Volume control at WiiM Ultra vs DAC

[Agentcooper1979]

Hello! I’m considering using the sub output of the WiiM Ultra to control, well, my sub! Then using the USB output to my DAC. In this instance, volume would need to be controlled at the WiiM vs my DAC/pre.

So, the question is, as a result of managing volume at the WiiM, is bit rate reduced going to the DAC? Is this a problematic setup I’m suggesting?

Welcome.

The bit rate shouldn't be affected, but the bits will necessarily be modified to alter the volume.
Many would argue that this is the only/best way to integrate a sub so that its volume changes along with the main speakers when using the ultra for volume control.
Many would then argue for hours over where volume control should occur, but imo no, this is not a problematic suggestion.
You have the choice, so try all ways and see which works best for you, for both sound and convenience, thus overall enjoyment.

I don't think usb and sub out has quite been released yet? Not got a sub, so haven't been paying too much attention! Expected within the next week or so, iirc.
