PARAMETRIC EQUALIZER
7
The PARAMETRIC EQUALIZER is based on 2 potentiometers − LEVEL and
FREQUENCY. The EQ is set to work in range between 120Hz and 4KHz .
The LEVEL potentiometer is responsible for amplifying or cutting out selected
frequences chosen by FREQUENCY pot. When LEVEL pot. is set in 12 O’clock
position the EQ is “flat” and does not change the sound. The EQUALIZER’S
operation is illustrated below.
