INTRODUCTION & SPECIFICATIONS
Page 3
The Artemis Labs DP-2 Power Amplifier is a purist design comprising a pair of mono-block amplifiers.
It uses the classic 2A3 directly-heated triodes in push-pull class-A with transformer phase splitting.
Careful power supply filtering and regulation of critical voltages ensure stable, quiet operation.
Given that the DP-2 amplifier puts out about 10 watts per channel, it must be used with relatively effi
-
cient loudspeakers. The minimum efficiency required depends on many factors including room size,
room absorption, preferred listening levels, etc., but in general, an efficiency of 92dB or higher per watt
at 1 meter is needed. Work with your dealer for the best speaker combination for your listening set-up.
The DP-2 is conservatively designed and is built to last for many years. The only maintenance needed
is the occasional replacement of tubes. Please read this entire user’s manual so that you can understand
all the features and get the most from the DP-2. The Warranty is on a separate card. Read it and send it
in to get full warranty coverage.
