Proscenium Black Diamond Turntables and Arm
Proscenium Black Diamond
Turntable and Arm features the new
Black Diamond Air-bearing Arm and Spindle. Made of a
proprietary material, it is 20 times stiffer than carbon fiber.
So hard, only a diamond can cut it!
The Proscenium Black Diamond Turntable is the result of over
30 years of research to build the best sounding turntable possible and
it has excedded our wildest expectations.
Every component of Proscenium Black Diamond Turntable is
selected for its sonic performance. Nothing is taken for
granted; even the finished on the platter has been selected for its
sonic merit.
The table is so versatile with fully adjustable features, even
the "tweaker" serching for the ultimate configuration will be thrilled.
The system comes complete with arm, requiring only your
favorite cartridge.
Features
Air-bearing Platter
- A huge 10 inches in
diameter with 3 air jets, hand lapped.
Platter and Record Clamp
- The platter is
machined from the most resonance-free material known, pure lead, and
sealed. It is machined slighly smaller in diameter than a LP
so the the thicker outer lead in grooves of the LP over hangs and
allows the LP to lay flat, the label area is machined out wider and
deeper than most players.
The LP is heald slightly above the platter at the spindle so
when the record clamp is tightened, the record is forced flat to the
platter. The peole in Walker Audio have found this to sound
far better than vacuum hold down. Vacuum pumps are noisy and
they place this noise at the critical interface of the record and
stylus, plus any small vacuum leaks from the seals createds a high
frequency vibration that is detrimental to the music.
New! Black Diamond Air-bearing Arm and Spindle
- The arm is a true high-pressure (45 psi) low flow captured linear
tracking air bearing. The spindle and the arm are constructed
of a proprietary material that is 20 times stiffer than carbon fiber.
A simple adjustment sets the center of gravity correctly for
any cartridge. The impovement in sound is amazing.
Arm Adjustments
- Fully adjustable for VTA,
overhang, azimuth and dampoing. VTA adjustments do not affect
the others. The VTA is not adjustable during play - that
would compromise the sound. However, the VTA is easily
adjustable. The damping is adhustable during play.
Most cartridges require only a small amount of damping
playing premium records, however, lesser recordings require more
damping.
Arm Wiring
- Sourced from a bio-medical laboratory.
This is the same ultra-pure solid core silver wire with ultra
pure clear 0.001 inch Teflon insulation that i s used in medical
reserarch to connect the ear to the brain. The wires are
separated in the reinforced carbon fiber arm and directionally wired
for improved sound.
Remote Drive Motor
- Enclosed in a matching cast crushed marble enclosure, the
motor drive is mounted on
Valid
Points and sets on a adjustable motor
base assembly so that belt tension can be easily adjusted.
The drive pulley is stright cut so that any belt materials up
to 5/16 of an inch may be used. Two to four millimeter 100%
pure silk belts are supplied and preferred.
The motor is wired with silver/Teflon solid core wire, with
ultra premium foil, and solid capacitors by-passed with signature foil
capacitor. The on/off switch is solid silver. The
drive motor is an instrument grade ball bearing AC motor, and is
filtted with an IEC connector so premium power cords may be used.
Ultimate Motor Controller
- The Ultimate Motor Controller
comes with the turntable. It is 4x8x17.5 inches and comes
mounted on an eight-piece Vaild Points resonance control kit.
It features a Teflon circuit board, special proprietary nude
metal foil resisters and Blackgate caps. The motor controller provides
the motor with noise-free, accurate speed regardless of wall power
changes. It allows for separate fine adjustments for 33 1/3
and 45 RPM. A KAB strobe is provided for precise speed
setting. Speed selection is by a switch. The unit is
fitted with an IEC connector so special power cords may be fitted.
Air supply System
- It is very quite and may be placed in a
far corner of your room. However, it is recommend to be
placed in another room, if possible. Two 100 foot rolls of
1/4 OD clear flexible plastic tubing is included so the air supply can
be placed anywhere up to 100 feet away. The air supply
system is in a very attractive black oak veneer box. The air is fully
filtered, coolled and regulated in the system and the moisture is
automatically collected in a holding container.
Easy Set Up
The turntable requirees a rigid, sturdy platform that is
capable of supporting 245 pounds and at least 18 x 24 inches minimum.
The recommended width of 18 x 28 inches. Shiping weight of the system
is approximately 390 pounds. Your Proscenium Black Diamond Turntable
will come with an owner's manual that included step-by-step directions
for setting up your turntable. The table which comes with a very
easy-to-use alignment record, is designed to be easy to set and play.

Review
"Until now. Now the Proscenium has taken its performance to
another level, one that I didn't suspect existed until I heard the new
configuration. It retains all the virtues of the Gold Signature system
- complete control over all aspects of LP playback, including VTA
adjustment, tracking force, damping; adjustable leveling, speed
control, belt tension, and so on—but then adds enhanced resolution,
better detail…without losing its remarkably superior audio-musical
coinherence." - quoted from Postive Feedback Online Issue 28, The Higher End: Robinson's Brutus Awards, and the Gizmo Award for 2006
