audio system. Therefore, it is easy to evaluate the sound quality of AK4341. Figure 1. AKD4341-SB Block diagram COAX is recommended for an evaluation of the Sound quality.

(J8) Black 0V GND This jack is used when the ground is separated. Please set 0Ω jumper of R28 from R31 properly. Table 1. Set up of power supply lines Each supply line should be distributed from the power supply unit. The AK4341 should be reset once by bringing SW3 (PDN) “L” upon power-up.

Table 3. SW2 setting

The frequency of the master clock output is set by OCKS0 and OCKS1 as shown in Table 4. Table 4. MCLK Clock SW3: Reset of AK4341. Select “H” during operation. SW4: Soft-mute of AK4341. Soft-mute is executed during pushed. JP1: Output level of AOUTL/AOUTR pin of AK4341 can be selected by jumper pin JP1 (GAIN). Table 5. Setting of output level of AOUTL/AOUTR pin of AK4341
