Hi all:
I tried to install the LCaudio Zapfilter mk2 on the DVP-S9000ES last night. I found that this DVDP using the CXA8042AQ. Ofcoz I cant find any datasheet for it. But I've got some info about this. I follow the info and replace the 1.5K resistor on the pin19 to 3K which for adjust the output current of the DAC...
Then I tried to connect the output direct to the Zapfilter in the current in mode. It cant work..... actrally I found that there have 4V output from the positive and netgative from the output of the CXA8042... and the zapfilter have 8.2V-8V output......
Then I tried to add on the 10ohms bewteen the output of the 8042 to the zapfilter.. also cant work.... when I connect the 8042 back to the I/V of the 9000ES... it becomes normal again...
Question is how can I using the direct output to the zapfilter working at the current input mode? Is there have some tweak or special connection of this to zapfilter?
Actrally I tried to connect the input to the zapfilter share with the I/V satge.. it is not enough gain and seems cutoff the bass..... Any solution on this.... Or I have to connect this in voltage mode after the I/V stage from the 9000ES to zapfilter?
I know it will work but it is not the best way to use the zapfilter.... please advise. Thanks!
