Illustration 4.7: Principle of the adaptive tone control
Description of the individual modes
Modes „LINE" / „MIC" / „OTHER"
•
These modes incorporate a shelving tone control. In both rightmost and leftmost position the
width of the boost / cut is increased to its maximum (see illustration 4.8).
Mode „INSTRUMENT, A-GUIT"
•
This mode sets the input sensitivity and tone control characteristics to fit acoustic guitars. It will
affect the bass fundamentals between 100 and 200 Hz and the highs at 8 kHz. Turning the con-
trols towards their right / left stop will broaden the cut / boost effect (see illustration 4.9).
Mode „INSTRUMENT, E-GUIT"
•
To adapt for electric guitars the bass is shaped at 120 Hz while the mid high center frequency will
be shifted in the region of 5-7 kHz. This takes into account for the distinctive midrange of electric
guitars. Similar to other modes, in the leftmost and rightmost positions the cut or boost is
broadened successively (see illustration 4.10).
