Artemis Car Amplifier LA-1 Manual De Usuario
INTRODUCTION & SPECIFICATIONS
Page 3
The Artemis Labs LA-1 Line Amplifier combines the clean, accurate sound of a purist single-triode line
amplifier with the convenience and reliability of a solid, well-built product. Special care is taken with all
parts in the audio path, from the Goldpoint™ stepped attenuator to the Swedish output chokes by Lundahl.
All aspects of the design were done by John Atwood of One Electron™.

The LA-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
LA-1. The Warranty is on a separate card. Read it and send it in to get full warranty coverage.
