Hello,
I have tried to install ZAPfilter from LC Audio (http://www.lcaudio.com/index.php?page=6) in Philips DVD963SA according to connection diagram in LC Audio website (diagram 2, for differential current output DAC):
http://www.lcaudio.com/index.php?page=43
DAC is AD1955 (differential current output) in DVD963SA.
AD1955 data sheet:
http://www.analog.com/UploadedFiles/Data_Sheets/422968845AD1955_0.pdf
It seems to be OK, but signal output level from installed ZAPfilter is very low (comparing to original analogue stage).
Any ideas how to solve this problem?
Is it DAC mismatch with the connection offered in LC Audio website?
Original analogue stage in DVD963SA player is similar like shown in data sheet for AD1955 (fig.9).
Thank you beforehand.
