ASSEMBLY INSTRUCTIONS
Place the turntable base on a solid audio rack or
1
turntable shelf. Please avoid shelving made of granite
or glass, as these materials resonate and amplify
vibrations coming from the speakers in the audible
frequency range.
2
Using the 4 adjustable feet and the supplied level,
level the turntable base left to right...
...and front to back. A bubble level can also be used, but
is not as precise as the line level in your kit. Make sure
all 4 feet touch the shelving to avoid rocking of the base
back and forth.
3 7
Clean all turntable parts using the Kronos cleaner. The
Kronos is finished in a luxurious brushed nickel. Wipe
on the cleaner and let it dry, the finish will remain bright
and clean. Avoid using cleaner on the platters where
the belts contact. A glass cleaner is a better cleaner in
that case.
Insert the supplied 4 spacer rings. This will simplify
4 8
assembly of the Kronos.
5 9
Place upon the rings the second level deck assembly.
Install the silver colored bearing well using the supplied
6 10
10-32 socket head screws. Do not over tighten.
Add 8 ml. of Kronos bearing oil. Make sure the
bearing shaft is oiled. A syringe is included in your kit
to facilitate this process.
Place the bearing ball on top of the bearing shaft.
Make sure it does not fall in the bearing well. The
bearing ball for the lower platter is made of steel, and
is silver in color.
Carefully deposit the balancer platter (the one without
the spindle) onto the bearing shaft. The platter
should rotate freely. If it does not, remove the
platter and make sure the ball is on top of the bearing
shaft.
Install the 3 belts onto the motor pulley and pick up
pulley. Make sure no grease or oil contact the belts. If
this happens, the belts can be cleaned using regular
glass cleaner.
11 15
Place the third deck upon the second deck assembly.
12 16
Slide in the 4 leg caps, making sure the socket head
screws glide into their respective holes. Wiggle
everything a little, the caps should find their way flush
against the deck.
Tighten the socket head screws. Do not over tighten.
13 17
14 18
Install the gold colored bearing well using the
supplied 10-32 socket head screws. Do not over
tighten. Add 8 ml. of Kronos bearing oil. Make sure
the bearing shaft is oiled. Place the bearing ball on
top of the bearing shaft. Make sure it does not fall in
the bearing well.
Carefully deposit the top platter (the one with the
spindle) onto the bearing shaft. The platter
should rotate freely. If it does not, remove
the platter and make sure the ball is on top of the
bearing shaft.
Install the top pick up pulley. Grease the pulley shaft
and also grease the shoulder of the shaft assembly.
Insert the pulley. Do not over grease. Once every 6
months or so, the pulley can be removed, cleaned
(along with the shaft) and re-greased. This will insure
better speed stability. Install the 3 belts as in step 10.
Install the tone arm board specified for the particular
tonearm you will be using. Install your tonearm using
a proper protractor and make adjustments.
Remove the white leg spacers by cutting the tie wraps.
Keep the spacers in a safe place, you will need them
if you need to move the Kronos, or if you need to
disassemble it for transport. Additional tie wraps have
been supplied for such an eventuality. It is very
important that the Kronos not be moved
without installing the white spacers.
Failure to do so could damage the speed
sensors located left of the platters.
Level the suspended turntable by loosening the screws
19
at the top of each leg (through the hole at the center
top of leg caps). Level the turntable left to right and
front to back. Tighten the set screws securing the leg
caps to the leg shafts
20
Connect the female end of the 2 pico cables to the
motor base. Be careful as there is a 3 pin cable and a
4 pin cable.
Connect the male end of the 2 pico cables to the
21
power supply. Be careful as there is a 3 pin cable and
a 4 pin cable. Connect the power supply to the AC
mains. The power supply AC input voltage is set at
the factory to either 110 volt or 220 volt. If a change
of AC input voltage is required, please contact us so
that you can ship back the power supply for a voltage
change and re-calibration.

Turn on the power switch on the power supply. The
turntable display will light on, and indicate 00.0. Place
and hold two fingers flat on the touch sensitive sensor,
on the left of the LEDs. The display will flash from 00.0 to
33.3. The platters will start rotating. Correct speed will
be attained in approximately 30 seconds. It could take a
little longer the first few times, as the system will need to
calibrate itself. Placing two fingers on the left again will
turn off the turntable, and the display will read 0.00.
Once the turntable is moving, placing two fingers to the
right of the LEDs will toggle from 33.3 rpm to 45 rpm.
Again, this operation may take a little longer in the
beginning as the system calibrates.
THANK YOU
for purchasing the Kronos turntable.
The Kronos has been designed to produce the best sound reproduction possible from a vinyl
record. It is built without compromise for this single purpose. It is a state-of-the-art hand built
instrument. Each Kronos is individually constructed, assembled and tested to ensure years of
musical enjoyment.
It is important that you take the time to read this manual before assembling, installing and
operating your Kronos. Assembly is simple, provided you follow all the necessary steps.
Leveling of the turntable is particularly important.
Once this is done, you will find the Kronos will not require frequent adjustments as it is a very
stable platform. Of course, mandatory care must be given to setting up the tone arm and
cartridge, as in any other turntable. Make sure you use a quality protractor to properly align
the cartridge.
Please keep in mind that your Kronos will need to settle for its first few days of operation.
The self-learning speed guidance system will calibrate itself with use. After a few hours it will
attain speed more quickly with a minimum of fluctuation. The micro-processor controlled speed
adjustments are deliberately done in a slow and deliberate manner. This use of minimal power
reduces motor induced vibration and hence optimum musical enjoyment.
Enjoy.
