„ Description
(1) AIN/AOUT1/AOUT2/AOUT3(Analog Data)
RCA Jacks. The white jacks are used for left channels and the red ones are for right channels.
(2) PORT1/PORT2(Digital Data)
SPDIF-IN(PORT1) É¿ This port is only for examinations, a digital input is not available to use.
SPDIF-OUT(PORT2) É¿Optical output connector. It outputs the data from whichever among SDTO1~3.
(3) AK4114(U6)
AK4114 outputs digital data of AK7600VF as DIT on a slave mode.
(4) Power supply(+12V, -12V, +5V, AGND, and DGND)
When the regulator(REG1) on the board is used, connect to +12V, AGNDɼ-12V and , DGND, open +5V jack and
short JP18(Default set-up : Current of this normal operation is consumed about 130mA.). Otherwise, AK7600VF can
be supplied 5V power without the regulator (REG1). Connect to +12V, -12V, AGND, DGND, and +5V. And it also
needs to open JP18. (According to fallowing Table 1 and Table 4)
