(1)-2. External equipments are connected via 10-pin connector (PORT2).
(2). Output PORT
(2)-1. DIT functions of the AK4114 (U3) are used. (Default)
(2)-2. External equipments are connected via 10-pin connector (PORT4).
[4] Set up jumper pins and DIP-switches of evaluation modes. (Refer to the following.)
[5] Power on.
Power down reset of the AK4126 (U1), the AK4114 (U2) and the AK4114 (U3) should be done once after
power on. Method of power down reset of them is that after once put them on power-down bringing toggle
switches SW6 and SW8 to “L”, release them from power-down bringing toggle switches SW6 and SW8 to
“H”.

„ Toggle Switch Operation
Upper side is “H” and lower side is “L”.
[SW6] (PDN-AK4126): Power down switch of the AK4126 (U1).
The AK4126 (U1) should be reset once by bringing to “L” upon power-up.
Keep “H” during normal operation.
[SW7] (SMUTE-AK4126): Soft mute switch of the AK4126 (U1).
Output of the AK4126 (U1) is soft-muted by bringing to “H”.
[SW8] (PDN-AK4114-RX/TX): Power down switch of the AK4114 (U2) and the AK4114 (U3).
The AK4114 (U2) and the AK4114 (U3) should be reset once by bringing to
“L” upon power-up.
Keep “H” during normal operation.
„ LED Indication
[LED1] (UNLOCK): Output of UNLOCK pin of the AK4126 (U1).
Turns on when PLL of the AK4126 (U1) is unlocked.
[LED2] (INT0): Output of INT0 pin of the AK4114 (U2).
Turns on when the AK4114 (U2) is unlocked.
