2. BASS ADJUSTMENT

Bass adjustment can be made by changing the values of the capacitor connected between BL1~BL2 and

BR1~BR2. Please refer to Fig.7.

The larger the capacitor value used, the frequency response curve shifts down. Like wise, the smaller the

capacitor value, the frequency response curve shifts the opposite direction. In Fig.7, at 9dB different capacitor

value exhibit different frequency responses. A capacitor with a value of 0.1µF has smaller frequency response than

0.56µF capacitor.
