I Definition of cut-off frequency for Tone Control Cut-off frequency for Tone Control is adjustable with changing the capacitor C1, C2 in below circuit. See the next function for the cut-off frequency. LTIN/RTIN LTOUT/RTOUT Tone Control LTC/RTC LBC1/RBC1 LBC2/RBC2 LBC3/RBC3 C2 10uF C1 4.7uF
EX)
C1 =10uF, C2 = 680nF Cut-off frequency for Treble = 3.9kHz Cut-off frequency for Bass = 238Hz 2) BASS =+/-10dB
1) TREBLE =+/-10dB
