Hi Team,

How to adjust the output of DOUT in order to control volume? The operating system is Windows.

Thanks!

Hi,

There's no volume control for analog in as shown in the diagram below.

The FU is only on analog out.

Regards.

Hi Peter,

My question was about S/PDIF out. Looks like it's coming from the same input source as the analog outputs. Is there a way to control volume here?

Thanks!

Hi Roy,

The volume control is likely tied to the digital volume in the DAC controllable through the system volume control, this is all part of the USB protocol.

You can try, but I doubt it's controllable for the DOUT.

Regards.
