PROCEED PDP 3 User Manual page 3

6 emphasis LED
This LED lights when the PDP 3 detects recording pre-emphasis in a
digital program, and subsequently employs its de-emphasis
circuitry.
NOTE: The de-emphasis circuitry of the Proceed PDP 3 is designed
to be compatible with all known digital standards. Under certain
conditions, however, the emphasis LED will light in error (that is,
when the digital program doesn't contain recording pre-
emphasis).
This isn't a malfunction of the PDP 3. Rather, it's the result of
incorrect signals generated by the program source's transport.
Depending on your transport and how you operate it, you may
never see this condition. Even when the condition exists, it has no
effect on sonic quality.
