Roon zone grouping with 2 systems in the same room (stereo + subwoofer)?

[Menzies]

I think you’d need an endpoint with multichannel functionality, connected to something with multichannel functionality.

This has been discussed in other threads and Roon’s Danny said this.

Is it possible to connect two USB DACs to one computer and group them in Roon to output at the same time?

yes

@David_Ting

I want to connect one DAC to the amp and the other to the active subwoofer. Will this cause any problem?

While the zone syncing is good enough for multiple rooms, it’s not good enough to do sync between channels. You will probably get drift and this will not sound right.

@David_Ting

I simply want to add some bass to my system where no subwoofer output is available.

You will need to run a cable or use a speaker/sub setup that supports wireless sync that is meant for this.

@mitr

are you doing bass management in Roon and sending different channels to the two DACs?

I know @mitr is familiar with this, but for everyone else, this concept is basically making Roon be the crossover by using Roon’s DSP and channel routing .

This requires a multichannel sound device to pull off, but the flexibility and control you get in this approach is awesome.
