Fo' Shizzle Amp'in Nizzle


"The flagship of the PowerLight 3 Series is the new 8000 watt PL380. This highly refined, all-switchmode amplifier incorporates nearly 40 years of QSC engineering experience, resetting expectations for Class D audio quality. The PL380 combines a pair of 4000 watt Class D amplifier channels with the well proven PowerLight supply, to deliver more than twice as much audio power as previous 2 rack unit PowerLight amplifiers. Reactive "back EMF" from the speaker is recycled to the power supply, and unmatched "plug-to-plug" efficiency of 85% keeps AC power needs to a minimum, while delivering more energy to the speaker. "

PL325 = class H
PL340 = class H
PL380 = full range class D

X 2. Those are some decent numbers on the THD, seems they would be some clean amps. I would still prefer a Mac. Maybe by Christmas...:crap:

Hmmm, looks good to pick one of these up for my mids and demote the CX902 down to subwoofer duty.

Since I've already got one powerlight HV, might as well make it two.

class h has been around for a while, i remember my mid 90's Technics receiver used class h amps

there are also class g and class t as well and maybe a few more

a/ab/d are the most well known though

Class H = class AB + two or more tiered power supply rails [vs. one tier], used to
reduce heat generation.

When PLX2 series came out last year, PLX prices fell on the used market as
people sold the old to get the new. Same scenario here, maybe some people will
sell QSC's in favor of the newer ones. Would be nice to see QSC PL6.0II prices fall
as people want the new ones. heehee
