studio subwoofer

does anyone know where I can learn the way to set the level on a powered subwoofer when I'm mixing?

Since it's powered, it's level is separate from the main monitors, and further complicated by the use of the LFE channel.

Pretty confusing

Well, not really.. like anything else in audio, there are reference levels. both dB and SPL. Do a search for 5-1 audio calibration parameters.
You will need a Pink Noise source generator (free in SF) and a SPL meter. (not free)
Maybe someone here can give you specific parameters. I don't have them at hand.

Are you using the sub for LFE (from 5.1) , or bass reinforcement for a stereo pair?

Crossover freq's / gain / noise & test tones / placement all factor. Is it a pro sub, or hifi sub?

It's level is not sepatate completely - you set an appropriate level on the subwoofer itself with some test tones and a level meter ( or empirically), and leave/secure it (gaffer tape ?). In normal programme playback the level is ganged with the other channel levels from the playback device volume control.
