Made the following changes
1. The decoupling filter capacitor has been added, and it has been changed to a direct plug, which enhances the circuit filtering characteristics and improves the anti-interference ability.
2. The output digital cow has added model compatibility, compatible with SC947-02LF Super Shielded advanced digital transformer
3. Corrected the position of the screw mounting hole, which is more convenient to cooperate with the original Italian module
4. The board is still designed and processed according to the requirements of HIFI, using the immersion gold process, the chip capacitors use Murata COG X7R material, and the in-line capacitors use ELNA blue robe series capacitors
The Enhanced version has enhanced accessories over the Standard version:
The output transformer is upgraded to Murata DA101C
The output coupling capacitor adopts philips silver film high frequency capacitor
RCA sockets use full copper Taiwan high-quality gold-plated RCA sockets
The XLR seat adopts Swiss Nutrik gold-plated XLR seat
installation method:
1. Connect the 5V power cord. This power supply is for DS8921. When DS8921 is powered by 5V-7V, the effect is better
When changing the RCA and balanced mode by yourself, you need to change the short circuit on the back of the board. a. When the balanced output is used, JMP4 is disconnected, and JMP54 is short-circuited; b. When the BNC RCA is output, JMP5 is disconnected and JMP4 is short-circuited.
2. There are two superimposed installation methods, suitable for boards in different situations
Italian module top mode
No matter upper or lower, please solder all the solder joints of the pin header
The following is the installation renderings, for reference only
Many modules compatible with Italian module pin header pin functions can be used:
