The D/C Pin is used to select the mode of which the 3D effect function is activated. PT2386 provides two ways to activate the 3D effect function, namely: Direct or Cyclic Mode. CYCLIC MODE When the D/C Pin is connected to VDD, the Cyclic Mode is selected. Please refer to the diagram below. 1 LIN LOUT 18 2 RIN ROUT 17 3 BL1 P1 16 4 BL2 P2 15 5 BR2 6 BR1 P4 13 7 REF DBS 12 8 GND 9 VCC PT2386 VDD 3D SW P3 14 3D 11 VDD 470Ω 3D LED D/C 10 The 3D Switch toggles between activating and deactivating the 3D effect function. Under this mode, a 3D LED Display Indicator can be connected. When the 3D effect function is enabled, the LED is displayed. To make sure that the 3D effect function switching operation will work properly, the 3D pin trigger voltage value must not be less than 0.9VDD.

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.

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”.
