"The audiophile dream machine
has come to answer your prayer; but,
you may need to take out a mortgage
to bring this altar into your temple." |

|
Overall |
The
dream of a turntable that could play
individual tracks like a CD and leave
no wear on your records has long been
a standing dream ever since Edison
dropped his first track. The time
has come for this realization; albeit
not perfect, it’s the best thing we
have right now.
Using five lasers beams, two for
tracking, two for reading audio,
and one for height control, the
Laser Turntable (LT) can accurately
playback vinyl records in most any
condition. Having no contact with
the record and a optical surface
area ¼ the size of a regular
needle, the LT is capable of reproducing
sound that is close to the original.
The ELP Corporation spent over
US$20 million developing technology
that would aid in the preservation
of vinyl recorded material for the
enjoyment of future generations.
Celebrating over 1000 Laser Turntables
sold; ELP has announced the release
of its new improved model, featuring
full remote control and sonic improvements.
Prices for the new models range
from US$10,500 - $14,300. Sound
expensive? This is nearly half the
price of the original model!!
Enough said, it quite likely that
most of us will never own one of
these turntables, being priced equal
to that of a small car. But if you
ever find yourself in Ottawa, The
National Library of Canada installed
one into its Music
Division in 1991.

Appearance |
Looking
a lot like a Laser Disc Player from
the early ‘90s, the LT design is not
the sleekest. With simplistic LED
displays and minimalist push button
controls, the LT achieves a look and
feel that is truly outdated. This
comes as no surprise, as the original
model was created in 1989 and the
ELP Corporation is dedicated to keeping
its costs as low as possible while
maintaining is commitment to quality
parts and construction. ELP states
that following standard industry product
“markup would put the price beyond
the reach of many prospective customers. |
Functionality |
Having
a laser turntable makes it possible
to play LPs as one would a CD. When
a record is first loaded, The Laser
Turntable scans the disc for gaps
between recordings. The LT uses these
gaps to generate tracks; which can
be accessed with push button accuracy,
much the same as is found with CDs.
Likewise, this accessibility allows
users of the LT to access cue points,
set random playback, program track
groupings, and take advantage of the
repeat functions. The LT also offers
users the convenience of an on-screen
LED display; which, can be used to
display elapsed, remaining, or total
time. Unlike a CD player, the LT offers
adjustable rpm controls (30 – 50rpm
for LP & EP setting and 60 – 90rpm
for 78’s) in 0.1rpm and 0.2rpm increments,
respectively.
The dual optical pickups adjust to
compensate for conditions found on
damaged, scratched, worn, and broken
records. Never before has a broken
record been able to be played. The
LT glides seamlessly over breaks with
no more than a slight pop, much like
the sound produced from a minor scratch
with a standard needle. Records skips
are relatively invisible to the LT,
which plays unhindered through such
damage. The audio lasers have the
ability to read below surface abrasions
on the groove wall and return clear
sound.
In many cases the outside wall
of a records groove will wear more
than the inside, due to the constant
friction against the needle as it
is being pushed towards center.
The LT’s dual independent audio
lasers read each side of the groove
and report this audio information
to the left and right stereo channels.
This offers true stereo balancing,
without the possibility of producing
channel balance errors or stereo
crosstalk, commonly found within
stylus pickups. When dealing with
monaural recordings, it is then
possible to isolate the less damaged
signal from the inside of the groove
wall to increase your overall playback
clarity.
It important to note the LT’s reduction
in sound errors and feedback that
are commonly found in vibration-based
audio pickup systems. Acoustic feedback,
cartridge hum, and tonearm vibrations
are eliminated by the use of lasers,
which have no contact with the playing
surface. Tracking angles, leveling
adjustments, and anti-skating measure
are dynamically calculated and adjusted
to match even warped records. On
top of all this, the LT comes equipped
with a Noise Blanker feature, which
can help in the overall reduction
of unwanted playback noises.

The Laser Turntable connects to
your pre-amp from outputs located
under the FUNCTION switch, "MONO,"
"LEFT," "RIGHT."
(Input impedance 47k ohm)
Another factor to consider is that
laser diodes do not last forever.
ELP rates theirs at 10,000 hours
which is a reasonably
long time. The replacement
cost is a tidy $1500.
