I have the Vanity 103 HD board, which has four filters. I was unable to find anything on the forum about what these filters do. Other than the user guide saying #1 and #2 being sharp rolloff and #3 and #4 being slower rolloff. Are there any descriptions available as to what these rolloffs are? Corner frequencies, Db/Octave, etc. Or, maybe some graphs?by Genoaz - Vanity103HD & Lite (discontinued)
