„ Description
Figure 2. AK7780 Board Diagram
(1) AIN/DAC/ADCM
RCA Jack. White is for Lch and Red is for Rch. Yellow one is for mono input.
(2) Optical In
Optical input connector. It supports sampling frequencies from 32Hz to 48Hz. It is used as digital data source for
AK7780. When AK7780 is operated in slave mode, this input signal is always necessary.
(3) Optical Out
Optical output connector. It can be selected from SDOUT1-6 or ADOUTA1.
(4) Power Supply
Supply +12V, GND, -12V for each terminal. Current consumption is about 500mA in operation.
(5) Clock (jumper)
Clock source jumper. Select clock source between “EXT” and “XTL” for AK4114 or AK7780.
(6) Other jumper pins’ setting
According to Table 1. / Table 2.
(7) PC/IF
Connect to PC printer port (Parallel port) with attached cable. Input signals are pull-upped with 10k-ohm resistance.
Output signals are 0-5V swing.
