Directly pick up the signal from the DSD DAC chip with the voltage in
---------------------------------------------------------------------------------------
When I just connect one channel for the input on the Zapfilter. It works fine! But after the input for the both channel the pulse noise comes out! I think maybe the groud looping on both channel so I try to flow up the group for both channel for the test on it. The noise still comes out! What happen on it? Is it becoz on the design of the zapfilter?
But I think the signal which I pick up not the complete wave form... I just pick up the signal from the CXA8042 pin 1 and 2 only to the zapfilter + and - ! What should I do? Thanks!
Please advise!
