Features + Benefits:
+ Rational Power Management (RPM)
• 4 x 3000 W output power, total 12000 W (12K44)
• 4 x 5000 W output power, total 20000 W (20K44)
• Any channel is capable of delivering up to 5900 Watts
power output from total available power
• Flexible power output allocation across channels of
the 12K44 model to match requirements, enabling more
efficient use of amplifier inventory

+ Power Supply
• Unique universal Regulated Switch-Mode Power Supply
(R.SMPS™) maintains stability despite wide fluctuations
in mains supply voltage
• Best-in-class Power Factor Correction (PFC) helps
maintain full output during extended power bursts
• Current Draw Modelling (CDM™) reduces mains peak draw
• Breaker Emulation Limiter (BEL™) tailors PLM+ Series to
the available mains distribution
• Under-Voltage Limiting (UVL) enables continued operation
with mains voltage sags as low as 65 V

+ Amplifier
• Amplifier Design: Class TD output stage
• Digitally controlled and recallable “amplifier gain”
adjustable in 0.1 dB steps
