„ Operating sequence
EVALUATION BOARD MANUAL
(1) Set up power supply lines.
[+12V] (Orange) = +12V
[-12V] (Blue) = -12V
[AVSS1] (Black) = 0V
[AVSS2] (Black) = 0V
[DVSS] (Black) = 0V
[PVSS] (Black) = 0V
[HVSS] (Black) = 0V
[DGND] (Black) = 0V
Each supply line should be distributed from the power supply unit.
(2) Set up evaluation mode and jumper pins. (Refer to the following item.)
(3) Connect cables. (Refer to the following item.)
(4) Power on.
The AK4683 should be reset once bringing PDN (SW3) “L” upon power-up.
(5) Set up control software registers. (Refer to the following item.)

1. Connection of connector
In case of digital input through RX0, optical connector PORT5 (TORX176) or RCA connector J14 (RX0) are
available. In case of digital input through RX1, RX2 or RX3, only the optical connector PORT5 is available.
2. Setting of jumper pin
RX0 and RX1-3 should not select optical connector at the same time.
In case of digital input through RX1, RX2 or RX3, set jumpers JP32 (RX1), JP34 (RX2) or JP36 (RX3) as Table
2. Set unused channels to GND.
