In case you've used your monitor outputs on your console for a headphone Amp & you need one Aux bus to send a signal to a separate monitor on the ground, you will only be able to use mono effects in your mix using Aux bus two. I would advise you to use the headphone output from your sub mixer to feed your headphone amp.
You may also connect your effect using an insert cable so that it works dedicated only on one channel
