    Have a look here: http://www.allen-heath.com/UK/Products/Pages/iLiveTrainingVideos.aspx?TOV=1&CatId=iLiveSeries&SID=36
    It’s for the iLive but it is the same GEQ models.

    Cheers

    Constant-Q is 1/3 octave constant width with symmetrical cut/boost, ‘american’ classic if you like.

    Proportional-Q is based on accurate modelling of gain / Q relationship and band interaction in a British, industry standard GEQ. You get wide Q for gentle cut/boost, which progressively tightens beyond 1/3rd octave for higher cut/boost. Higher band interaction typically results in a smoother sum of adjacent bands when compared to Constant-Q (some describe it as warmer).

    Hybrid is an asymmetrical model which gives you the best of both worlds: boost is proportional-Q, cut is clinical 1/3 octave.

    Digi-Q offers minimal band interaction to provide a frequency response as close to the slider position as possible.

    Most people use Constant for feedback control in monitor world, and Proportional for tone-shaping, but the choice of GEQ models depends on personal preferences rather than applications. Listen to each model and pick your favourite :)

    Hope this helps,
