I am an owner of brand new Fireface UCX and recently bought a used UFX locally.

I can easily send tracks to the Reverb and Echo and then enable the returns on my UCX. However, I do not seem to get any FX out signal on my UFX (there seems to be no activity on the FX out volume meter). Insert effects like the EQ and the Dynamics seem to work fine on both units.

Am I missing a setting or a parameter or is this a hardware issue with the UFX I bought? Any help would be appreciated.
