Here it is:
pcm.xfi
{
        type hw
        card 0
  channels 6
}

ctl.xfi
{
        type hw
        card 0
}

pcm.ch51dup {
         slave.pcm "plug:lowpass51"
         slave.channels 6
         type route
         ttable.0.0 1
         ttable.1.1 1
         ttable.0.2 1
         ttable.1.3 1
         ttable.0.4 0.5
         ttable.1.4 0.5
         ttable.0.5 1
         ttable.1.5 1
}

pcm.lowpass51 {
    type ladspa
    slave.pcm default
    path "/usr/lib/ladspa"
    plugins {
        0 {
            id 1098 # Identity (Audio) (1098/identity_audio)
            policy duplicate
            input.bindings.0 "Input";
            output.bindings.0 "Output";
        }

        1 {
            id 1672
            policy none
            input.bindings.5 "Input";
            output.bindings.5 "Output";
            input {
                controls [ 120 2 ]
            }
        }
    }
}
