6. Feature summary

6.1. Ampliﬁ er Platform Features

• Four channels with three levels of total available frame power output: 20000 W, 12000 W,

and 5000 W (@ 2.67 ohms)

• Rational Power Management (RPM)

• True ﬂ exibility in allocating power output across each channel to match requirement for more efﬁ cient use of

ampliﬁ er inventory

• Any channel is capable of delivering up to 5900 W (PLM5K44 = 2000 W) power output drawing from total

available power in each frame

• Dedicated on-board surveillance and load monitoring for voice alarm applications

• Advanced universal power supply

• Regulated Switch-Mode Power Supply (R.SMPS™) maintains stability through ﬂ uctuations in mains voltage

• Best-in-class Power Factor Correction (PFC)

• Current Draw Modeling (CDM™) reduces peak mains draw

• Breaker Emulation Limiter (BEL™) responds to available mains distribution

• Under-Voltage Limiting (UVL™) allows continued operation through mains voltage drop

• CAFÉ (Conﬁ guring Ampliﬁ ers For the Environment) software incorporates ESP™ (Equipment Speciﬁ cation

Predictor) to assist in design, equipment speciﬁ cation and commissioning

• Features controlled by on-board DSP

• Amp Gain (Sensitivity) - Input gain (sensitivity) is set in the digital domain and controlled via

Lake Controller software

• ISVPL™ - The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each channel’s power output to the

characteristics of the connected load.

• Load Veriﬁ cation & Performance Monitoring - A comprehensive set of proprietary DSP-based tools

enables load veriﬁ cation and real-time performance monitoring.
