This corresponds to a ratio of 1\/100 compared to 1\/16 (+\/- 12dB) available on almost all other equalizers and filterbanks. So even drastic sound manipulations are possible that normally require two chained EQ´s. The q-factor of the filters gradually increases from 0.7 at +\/-10 dB to 6 at +\/- 20 dB.\u003c\/span\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\" colspan=\"5\" style=\"width: 23.4531px;\"\u003e-\u003c\/td\u003e \u003ctd width=\"685\" style=\"width: 538.047px;\"\u003e\u003cspan style=\"font-family: Times New Roman, Times, serif; font-size: medium;\"\u003eThe individual filters are not decoupled from each other. Thus all kinds of - wanted - phase changes and cancellations occure. Normally this circuit design has the disadvantage of a very non-linear control curve (all relevant changes happen within a few degrees at either end of the pot´s turn). To compensate this, sealed high quality pots with a special curve are used, custom-made for us by ALPS.\u003c\/span\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\" colspan=\"5\" style=\"width: 23.4531px;\"\u003e-\u003c\/td\u003e \u003ctd width=\"685\" style=\"width: 538.047px;\"\u003e\u003cspan style=\"font-family: Times New Roman, Times, serif; font-size: medium;\"\u003eInput gain and output level controls.
