Hi
Recently purchased the M1S and I'm a little confused about the USB Audio options.
Under System Settings > USB Mode there are 3 options (the first two I understand):
- USB Storage (i.e. when connected to PC / laptop)
- USB DAC (when connected to a laptop for using as a DAC)
- USB Audio (I can't see it in the manual)
You can select USB DAC or USB Audio (it's either one or the other)
Under playback it has a "digital output" option.
So it looks like you can transmit audio data from USB but does that mean you can go from USB Audio to RCA (if digital audio isn''t selected, and if it is you can feed signal digitally to a DAC)?
i.e. What is the purpose of the USB Audio? Is it basically a digital line out for DAC/Amps that have a digital USB input? So rather than use the DAC in the M1S its sending Digital to Digital for a DAC in the amp or a separate DAC ?
Thanks and please forgive my ignorance (I'm from the old world of line outs and RCA cables).
Finally, my other question is about the gain option:
If I'm using the Line Out option from the 3.5mm output to RCA into a Class D amp, I assume I want to have Gain on Low (not High). Is that correct?
Any and all help much appreciated.
Cheers,
C.
UPDATE:
Forgot the 3.5mm output can output digital via coaxial. So I'm guessing that's what the "digital output" in the playback settings is referring to. So, I'm assuming the USB Audio is a kind of "digital line out for DAC/Amps that have a digital USB input? So rather than use the DAC in the M1S its sending Digital to Digital for a DAC in the amp or a separate DAC ?" If that's the case do
USB-C to RCA cables work in such a scenario? As you can see, I'm confused.
