Ground issue
I am modifying my Sony SCD-C555ES. In the IV and output sections, the signal input ground, the output ground, and the power supply ground are all isolated (although they are connected somewhere outside of the audio board). I cannot make much sense out of this design and believe that it creats problems for high frequency singals. Any thoughts on how to connect the grounds without creating a large gound loop?

Hi
Your observations are correct One should use a closed groundplane to avoid signal loops. On my site, I have a PDF with advise on how to layout a circuit board Currently my site is down due to hosting transfer, but you should be able to find yout way tomorrow best |
