2008 7月-12月 第1項課程召集 - (1) 夏季 DAC 原理和製作班 (10月11日繼續組裝)

I have already deposit the money. Please check.

Can i hear the different between 3 DAC before I choose?

Thanks, then i choose 1955. Will the DIY very complex to do? I just made some electronic toy 10 yrs ago.  :roll: I am worried... By the way , is there any photo of the DAC?

KK Sir, what kind of file format is supported by the usb input of 1955 DAC? Is APE support? If yes, I want to add it in my DAC. By the way, do you have any balance cable (finished) for sales?

Deposit in class? Paypal?

I prefer 選擇1: 9月11日 晚上7:30-10:00

I am the student that require the assembly service.  When should I come and test the DAC? By the way, I have ordered
the usb module. Will you assembly it all together?

interesting information

KK Sir, I have a question:

The config of Our 1955 board is 平衡的結構  
What is the different between RCA and balance 輸出? Is the balance 輸出 better than that of RCA 輸出? Is our current config optimise for balance 輸出?

If a person only use RCA 輸出, then there is no need to set 平衡結構? And then 改為非平衡的結構，拆掉R404/R432/R430/R431，R504/R532/R530/R531，補上R422/R423/C421，R522/R523/C521，並修改部分電阻電容的數值?


I am interested in the TCXO module. What is the price of  TCXO module?
