Yes you are right. In your case, this is the effect of the reflected signals on the line.
But I had no such problems. It was made 3 copies, and they had no noise.
Could you show a photo of your board?

Howdy All,

Looking for some input on power supplies for a DSC2 V2.5.2 build. Looks like I need 5V for Amanero, and the same for each channel on DSC2. I also need a +/- 18V bipolar supply for my output stage. It would be nice to have each supply on its own PCB including the transformer. Anyone have any recommendations? I’m in the US, so 120V mains. Thanks for any ideas or pointers!

My apologies if rhe following question has been alredy made.

My setup is a dsc 2.6.2 with amanero firmware 1099c. I play music in my home network with HQPlayer and a raspberryPi3 with DietPi. Amanero is connected to the Pi via USB.

That setup plays beautifully but I have a huge blop (or click) whenever the family rate changes (say playing 44.1khz music file and thereafter 96Khz file). It also has that problem with native DSD files which have different family rate.

Does anybody have a similar problem ? How did you solve it ?

Cheers

Tested my DSC2.5.2 with resistance installed on R65 R129 ... then rolled back to default configuration. An oscilloscope is probably needed for a real fine tune ... I will try to buy a decent one.


Question. I use BeagleBoneBlack as a NAA. What should be the right set for the parameter <DAC bits> on HQPlayer? 32, 24, Default?

Does someone know a place where I can get genuine old Philips or NXP 74AHCT595?


+What is the most acceptable substitute for old 74AHCT595? Nexperia, Diodes Incorporated, Texas Instruments, or a different brand?


I would especially be interested in a reply from Pavel, but anyone's help is greatly appreciated! -Thanks in advance!

I'm considering giving the DSC2 prototype a try. What Voltages DC do I need to supply?
5VDC for the Amanero, but what about the DSC2 itself?
