Subwoofer connection to 201e

Hi

I am trying to connect a couple of active subwoofers to my Rose 201e. I have connected them to the pre outs and activated these in the menu for the 201e. No base is coming through the subs though. Are there any further settings in the 201e that I should be setting up to enable the subs to work.

Sub, runs perfectly here, from day one of setup.

On Rose RS512
