• Manufacturer: SILAN [Silan Microelectronics Joint-stock]

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
capacitor value, the frequency response curve shifts the opposite direction. Please refer to the diagram below.
In the diagram above, at 9 dB – different capacitor values exhibit different frequency responses. A capacitor with a
value of 0.1 f has smaller frequency response than a 0.056 f capacitor.
