Except for the premise that there is stock, you need to make reservations. Friends who need to buy it, please be patient!If you take a photo of the payment reservation, you will not refund the deposit; if you think the decoder is nothing more than a chassis + power supply + decoding board,Don’t think about it either, because the designer’s efforts and wisdom are far higher than the price itself!

Product desciption:

The well-received Chuangmeng C-DREAM TDA1540 dual-decoded audio fever DAC has been redesigned with the third version of the circuit as the core.

Compared to the third edition:
  1. Added power module, so that each module's power supply is independent and stable
  2. Added a delay protection circuit, delay the opening opportunity for a period of time before starting the output, which can better protect the later stage
  3. Optimized the power supply and ground wire layout, greatly improving the sound quality
  4. Re-changed and defined input and output interface, more suitable for installation chassis, size: 280mm*200mm
  5. Compatible with the third version of each module
  6. Added I2S input function, the board can directly use three-wire I2S signals (LRCK, BCK, DATA, GND)

     The results of this board (Plastic seal TDA1540+Plastic seal 5532) can approach 8K for a large foreign factory machine. Replacing the ceramic seal TDA1540D and op amp will bring greater improvements!!

   TDA1540 is a classic DAC of Philips, 14bit, widely used on CD machines 
   MARANTZ CD45 , MARANTZ CD74 ,  PHILIPS CD-100 ,  PHILIPS CD-104 ,  PHILIPS CD-200 ,  PHILIPS CD-202 , PHILIPS CD-204,  The shadow of 1540 can be seen on PHILIPS CD-304 and other machines. Its simplicity and refreshing performance once fascinated a generation. Because the TDA1540 is an early DAC chip and its audio data streaming requirements are relatively special, so few people now use it to make independent DACs and can only be used on original CD machines. Isn’t that a pity... After a period of research, the webmaster used CPLD to reorganize the audio data stream and make a circuit that can drive the current digital chip. So this work was created.
