One world class power supply, two output technologies.

Over four decades of R&D, we’ve learned to take innovative leaps one at a time. Since PowerLight™ remains the world’s most effi cient supply, we developed new output stages.

PL340 & PL325:

Ultimate Class H Technology

We design for the total show: load-in to load-out and everything in between. That’s why the 2-tier linear PL340 and PL325 not only have ruler-fl at response into 8 ohm loads, but similar transparency and detail into 2 ohms.

PL380: Ultimate Class D Technology Class D amplifi er design offers ultimate power conversion effi ciency and entails greater complexity than linear topologies. It is also harder to master since it has more signal-conversion stages, each a source of errors that must be corrected. The PL380
