Can you now safely use the XLR + RCA outputs simultaneously (with USB input)?

(The older development thread said no I think.)

What about XLR analogue + coax digital outputs simultaneously (with USB input)?


[I notice the big brother SGD1 can use XLR and RCA together at the same time, plus it has a remote but it is twice the price.]

That did not change anything - I already have installed what the website mentioned.
OK, here's what I've got working. I'm including images with the pertinent parts pointed out. I hope this helps you get going.

Yes, according to their website:

"Analog balanced XLR and single-ended RCA outputs can be connected at the same time,The The two interfaces can be simultaneously connected to their corresponding power amplifier devices (amplifier/power amplifier)."

I have the USB out to my stereo preamp and the XLR out to my headphone amp. I use them simultaneously when mixing music. I turn down the preamp volume when listening to the headphone amp and turn down the headphone amp volume when listening to the stereo. So far no problems. If you want to load both at the same time (like to power two amps at the same time), you might have to be the pioneer and let us know how it goes. I have had both amp and preamp running for short periods of time with no issues.

Great, thank you. I am comparing this and big brother SGD1 for direct connection to my Genelec 8030s (and another line-out to my kitchen powered speakers.)

I guess in the development they didn't have separate op amps for the 2 outputs or something. I guess simple line-outs don't bear big loads if they are designed to usual standards (?)

Did anyone try to use this DAC with one of the typical Raspberry Pi power supplies?
They are rated at 5 or 5.1V and 3A and (thats the reason I'm considering it) they usually have an ON/OFF switch just behind the usb connector.
I'm thinking about getting this DAC but I need an option to turn it on and off without too much hassle.

I use the basic Raspberry Pi power supply with no switch. It's a great supply. Leaving this DAC on is your best best if you can set it up that way.

Try the older version.
Now i switched the volume to max. I can hear some music now. And bingo: The old sacd-plugin did it.
Any way to get the volume down? It's far to loud at maximum volumen.

If you are in DSD output mode here

it shouldn't play a .dsf file at all in PCM mode. Try uninstalling new decoder and installing older version. And try messing with Windows "select playback device" in the bottom right hand corner device.

Can somebody explain, what the "output mode" "PCM" really does? Is it true, that the quality would be the same in result (because my soncoz does the conversion?) but would be Volume-controllable?
