1) Set up the power supply lines. This connector should be connected. AK5386 is supplied from regulator T1 and T2. In this case, JP3 and JP4 should be REG side. T1. In this case, JP3 should be VA side. T2. In this case, JP4 should be VD side. besides AGND. In this case, JP8 should be open. Table 1. Power supply lines (Note) Each supply line should be distributed from the power supply unit. The AK5386 and AK4114 should be reset once bringing SW2 = “L” upon power-up. digital-amplifier, which equips DIR input. Nothing should be connected to PORT1 (DSP). (1-2) All interface signals including master clock are fed externally. PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to “H”.
