Disconnect CD digital output?

float · 5th August 2005, 12:16 PM

Having lost the little cap that covers the optical output on my player, I notice that the red LED thingy is constantly on.
Probably a silly question, but has anyone found disabling the digital outs to be of benefit

Could these outs be a source of noise that would be better gone?

You would have to remove the buffer (74HCU04 ?) and everything around it - optical thingy as well! Remove everything, cut the +5V tracks as close to the +5V voltage reg (source - as I call it...) as possible, and bridge all the not-needed-any-more tracks to the ground plane. RF track should also be cut 'at the source'... No one listens to 2DAY FM anyway…

Cheers EB, you make it sound so simple

Can I take it that you've thought about this yourself? Or even tried it?

The real question remains- would/does it make a worthwhile improvement?

Yes, I did this many times: not needed headphone stage in analog section of a CD Player, digital out sections not in use / needed on CD transports, obsolete tracks around removed xtals... Just make sure that tracks are not floating, but tide them to ground plane. Power supply tracks should be set free – cut close to the voltage regs + the ‘leftovers’ should be connected to ground potential!

The effort is worthwhile 100%.
