DUDU-Meng for some reason can't send message on telegram. I logged in after a long time and not able to send a message. Can you send me a message @systele?

It's the tool from my audio interface. 1.0 is 100% = 0 dBFS

Hi . im using dudu6(m6 pro plus) and im wondering which is better to use for usb out device to connect to my dsp , USB interface for digital to digital or USB DAC which is rca IN to dsp. Does anyone tried both? which is better?

DUDU-Meng

KenMac Sorry, I don't know what M6 is. We don't have this model here.

Guys, is it just the usb-c output where you have no control over the volume or is it the same if you use either either of the usb-a outputs ?
Thanks

Chrisjohn all usb audio are taken before DSP which means no usb audio has volume control.
Volume control is available on psdif and coax which offers pass through (meaning all dsp is off). This method reaches 10Hz-24kHz (flat), over 100dB S/N and very low THD, which is excellent anyway. The max volume at 0dBf is max 0.9 though, not 1.0 (probably dsp headroom for any EQ etc which isn't switchable) but it can be easily bumped with amp gains.

That's what I thought but I have just connected my external dsp via usb-a out puts on the headunit and the steering wheel and headunit volume controls both work ???

Although when I use the usb- c output I have no control over the volume as expected.

Chrisjohn possibly this model does standard android usb audio over usb-A (like any android host device from android built in mixer and bit perfect usb audio over usbc)
Can't confirm as have Dudu7.

Chrisjohn

Mine is also dudu 7. Will try the other usb- a today.
Thanks for your input !

When I was playing from USB-C, volume controls on the handwheel did not work. I had to use my DSP controller. Never tried with USB-A.
I would like to know what's the best way to connect from DUDU7 to my DSP ? I mean Which out ?

Mitz Na ten moment dźwięk z USB do DAC to najlepsza opcja pod względem jakości dźwięku, jedyny minus to zewnętrzny kontroler głośności z DSP

True. My DSP has OTG input (USB3.0 A).
My question is which USB do I choose from DUDU7, will that be USB-A 3.0 or the USB-C from the back of head unit ? That gets into my DSP Otg input.
Which has better output?

rille

It doesn't matter which USB you use. Why should it make a difference? USB 2.0 is sufficient for stereo audio even in high bit rates.
