1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with a dry cloth.

7. Do not block any ventilation openings. 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 PL-1 Phono Pre-amplifier is specifically designed for low-output moving-coil
phono cartridges. It combines the clean, accurate sound of a purist phono preamplifier with the con
venience and reliability of a solid, well-built product. Special care is taken with all parts in the audio
path. All aspects of the design were done by John Atwood of One Electron™.

The PL-1 is conservatively designed and is built to last for many years. The only maintenance needed
is the occasional replacement of tubes, and even this has been reduced by the use of Cool-Swap™
technology. Please read this entire user’s manual so that you can understand all the features and get
the most from the PL-1. The Warranty is on a separate card. Read it and send it in to get full war
ranty coverage.
