86.0. "Techniques SLP-3" by XENON::MUNYAN () Tue Feb 12 1985 20:21

Has anyone heard or seen this unit?  I've heard that it's the best in the
series that Techniques just announced.  I've sent away for more information
on it.  According to the advertising literature I'd seen on it, it claims
to have some sort of special firmware that lets it properly play back CD's
that were recorded with "Emphisis".

From what I could gather a good number of the CD's that people have been
reporting as "fair" to "ok" CD recordings were actually recorded this way.
It further explains that without this special decoding you will get a hiss
in the background or not get the full impact of the highs and lows.

Does this sound right or is it another line?

When I get the actual literature I'll add more details...

I have the Technics SLP-8, don't know about the 3 except that it is not quite 
as stable tracking wise as the 8 .  The performance and features on the 8 are 
great, I think the 3 has the wireless remote, doesn't it ?  I am very pleased 
with the 8, no complaints, it can be gotten at discount as well .

86.2Pre-emphasis on SL-P3CHECK::MWRESINSKIWed Aug 06 1986 12:1524
    Although the original note was from '85, I'm new to this file and,
    since there was no further info, I'll offer this from my SL-P3 manual:
    
    EMPHASIS INDICATOR:
    Illuminates when a disc containing *pre-emphasis* is played.
    
    *Pre-emphasis*
    In order to further improve the S/N ratio of compact discs, some
    discs include a degree of emphasis in the high frequency range called
    pre-emphasis.  If these discs are played without any compensation,
    the high frequency range will be unnaturally strong.  Therefore,
    a corresponding amount of de-emphasis is needed to obtain the proper
    response.  The de-emphasis circuitry of this unit is automatically
    activated when a disc having pre-emphasis is played. 
                                                         
    
    I received the player last Christmas, but I believe it has been
    replaced by another model number.  The unit is feature-loaded. 
    
    The only quibble I have is that, ocasionally, when going directly
    to a track after inserting the disc, it seems to miss the first
    fraction of a second of that track -- as if the beam had over-scanned.
    Could this be because the beam picked up the first "groove" in 
    mid-rotation?
