Ultimate Audio Performance
One world class power supply,
two output technologies.

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
Power, fl exibility, pristine audio quality and legendary
QSC reliability — the ultimate concert amplifi ers.
