Dear improwise,

1. Yes, the EQ only work in Bluetooth mode.
2. Filters could work in Bluetooth, Optical, Coaxial mode.

Best regards

Thanks. Does this mean that filters don't work when using USB?

Yes.

I think you should highlight this more in the actual app, as I think there are many users that would imagine both that EQ works on all inputs and also filters. I know it's somewhere in the documentation ( probably) but who reads that unless you really need to?
