J1000 DELTA is a mixing EQ with a twist. It shares the same HP/LP and output section as Beta. The obvious differnce is the way Delta handles audio via it's tilt and concurve modules. Actually, they are just pairs of filters that are set to work parallely. In case of tilt when one filter goes up, other goes down. Since their central frequencies are far apart (at default they are 50Hz and 10.5kHz), it results in spectrum tilting. Horizontal fader [F] controls central frequency of tilting, where gain remains zero. In case of concurve, which name derives from convex/concave curve, both filters react the same way, so when you move [C] fader up the spectrum "smiles" :), and when you move it down it "frowns" :(. Loudness difference is automatically compensated. Horizontal fader [Q] adjusts bandwidth of opposite filters. Delta is suitable when you want to preserve the natural color of instrument, optimize it's presence in the mix and, figuratively speaking, adjust it's brightness and contrast.
