3D BASS BOOSTER

The 3D effect function and the bass booster feature can be activated at the same time. Please refer to

The bass booster level can be adjusted by changing the values of the external components

(resistor/capacitor) connected to the Bass Booster Pins (BL1, BL2, BR1, BR2). If the value of the

resistors connected to BR2, BL2 are decreased, the Bass Booster gain will increase. The typical

resistor value is 15KΩ.

Decreasing the value of the capacitance connected to BL1, BL2, BR1, BR2 will increase the bass

booster frequency range. Please refer to the diagrams below.

In order to avoid output clipping, it is recommended that the input signal be limited when the bass

booster function is enabled. If the 3D function is switched ON and the bass booster function is not

needed, then the bass booster pins -- BL1, BL2, BR1, BR2 must be “open”.
