Dear All,
The facility for a manual de-emphasis was borne out of the need to be able to allow de-emphasis on discs where there is no encoding that triggers the automatic de-emphasis.
Now you may ask, are there such CDs??
Unfortunately yes there are and quite a few (not that the record companies would admit to it off course) I have a number of Jazz and a few classical CDs all of which sound clearly pre-emphasized, but none of them trigger the auto pre-emphasis, so the manual version is pretty useful.
For normal CDs always use the direct out.
Sincerely,
Peter Qvortrup
