493.0. "Visual display of error correction?" by CASEE::CLARK (Ward Clark) Wed Oct 15 1986 10:48

    The discussion about disc dampers (491.*) makes we wonder whether
    there are any CD players that provide a visible indication of digital
    error correction.
    
    I think that it would be handy for diagnosing both disc and player
    behavior/problems to have some sort of front panel display that
    indicates when error correction is taking place and how severe the
    errors are.
    
    Such a player could easily demonstrate whether the disc dampers
    are a hype or a remedy.

    A long, long time ago, in a notesConference far away....
    I remember reading about our own CD operation having such an
    output but be damned if I can recall where...
    Hmmm.

    The Meridian Pro and Cambridge machines have it.  Its an easy logic
    signal to find in the 14-bit Philips machines (both soft and hard
    errors).

    Buy the MacIntosh CD player, it has an LED on the front that indicates
    an error correction is taking place.
