The Artemis Labs PL-1 Phono Preamplifier is the result of several years
of perfecting a simple yet extremely high quality tube-type preamp. High
quality parts are used throughout and the design is rugged and reliable.
The sonic qualities: tonality, detail, smoothness, and presence are outstanding.
The PL-1 is optimized for low-output moving-coil cartridges. See information
on the Artemis Labs PH-1 for a preamp optimized for medium- to high-output
cartridges.
Key Features:
70dB of gain with low hum and noise
High-quality step-up transformer gives good hum and noise rejection.
TexTool™ ZIF socket connected to step-up transformer secondary
Allows any shunt loading resistor or capacitor to be effectively attached
to step-up secondary.
Three stage design with passive RIAA equalization
Equalization is flat within +/- 0.2dB from 20Hz to 20KHz and is flat to +/-
0.5dB to 40KHz. Last two stages have gentle
feedback and can drive as low as 8K loads without the use of cathode followers.
All key audio circuits wired point-to-point using military-style
terminal boards
Sonic degradation due to fiber-glass PC boards is minimized.
One 6N1P tube, two 12AX7/ECC83 tubes and two 5687 tubes. All but
6N1P are run in Cool-Swap™ Configuration
An idle spare in each tube, plus tubes run cooler.
Choke loads for each triode
Allows tubes to run in their most linear mode and permits lower plate supply voltage
Low-Gain MOSFET high voltage regulation
One regulator per channel minimizes cross-talk and gives a firm, stable sound
without sounding “solid-state”.
All Artemis PreAmps Designed and built in the United States using
the best parts from around the world.
