Set-Up & Operating Manual
Important Safety Instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
6. Clean only with a dry cloth.
7. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers).
9. Do not defeat the safety purpose of the grounding-type plug. A grounding-type plug has two blades and a third grounding prong. The third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, conve­nience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Unplug this apparatus during lightning storms or when unused for long periods of time.
13. Refer all servicing to qualified service personnel. Servicing is required when the appa­ratus has been damaged in any way, such as if the power-supply cord or plug is damaged, liquid has been spilled inside the appliance or it has been exposed to moisture, the appli­ance does not operate normally, or has been dropped.
14. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
Explanation of Safety Symbols:
CAUTION: To reduce the risk of electric shock, do not remove the covers. No user-serviceable parts inside. Refer Servicing to qualified service personnel.
This symbol is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of elec­tric shock to persons.

INTRODUCTION & SPECIFICATIONS
The Artemis Labs SA-1 Turntable puts a sonically excellent design into an attractive and compact pack­age. It was designed by Frank Schröder, of Berlin, based on years of experience in the fi eld of reproduc­tion of vinyl records. The motor controller was designed by John Atwood. This manual will help you set-up and get the most out of your SA-1 turntable.

DESCRIPTION
Some of the features that set this turntable apart from other designs past and present are:
THE PLATTER
The 15 pound platter is made from anodized aircraft grade aluminum alloy, turned to an extremely tight tolerance (± 5 microns) in all directions.
The platter’s thickness is maintained from center to the outer rim to avoid variations in the mechanical impedance “seen” by the cartridge.
The platter is damped with a proprietary paper/felt inlay, allowing for the use of three different platter­record interfaces:
• Foam bubble mat for effi cient decoupling of the record if so desired
• Acrylic plastic for excellent mechanical impedance match with the vinyl record
• Graphite mat for rigid coupling and fast energy transfer
Each of these will be optimal for specifi c applications and allow the user to “fi ne-tune” the overall tonal balance of the system without sacrifi cing detail resolution.
The acrylic and the foam mat come standard with the table, the graphite mat can be ordered separately and all are easily interchangeable.
THE BEARING
The massive, 3 pound bearing is of the non-inverted type, utilizing a large diameter, case hardened spindle and unusually long self lubricating phosphor bronze bushings. The clearance is kept very small, but the defi ned surface “roughness” of the spindle maintains an extremely stable oil fi lm and creates drag at the same time.
The bearing is sealed and will maintain its super low noise performance for many years without the need for cleaning or re-oiling.
The centering pin is formed center each record perfectly when “dropped” onto the platter, but doesn’t make contact with the record once on the mat. This lowers the noise fl oor even further and allows the user to “re­true” records with an off-center hole, a frequently encountered sign of lack of quality control on the part of today’s record pressing plants.
If the user wishes to opt for a record weight or clamp, he may do so, but few are recommended if the above advantage is not to be sacrifi ced. Artemis Labs will soon be able to provide a small record weight perfectly suited for this turntable.
THE PLINTH
The plinth is constructed from three layers of bamboo ply and ebony, each bamboo layer made up of three layers of different grain orientation. Medium mass and very high internal damping in conjunction with a rigid coupling to the supporting platform provide an effective mechanical ground. Vibrations generated by the table are dissipated in the plinth, footfall is well controlled despite the lack of a suspension (a can of worms in itself).
The plinth rests on three cones, one made from Dural and two of a hard polymer. Stillpoints™ component feet are available as an option. See www.stillpoints.us/the_design_.html for more information.
