5-Mode Preset Equalizer IC with Bass Booster & 3D Effect
BASS ADJUSTMENT
Bass adjustments can be made by changing the values of the capacitors connected between BL1
-- BL2 pins, and BR1 -- BR2 pins. The larger the capacitor value used, the frequency response
curve shifts down. Likewise, the smaller the capacitor value, the frequency response curve shifts
the opposite direction. Please refer to the diagram below.
