Donde zz 409 2 2 6004 Figure As be seen in the Figure however the synthesized sub harmonics are not generated in the Low harmonics band with the same amplitude but with a Peak on 65Hz or on 90Hz and then with decreasing amplitude going up from 65Hz 90Hz to 250Hz and down to 20Hz 20 This is due to the fact that to extend the same amplitude to the all sub harmonics generated would bring a booming and dark result where having a Peak the 65Hz 24 36 or 90Hz 36 56 will leave the max intensity of the synthesized sub harmonics in correspondence of the original fundamentals ranging around 130Hz and 180Hz where typically is the octave used by instruments such as the Bass or Kick Drum creating a bigger presence and giving the music that much sought after punch The available Parameters of the Sub Harmonic Synthesizer accessible by the Unit s Front panel Using the NAVIGATION encoder for scrolling and the PARAMETER encoder to set their value are Percent With this parameter can be set the amount of Sub Harmonics generated that will be added to the original Signal Freq this parameter selects the Peak of the Synthesized sub band when selecting 24 36 the Peak is centered on 65Hz and the max amplitude is 18 6dBu When 36 56 is selected the Peak is centered on 90Hz and the Max amplitude is 15 7dBu Drive within this page it is possibl
