TUNNING TONE CURVE CHARACTERISTICS
The tone control response character is possible tuned to match user’s wishes, please refer to following chart to realize
the characteristics between the different component values.
For the reasons to achieve low distortion and precision response gain, using high quality low tolerance X7R SMD
capacitor on tone circuit is recommended.
The loudness boost gain is adaptive with the master volume attenuation setting, more attenuation means more low
frequency boost, in the maximum volume the loudness boost will return to flat response.
