Dear Customer
Thank you very much for your trust and for your purchase of a J.Sikora turntable. Please read this manual
carefully before assembly and first use of your table. Please do not disassemble any of the electronic parts
of the product; this will invalidate the warranty. Only the manufacturer, their authorized service agents, or
distributors are authorized to open any electronic parts.
Precautions:
- Do not plug in or turn on the power supply before the entire turntable assembly is fully completed.
- To avoid the risk of electric shock never touch any power cables with wet hands.
- When unplugging the turntable’s power supply, never pull the power cable out by holding the cord.
Always hold the plug rather than the cord.
- When choosing a location for the turntable, choose a place out of direct sunlight if possible. Avoid
putting the turntable next to devices emitting high levels of heat, such as Class A amplifiers, heaters,
radiators, or ovens. Excessive heat can damage or shorten the life of plastic elements, discolor
materials, and in extreme situations represent a fire hazard. Also, avoid placing the turntable’s power
supply next to your phono preamp. Some phono preamps can generate hum when placed too close
to a power supply
- The shipping box and some elements of the turntable are extremely heavy. Please get assistance
when moving the shipping container(s) and when setting-up or moving the turntable. We suggest
keeping the shipping box and packaging.

1.3 Unpacking
Your REFERENCE turntable ships in three boxes. Be careful, all of the boxes are very heavy!
Any additional Arm Towers, accessories, tonearms, and cartridges will be packaged separately. All elements
of the turntable are packed safely to protect them against damage in transport. The parts are located in
fitted nests in separate layers of foam. The protective cloth can leave lint on some surfaces. Use the included
lint-free cloth to remove any lint before assembling your turntable.
Before unpacking be sure that you prepare a space on which to assembly your turntable. If you think you
may need to re-pack the turntable sometime in the future, we advise that you take pictures of each layer
while you unpack the turntable. Print and store those images with this User Manual. Later, you can use those
pictures as a guide to safely re-pack the turntable.

2Turntable Setup
Warning! We strongly suggest setting up the REFERENCE turntable with the help of a second person. The
turntable is extremely heavy.
Before assembly, be sure that the rack and shelf you will be using for your turntable is level. Carefully check
each direction with a spirit level. The turntable does have leveling adjustments, but it always better for you
to make the major leveling adjustments to the rack and then perform only the fine leveling with the
turntable’s feet. It is far easier to adjust your rack without a heavy turntable on it.
2.1 Set the Isolation Base
2.1.1 Place the Isolation Base
The Isolation Base is heavy, so if you place the Legs directly on your shelf, it may well scratch the shelf. So, a
set of leather J.Sikora Coasters are included for you to set under the Legs of the Chassis during the setup
process to avoid damaging the shelf.
Note where the points of the Feet of the Isolation Base are located. There are two Legs on the bottom of
one side of the Isolation Base and one Leg on the other side.

Place the coasters in the approximate position where you would like to Legs to sit.
Ideally with the help of another person, slowly lower the Isolation Base onto the Coasters. Once on the
Coasters, gently slide the Isolation Base to its desired location.
2.1.2 Add Isolation Feet
The next step is to replace the Coasters with the Isolation Feet, which are composed of Aluminum Discs and
large Ceramic Ball Bearings. These parts will act to isolate the table from the shelf
Locate the bag with the three Aluminum Discs. Place the Discs on the shelf.
Next, locate the bag with the three large Isolation Ball Bearings. Note that there will be another bag of with
much smaller Ball Bearings. You will use the small bearing later.

Now, place one of the Bearings into the indent on the top of each Disc to create the assembled Feet.
You will now place one of each of the Feet under each Leg of the Isolation Base.
This is one of the trickier steps, so grab a friend to help if you can. First, lift one corner of the Isolation Base
and remove the Coaster. We find it easier to lift the Foot into the foot into the Leg and then lower the
Isolation Base. Doing this with another person will make this step much easier and will help insure you line
the bearing of the Foot with the indent in the Leg. If you lower the Isolation Base without the proper
alignment, you may end up chasing Bearings across the room. While this is no fun, you will not damage the
Bearings. Take a deep breath and try again. Repeat this procedure for the other two Feet.
2.1.3 Level the Isolation Base
If you were not able to level your shelf, you can use adjust the feet on the Isolation Base to level the
turntable.

Even if you leveled your shelf, sometimes the weight of the Isolation Base can impact the leveling of your
furniture. Center the included Bubble Level on the plinth to determine if your table is level in all directions
(front to back and side to side).
Check Level of Isolation Base
If your turntable requires levelling, insert the black wrench into one of the holes in the Leg on the side of the
Isolation Platform that needs to be adjusted.
Using the wrench, rotate the Leg clockwise to raise the Foot and counter-clockwise to lower the Foot. Repeat
that process as needed with the other Legs.
