do you have? WIth the newer ACO-based DSPs, there is a mobile app that allows you to adjust all of the volumes. Check the volume levels in the app to make sure they are appropriate. You may just need to turn the master volume all of the way up in the app to get things working like you want with the URC-3.
When I first installed my DSP.3, I had to install the app in order to get ANY sound - found the "Master" volume was all of the way down in the app (I don't have a URC connected)...
You’re not quite correct, a digital signal in itself doesn’t clip as it’s at 0db at all times unless a volume control is present on the source in which bit depth is reduced to attenuate volume, hence people saying it will never clipThanks for the reply! I went ahead and maxed mine at 10db but then thought I better find out for sure. I have plenty of volume and zero clipping. I'm kind of wondering why there is even a setting if a digital signal doesnt clip?
Set digital volume in the software... this is how it needs to be for best signal to noise... and use master volume and sub volume on the urc.3 as that will also control any digital sources also at the output of the processor where you need it... master vol is just that, it controls the output of everything, if you’re playing a digital source the Master volume will effect it, I don’t see the benefit of digital volume at allRegarding the digital volume... I originally assigned remote #1 to digital volume and #2 to sub level. I had almost no volume. Then I changed #2 to master volume. Then I had full volume and both knobs adjust the volume.
Which is pointless... How can I use sub level while using digital volume?
When you say, "Set digital volume in the software", do you mean in the IO page that we discussed previously in this thread?Set digital volume in the software... this is how it needs to be for best signal to noise... and use master volume and sub volume on the urc.3 as that will also control any digital sources also at the output of the processor where you need it... master vol is just that, it controls the output of everything, if you’re playing a digital source the Master volume will effect it, I don’t see the benefit of digital volume at all
Set the outputs to match the analogue output (whichh will have been clean due to scoping it) so you get full volume by both inputsThanks for the information! Doug also mentioned to me that digital sources are often lower db. I'm new to using a digital source and still learning.
I'm currently using a Filo x5 line out directly to the Helix RCA input. This is temporary until I install a coax to optical converter.
I have a mixture of 320 MP3's and 24 bit FLAC. What is the best method to properly set the input gain?
