FREQUENCY sets the starting frequency of the highpass filter. Above this frequency second and third harmonics are being generated. The highpass filter can be varied between 1kHz and 7kHz in steps of 500Hz.
MIX controls the mix level between the processed and the unprocessed signal. The control range is 0% to 100%. The MIX encoder is equipped with an
Example: All controls are set to the starting position:
INPUT GAIN 0; FREQUENCY 1k; DENSITY 0; 2ND HARMONIC 0%;
3RD HARMONIC 0%; MIX 0%.
Turn the MIX to 50%. You will hear an increase in high frequencies above 1kHz due to the starting position of the FREQUENCY control. Until now you have not yet added any harmonics. The increase in high frequencies is a boost of all frequencies above 1kHz. You can change the starting frequency by turning the FREQUENCY encoder clockwise to higher frequen- cies. For some applications this may already do the job.
To add harmonics set 2ND HARMONIC to 50% and 3RD HARMONIC to 30%. If the audible effect is very subtle increase the DENSITY setting to 1 or 2 (details see DENSITY, 7).
The 2ND HARMONIC encoder controls the intensity of the added second harmonics which are being generated above the adjusted highpass frequency (see FREQUENCY, 3).
The second harmonics are even harmonics which bring a soft and silky
