Topic: USB Player Pro and DSD Direct

Greetings,

My Pro FS R BE has the following settings

1. Direct DSD 1/2 ON
2. DSD Detection ON
3. CC-mode Stereo

When playing DSD64 track from USB Player Pro from Android phone, I could adjust the volume from my amp. I thought in Direct DSD one can't adjust the volume? So it's playing using DOP?

The DAC output connects to the amp using XLR (from DAC) to RCA (to amp).

According to USB Player Pro web site, it does support DSD natively.


Support for DSD
if PCM audio is not enough
When you have a DAC capable of DSD (Direct Stream Digital), you can even play DSD (.dsf/.dff) files natively, providing a 1-bit digital stream (over PCM using the DoP protocol) like the Super Audio CD of past times! This format is now becoming increasingly more popular among audiophiles surpassing the quality of PCM audio streams. USB Audio Player PRO will convert the DSD stream to PCM if your DAC does not support DSD natively.

Re: USB Player Pro and DSD Direct

The amp is indifferent to what signal you feed it. The output is analog in any case. DSD native only means you can not adjust the volume on the ADI. Also I am not sure if XLR to RCA is a good idea. Maybe someone has more info on this. Anyway there won't be a benefit if your amp does not support xlr input, so maybe just use the rca...

Helohe is correct.
There’s no point in xlr to rca.
Xlr should be xlr all the way.  Balanced.

You could be sending 4 v xlr to 2 v rca.

Re: USB Player Pro and DSD Direct

Thank you.  Yeah, my amp unfortunately doesn't have XLR input....

Hope y'all won't mind me piggy bag another question...I don't recall the green bars this high when it's idle (nothing is playing). Is this noise/electric interference?

Explained in the manual, chapter 'Noise Levels in Hi-Speed Modes'.

Re: USB Player Pro and DSD Direct

It’s OK to use a XLR female to Cinch audio cables as long as they’re wired according the advice in ADI-2 Pro’s manual page 69:

The XLR outputs do not operate servo-balanced! When connecting unbalanced equipment, make sure pin 3 of the XLR output is not connected. A connection to ground might cause higher THD (distortion) and power consumption!

KaiS, a bit off topic here. For my DAC, if I connect the DAC XLR output to XLR input of an Amp, I can just use any commercial available XLR to XLR cable and no need to take care of the pin 3?

Yup, e.g. an XLR cable for mics.
Doesn't need to be very expensive but I would use a cable which has good neutrik XLR plugs.

R.g. this one: https://www.thomann.de/de/sommer_cable_ … r_sw_3.htm

Yes, Ramses it right.
A bit misleading “XLR cable for microphones”, as XLR cables are not specialized for anything, if at all for heavy duty stage use, which is not your use case.

Ramses link supplied is one of my recommendations too.
Buy at a Pro-Audio shop.
